Re: 97 EVC battery replacement Surprise

 

So much for that stab in the dark!? ?Makes sense that reverse would be the last thing the TCM needs to manage and one of two gears left functional in limp mode.?

I did the replacement several years ago. It’s a beast of a job. Everything has to come out, steering wheel, dash etc. It took me over 20 hrs personally!!?

I was driving on Tuesday (SoCal heat wave) when I had an odd smell coming through the vents.? Then some fogging on the window.

I suspected a coolant issue and saw my reservoir was empty.? I needed to get somewhere to leave it, and I hobbled to a lot.? As I my 1993 EV was hobbling, some hot liquid came out of the dash and splashed on my foot.? Therefore, I'm suspecting that it is the heater core.? I don't have time to fix properly so I'm going to try a bypass tomorrow.
Any tips from people that have bypassed the heater core on a 1993?

I missed the last message but yes the front part is the AC condenser. Where did it turn out your radiator was leaking from?

Re: 97 EVC battery replacement Surprise

 

Thanks to all who responded.

Shortly after replacing the battery and losing reverse AT ONCE, and upon research I knew the tranny needed to be reset. Since there was absolutely nothing wrong with the tranny which was running like a dream machine after many, many years of tinkering. Unhappily, reset did not work after multiple attempts. Have not try yet but planning to do disconnecting then reconnect and reset.

Old battery was struggling to turn engine over but new one is not better. Starter is original and could be shot. Had wanted to replace it some years ago but could not get to a?
mounting bolt. Maybe time to retry Could there be a connection here and lost of reverse gear. Wondering.

AC?


Re: 97 EVC battery replacement Surprise

 

Agree, I would reset. If the battery was out for a while or went completely dead he probably has to do a reset, no? I know one time our battery went dead dead and I had to do the reset thing. I don't remember losing reverse but it was very obvious, and alarming, problem. Directions are in the files.

In any case, a valve body is far easier to rebuild/replace than the transmission if that's the source of the reverse issue.? There are folks who assert that many or most EV tranny issues come from the valve body, not necessarily the transmission proper.? ??

Re: 97 EVC battery replacement Surprise

 

Most likely coincidence. Loss of reverse gear is the first sign of a failing transmission valve body.

Re: 1993 EV - heater core failure (I think) in SoCal

 

Tackling the radiator replacement finally... this weekend.
Already started with basic inspection, draining, etc.

Using this video as a guide -?

But, it appears that my front has what I guess is an AC heat exchange... or possibly trans cooler... in front of my radiator.? Thinking the AC from where the lines appear to go.

Can anyone confirm what the "front front radiator" is? I think I'll be able get behind it to swap the radiator.
With this "front front radiator", it is difficult to pinpoint the leak.? But it is definitely coming from the cooling system... and the area indicates the radiator.

I'll post back progress/completion when done.

Exhaust manifold removal - 1993 Eurovan

 

Has anybody ever removed the exhaust manifold from a 1993 Eurovan?
Or do you have any resources/videos on how to do so?

I've looked at the Bentley, but sometimes on complicated tasks, I can't make sense of it... and I like to get more help/info.

That's probably not the answer either. He reports that the water pump works- it draws lots more current than a light bulb. Since all the lights are one one circuit ( both hot and ground) I suspect either a bad connection to a breaker( one breaker handles all lights) or a bad breaker? itself. Easy to check. Water pump and control panel are on a separate circuit, ground and breaker.

The reading lamps above the bed, the galley light and the pop-top light all share a common ground- and they are the only items on that ground. They also share the same circuit breaker! So- it could be a bad ground, a bad 12 v supply wire, or the circuit breaker. I would pull the circuit breaker panel and make sure you have 12 volt on the outputs of all the circuit breakers first. The open up one of the reading lights or galley light and make sure you have a good chassis ground ( I usually use a screw on the control panel). I can send you a detailed drawing if you would like.

Re: 2000 EVC w/ Camper electrical quirks -- #electrical

 

Sounds to me like the battery is completely flat.

Battery voltages will drop when you turn things on (which can of course cause the LP alarm to start).

I would start by measuring voltage at the house battery with engine off.??Start the engine and see if the voltage rises.??If the voltage rises, then test all the systems with the engine running.??If the voltage doesn’t rise then the charging system is toast.

I would also try removing the house battery and putting it on a decent intelligent charger and see if that tells you the battery is toast.

Re: 1993 EV - heater core failure (I think) in SoCal

 

So based on the condition of the radiator and the leak, I've decided to replace the radiator and hoses.

While the radiator is off, I also intend to do some other maintenance.? I'm looking for suggestions of other tasks.? Please keep in mind that this 1993 Eurovan has been reliable, but has had little maintenance done in the last 6 years.

  • Radiator & hoses
  • Coolant temp sensors
  • Valve cover & grommets
  • Touch up rust/metal on headlight/radiator assemblies
  • Replace filters (air, fuel, oil/oil change, etc)
Also, I've been looking for any how to's on how to remove an exhaust manifold.? I'm not sure that I want to take that on now, but if anybody has a video/docs, please let me know.? I have Bentleys that I'll be reviewing as well.
