Re: CTS questions
I guess nobody knows?
Anyway, I brought my IR thermometer home today and scanned the engine. The radiator appears to be doing its job, about 50 degrees cooler on the bottom hose. With the gauge reading 3/4 up, I get a reading of about 190-200 degrees on the surface of the top hose and about 150 on the surface of the bottom hose. Does this sound like an accurate gauge? Is there a pin on the ECM that I can put a volt meter on to see what temp the ECM is seeing? Do the ECM and gauge use different sensors for engine temp? Another thing, it seems the left bank of the engine runs a bit hotter than the right bank, according the temp reading of the valve covers, there is about a 20 degree difference. Seems odd to me. Any input?
