Re: [WT] F134 Cooling Circuit

 

I vote for the upside down thermostat. That is a common mistake

At this time, the prime suspect is a failed or mis-installed
thermostat.The heater hose getting hot demonstrates that the water pump is
functioning, and that coolant is circulating.

I opened this valve and find the hose connected to get hot fairly
quickly. I then felt the large hose going to the bottom of the
radiator and it too is hot. However, the large hose to the top of
the radiator is cool. The gauge shows the engine getting hot in only
a couple of minutes so I shut it down. Since this is the first time
I put coolant in it is there something I am missing?

Thanks,
John

On the rear of my engine is a water valve that directs flow to the
heater in my cab. From the heater another hose runs to the water
pump.
I do not have my heater mounted yet but want to drive my truck. I
connected a single hose directly from the valve to the water
pump. It
is necessary for this valve to be opened all the time for engine
cooling to take place? I'm not certain if they opened in the
winter
months and closed it completely during the hot summer months when
cab
heat was not needed. Would someone please educate me on this
matter.
I closed it completely and it seems my engine got hot fast.

Thanks,
John
