Are you certain the system is adequately charged? There is a low-coolant
cut-out switch on one of the coolant line that can be shorted to test
whether the compressor engages. If the compressor kicks in when the
switch
is shorted then you can conclude your system might only need to be
charged.

Ok, I did some checking and repairs.
The 2 resistors under the left side headlight where broken (old),
Then the auxilary water pump was ceases because of a leaking sensor
wired to it. Both were replaced.
My 50amp fuses are not blowing anynmore.

Now I'm getting to the A/C that is not working.
I tried this afternoon to turn on the contact without starting the
engine and turn on the A/C.
The front fans on the radiator are not starting so I conclude I have
to go through the checks for the 5 relays on top of the left side
headlamp.

Can someone confirm that this will be the 1st step.
Again, my A/C is not starting, the Compressor is not engaging,
and the fans are not starting.

Thanks

Christian,

Here's a short summary of where the fans and coils and controls
are
located
on your EV, and basically what they do. Remember, these things
work by
moving HEAT around (you don't move "cold" around). You making
something
hotter by moving heat in, and you make something cooler by moving
heat
out.


Fans (two) -- under the hood:

There are two fans under the hood. They work together at all
times and
run
at three different speeds (between each fan and the engine is a
plastic
shutter system than opens and closes by a mechanical lever
controlled by
expanding/contracting wax). The three speeds are controlled by a
set of
relays (behind the driver's side headlight) that determine which
circuit
supplies the fans with current. Those relays send current
through a pair
of
heavy-duty resistors (under the headlight behind an exterior
panel) to set
the various speeds. The entire circuit is protected by three
fuses -- one
inside the EV on the fuse panel (controlling current to the
relays), and
the
other two in the small plastic housing behind the headlights
(controlling
current to each fan). Practically every component mentioned
above will
need
to be repaired/replaced at some point.


Coils (two) -- under the hood:

In front of of the two fans are two coils. One is the radiator,
which
moves
heat out a mixture of water and anti-freeze for the engine and
passenger
compartment heaters, and the other is the evaporator, which moves
heat out
of R134a refrigerant for the air conditioning system. The coils
themselves
will quite possibly last the entire life of the vehicle. There
are a
bunch
of control/sensor/sender components along the coolant lines and
along the
refrigerant lines that will eventually fail and will then need to
be
diagnosed and repaired. The lines and hoses connecting all this
stuff
together are generally very reliable, but there are a few hoses
and
fittings
(just a few) that are known to fail.



Fans (two or three) -- in the cab:

There is a large interior fan under the dash that force passenger
compartment air and/or fresh air through the coils under the
dash. There
is
also a fan on the floor forcing air through another small coil,
and a fan
in
the back (if you have rear air conditioning) forcing air through
yet
another
coil and distributing it through the roof vents. All or these
fans are
multiple speed (determined by resistors) and are protected by
fuses on the
fuse panel. The large interior fan can suffer bearing failure,
and
resistor
packs can fail too.



Coils (three or four) -- in the cab:

Under the dash and near the large interior fan are two coils.
One is the
heater coil, containing a mixture of water and anti-freeze, which
moves
heat
into the cab when the 4-speed fan is running and red/blue
temperature
controls are set the right way. The other coil is a condenser,
containing
R134a refrigerant, which moves heat out of the cab when the 4-
speed fan
is
running and red/blue temperature controls are set the right way.
There is
also a small coil containing water/anti-freeze underneath the
floor near
center of the rear cab for moving heat into the rear. Finally,
if you
have
the rear air conditioning option then there is another coil (a
condenser
containing r134a) for moving heat out of the rear passenger
compartment.
Again, the hoses, lines, fittings and control gizmos connecting
all this
stuff together might fail, but the coils themselves will most
likely last
the entire life of the vehicle.

Hi Jerry,

Fans are working and is roaring load. This happens
during city drive. I am not towing anything and the
coolant level is in Max. I have not turn on my heater
and when it hits 230 my A/C is not turn on.

This puzzles me a lot. There is no engine leak that I
know of.


I will looking to this tommorow and will post later

Re: Need urgent opinions on '91 Eurovan

Stephen Kramar
 

My 2.5L has been making a ticking noise for over 100,000 miles (~143K right
now). You can basically only notice it when the hood is open. I don't have
piston slap noise.

Pulling the radiator forward (remove four bolts) gives more room, but
working on it can still really be a pain. I haven't replaced my timing belt
yet, though I worry about it off and on. Most on this list would suggest
replacing it around 100K.

EVs with VR6 engines have a larger engine compartment -- the nose sticks out
further. I don't think it is possible to put a VR6 in the older frame
without some serious body modifications.

Just looked at a Westfalia this evening. My wife and I were
originally planning on spending around CAD$8000 (USD$5000) on a
Vanagon and then doing a motor swap but came across a '92 Eurovan
Westy for CAD$19,000 (USD$11,875) tonight. It was in immaculate
condition and has 185,000km (115,000 mi) on it.

Every looked good except the motor (Audi 2.5L) made a kind of a
ticking noise. It wasn't exactly a tick sound but similar...maybe a
small exhaust header leak...or maybe it was normal, I'm not sure.
When it first started up, the motor sounded a bit noisy (remotely
similar to a diesel) but smoothed out with 1 or 2 seconds. Now, I've
heard that '93 EVs had a piston slap problem and I am wondering if
that's what I heard on this '92. Opinions?

If it is a piston slap problem, would VW provide a cheap replacement
motor if I'm the 2nd or 3rd owner? Ok, stop laughing, it was worth a
shot.

Is the piston slap problem serious or just an annoyance? Some Jeep
4.0L motors had the same problem but it wasn't supposed to adversely
affect the motor's lifespan (although I've been skeptical).

