Northstar Engines and System Technical Discussion Discussion, BARS Head Gasket Fix and Aux Fan control in Cadillac Engine Technical Discussion; I beleive the engine temp sensor is either not sending the proper signal to start the fan, or the engine ...
I beleive the engine temp sensor is either not sending the proper signal to start the fan, or the engine computer is not sending the signal. The relays are fine as the external temp control I installed uses the relays to start both fans at the temp I set.
Regarding the Bars HGR, it is still working fine. I had fouling of the number one plug with coolant as well as oil in the coolant and vice bersa. All three problems are still resolved after about 2 months.
I did not change the engine temp sensor for the simple reason that I couldn't locate it on the car and heard it was a difficult task. Can anyone help me with info on this?
The coolant temperature sensor is in the coolant crossover, just to the right of and below the throttlebody. A hex head pipe plug with an electrical connector sticking out the back. www.rockauto.com , $7 - 8 ?
