yesCool we got a starting point at 165 it should be around 20 +/- ohms, sounds like a bad sending unit, you have a ohm meter and know how to use it?

ok - gotta ask the obvious question then - are you SURE you have the correct amount of antifreeze vs. H2O in there? and are you sure you have good flow throughout?I know the circuit is good because the needle starts at C and slowly creeps up to H.
Other than that. I don't know much. In the winter, it stays at operating temp. 1/3 climb of needle. In the summer it goes to H. I use a heat sensor gun and it registers about 165 degrees without a thermostat and 185 with a 180 degree thermostat. But the temp gauge reflects engine is overheating.
Take the lead off the sending unit when it is cold read the ohms it should be around 73, warm it up 23 is the half point and ten is hot, if it goes right to ten at running temperatere call it 180 it is a bad sending unit. Understand it?
temp gun it is right so indication problem.ok - gotta ask the obvious question then - are you SURE you have the correct amount of antifreeze vs. H2O in there? and are you sure you have good flow throughout?
got yatemp gun it is right so indication problem.
I will try this...thank youTake the lead off the sending unit when it is cold read the ohms it should be around 73, warm it up 23 is the half point and ten is hot, if it goes right to ten at running temperatere call it 180 it is a bad sending unit. Understand it?
Karl? I am thinking that is the voltage limiter you are talking about it controls the temp, gas and oil gauges if the other two are fine it is ok.So what about that relay or diode, I read somewhere in the past that there is an electronic piece associated to the temp gauge that if it goes bad will affect temp readings. Anyone know what I'm referring to. It's suppose to be attached to the dash panel near the temp gauge
Hopefully that is it that is the easiest and cheapest to change out.I will try this...thank you
Flow, yes. Antifreeze water combo; if anything, it has more antifreeze than watertemp gun it is right so indication problem.
You said PULL!
Cool thought that was a good one you and Mitch are the only ones that have tried it, just used one the other day off the car to test those clusters I pulled, love that thing!
Yes, the voltage limiter; well the oil pressure gauge is on the high end too but I was thinking that was because of the high pressure/volume oil pump installed. Fuel gauge is fineKarl?

Hey we could be the helpline Karl with Small blocks, Scampy with radiator supports, Chris with, well I better not post it, and me with just general mischief!
That makes sense, I would test the sender first and go from there no sense throwing parts at it.Yes, the voltage limiter; well the oil pressure gauge is on the high end too but I was thinking that was because of the high pressure/volume oil pump installed. Fuel gauge is fine
And I'm just here, just a good fer nothin'!Hey we could be the helpline Karl with Small blocks, Scampy with radiator supports, Chris with, well I better not post it, and me with just general mischief!
And then there is George........
I hate that, the tach set up my kid got me is off drives me nuts, cannot find the right sending unit for it.
Puzactly!And then there is George........