Anything else I need to watch out for? I might have another look at
it tomorrow in the daylight.

Oh, I do all the work on my wife's Subaru and my Jeep YJ. They're
both really easy to work on. The EV's engine compartment looked very
crowded. Anyone have opinions on that? Is it a real bear to work
with?

When does the timing belt need to be changed and how ugly is the
job? What about the water pump?

One more question: how many miles or km can I expect to get from the
2.5L motor? Has anyone swapped in a VR6? How difficult was the job?

Thanks in advance for taking the time to answer my newbie questions.

Both Fans are running an like roaring very loud. I

boiling. Anyway, I will take the van to my mechanic
tommorow.

I have gathered all responses from members that
responded and have them check against the situation.

The belly pan does need to be removed for oil changes, so you need to

Re: 93 evmv cooling fans

 

Christian,

My 1st thought on your problem having trouble shot my fans which
included reviewing the bently manual is a possibility that a single
fault may be cause of your lack of AC and fans working.

The AC electrical circuit is set up so if your AC is engaged +
ignition switch is on, then the fans should both come on at low speed.
If the 2 problems are related, trouble shooting the relays will not
find this problem. I suggest you 1st look under the dash to make
sure all electrical/vaccum lines are connected to the HVAC controls.
I'll check the bentley manual tonight for you if there is anything
else to check while you're under there.

While you're waiting to hear back about this, I suspect you'll do OK using the Goodyear, it being the same size/load rating/general specs as the Agilis. If you want two similar tires on the same axle get a pair of Nokian NRWs for the rear and put the remaining rear Agilis on as the spare.

Almost any RV dealer sells propane. Even most RV campgrounds such as KOA
and others. I've seen lots of gas stations that also sell it but beware of
their higher costs and minimum charge. Your best bet is probably any Flying
J travel plaza whose prices are amongst the cheapest and while they
sometimes quote a minimum charge, I've seldom seen them enforce it.

Re: 93 evmv cooling fans

Are you certain the system is adequately charged? There is a low-coolant
cut-out switch on one of the coolant line that can be shorted to test
whether the compressor engages. If the compressor kicks in when the switch
is shorted then you can conclude your system might only need to be charged.

Ok, I did some checking and repairs.
The 2 resistors under the left side headlight where broken (old),
Then the auxilary water pump was ceases because of a leaking sensor
wired to it. Both were replaced.
My 50amp fuses are not blowing anynmore.

Now I'm getting to the A/C that is not working.
I tried this afternoon to turn on the contact without starting the
engine and turn on the A/C.
The front fans on the radiator are not starting so I conclude I have
to go through the checks for the 5 relays on top of the left side
headlamp.

Can someone confirm that this will be the 1st step.
Again, my A/C is not starting, the Compressor is not engaging,
and the fans are not starting.

Thanks
Christian

Christian,

Here's a short summary of where the fans and coils and controls
are
located
on your EV, and basically what they do. Remember, these things
work by
moving HEAT around (you don't move "cold" around). You making
something
hotter by moving heat in, and you make something cooler by moving
heat
out.


Fans (two) -- under the hood:

There are two fans under the hood. They work together at all
times and
run
at three different speeds (between each fan and the engine is a
plastic
shutter system than opens and closes by a mechanical lever
controlled by
expanding/contracting wax). The three speeds are controlled by a
set of
relays (behind the driver's side headlight) that determine which
circuit
supplies the fans with current. Those relays send current
through a pair
of
heavy-duty resistors (under the headlight behind an exterior
panel) to set
the various speeds. The entire circuit is protected by three
fuses -- one
inside the EV on the fuse panel (controlling current to the
relays), and
the
other two in the small plastic housing behind the headlights
(controlling
current to each fan). Practically every component mentioned
above will
need
to be repaired/replaced at some point.


Coils (two) -- under the hood:

In front of of the two fans are two coils. One is the radiator,
which
moves
heat out a mixture of water and anti-freeze for the engine and
passenger
compartment heaters, and the other is the evaporator, which moves
heat out
of R134a refrigerant for the air conditioning system. The coils
themselves
will quite possibly last the entire life of the vehicle. There
are a
bunch
of control/sensor/sender components along the coolant lines and
along the
refrigerant lines that will eventually fail and will then need to
be
diagnosed and repaired. The lines and hoses connecting all this
stuff
together are generally very reliable, but there are a few hoses
and
fittings
(just a few) that are known to fail.



Fans (two or three) -- in the cab:

There is a large interior fan under the dash that force passenger
compartment air and/or fresh air through the coils under the
dash. There
is
also a fan on the floor forcing air through another small coil,
and a fan
in
the back (if you have rear air conditioning) forcing air through
yet
another
coil and distributing it through the roof vents. All or these
fans are
multiple speed (determined by resistors) and are protected by
fuses on the
fuse panel. The large interior fan can suffer bearing failure,
and
resistor
packs can fail too.



Coils (three or four) -- in the cab:

Under the dash and near the large interior fan are two coils.
One is the
heater coil, containing a mixture of water and anti-freeze, which
moves
heat
into the cab when the 4-speed fan is running and red/blue
temperature
controls are set the right way. The other coil is a condenser,
containing
R134a refrigerant, which moves heat out of the cab when the 4-
speed fan
is
running and red/blue temperature controls are set the right way.
There is
also a small coil containing water/anti-freeze underneath the
floor near
center of the rear cab for moving heat into the rear. Finally,
if you
have
the rear air conditioning option then there is another coil (a
condenser
containing r134a) for moving heat out of the rear passenger
compartment.
Again, the hoses, lines, fittings and control gizmos connecting
all this
stuff together might fail, but the coils themselves will most
likely last
the entire life of the vehicle.
