I recently rebuilt my head because of a blown valve and burning oil (probably because I overheated it). Since the rebuild it still burns oil but doesn't seem to be as much. Also the temp gauge is always at around 3/4 which I thought was pretty high. I replace the thermostat, gaskets, and radiator temp switch. The radiator is 1 or 2 years old so pretty new and same with the water pump. Should I replace the temp gauge sensor or try another radiator cap?
Does anyone have any suggestions what could be giving me such a high temp reading.

Re: 85 tercel - high temp gauge
Is your electric fan working properly? When you rebuilt the head, where the coolant passages cleaned properly? Are you sure you put the right thermostat in? It could be a problem with the guage, but I think it is unlikely.reebs wrote:I recently rebuilt my head because of a blown valve and burning oil (probably because I overheated it).

I believe so, after I run the car for a while idling the fan kicks on for a few seconds and then kicks off. When we rebuilt the head I am not sure if the cooling passages where cleaned because my grandfather did that part.
Is there anyway I can check to make sure that coolant is actually flowing properly. I thought I read somewhere that you could open the radiator cap when cool and start the engine and allow it to warm up and watch the coolant to see if it lowers. Is that correct?

i've had bad luck with thermostats on these carsreebs wrote:I believe so, after I run the car for a while idling the fan kicks on for a few seconds and then kicks off. When we rebuilt the head I am not sure if the cooling passages where cleaned because my grandfather did that part.

the common (less expensive) brand called "stat" or something that we have around here has not worked well. the beck / arnley (more expensive ) has saved the day several times.
the only other thing that has caused them to run warn is a head gasket leaking exhaust into the coolant.
it's hard to watch the water flow on these radiators because of the offset fill hole
Love those Tercell 4x4 wagons but they sure suffer from road noise.
Thermostat choices...
thermostat...OEM...Robert Shaw...BeckArnley...no Stant?
I'm using a Stant I think..no problems....except under some conditions the temp it holds varies some.
* Symptoms of a blown head gasket: Start car cold with cap off and coolant visible...look for a small stream of bubbles...if you see any, this is probably an exhaust into coolant leak. If you get serious bubbling in the resevoir when the car is hot and it overheats, this pretty much confirms it.
I've heard that if you overheat a car...it stresses the thermostat and maybe the sending units to the point that they can fail or not work right.
I recently overheated a V6...didn't do any damage I can see so far...probably because I had too much antifreeze in it...I think it's when they get hot enough that the coolant flashes into steam...that blows heater cores and rads...and really allows overheating of the block and head. I was lucky.

Give a boy a gun-give a biatch a cell phone-and pretty soon you almost got yourself a police state.
