    check behind the alt, under the heater hose, you did not state which engine

    ecm uses it to calibrate open loop air/fuel ration, also cold temp startup

    You can change out the coolant temp sensor without draining the prestone, remove old CTS, quickly get it out of the way then screw in the new unit.

    Behind the alt. I ain't messed with it yet but I know now what to do lol. I struggle with this stuff, I love mechanics and I've always wanted to understand more. My biggest thang is I'm always havin to do the thangs I need to on my truck when I get the chance cause I'm a 24/7 mom to a disabled kid so I'm kinda slow at gettin around to everythang or atleast that's how it feels to me haha. I do want to know some advice and it may sound crazy but it's just how it is, so I know alot of basics when it comes to vehicles in general but what I struggle with is understandin everythang. Alot of times I find myself researchin and I feel like I'm suddenly readin another language and it don't stick. I want to understand exactly how everythang functions and what functions what but I can't never find anythang that's really helped. Any advice?
