I drive a 9/2004 Escalade ESV for work (6 liter, 194k miles, AWD). Incidentally, I own a 9/2004 Suburban Z71 (5.3, 177k miles, 4WD). The escalade is what I need help with.
I have noticed that, in stop and go traffic, the escalade will go above 210 indicated temps, unless I turn on AC, whereupon the temps will go to slightly below 210. I am going to assume that this means that the cooling fans get turned on by the AC being switched on. I'm assuming they also should be switched on by a coolant temp switch, which apparently isn't doing so. Where would this switch be located?
I've worked extensively on E30 and E36 BMWs and I know where to find this stuff on them lol. I have no idea where to look for them on this escalade. I do not see them on the radiator anywhere.
