engine light

91cobra5.0 · July 27th, 2008, 01:12 AM

i put a 160 degree thermostat in my car, would it through an engine light if it wasent reaching a high enough temp???? it comes on after like 10 mins then goes away as the engine gets hotter

jtyson8602 · July 27th, 2008, 01:19 AM

shouldn't matter what size thermostat you put in.

ryans88gt · July 27th, 2008, 01:32 AM

could be the ECT sensor going bad. 160 should be a good operating temp, no reason to throw a CEL.

91cobra5.0 · July 27th, 2008, 09:59 AM

ECT?

JBIGBOOTSY · July 27th, 2008, 12:14 PM

Engine Control Transistor. It's in the intake on the front driver side of the lower., there is one on the heater tube on the lower intake on the passenger side too.

91cobra5.0 · July 27th, 2008, 12:23 PM

heater tube?, and is it twords the front of the lower or the rear, like is it under the upper so i cant get to it if i dont pull the upper

wraitherx · July 27th, 2008, 02:41 PM

yeah to some extent. cooler operating temperatures do affect your performance.

It will run a little richer.

would that be such a bad thing at a higher altitude with lesser oxygen? and would it be richer across all cylenders?

Yes it will be richer across all cylinders. It will probably do more harm than good at high altitudes.

AdderMk2 · July 27th, 2008, 09:47 PM

you car will not reach full operating temp, and you will not be driving around in closed loop

91cobra5.0 · July 27th, 2008, 11:57 PM
