Greetings all from a long-time reader, seldom poster ...
My temp gauge has been bouncing around for a while, and the vehicle runs hotter than it has in the past, electric fan kicks in a lot, blah blah blah…
I installed a CSF 3-row about 16k miles ago, and a new water pump, t-stat, radiator cap, hoses, and wp pulley about 20k ago. I’ve never replaced the fan clutch.
127k on the odo.
I’ve done a search on the boards here, and it seems it could be one of several things (or a combination).
I see that the heater control valve is sometimes the culprit, so I may buy one eventually, but I’m trying to do things one part at a time to figure out the issue.
I first bought a “Coolant Temp Sensor" (p/n 3300 4281), and right before installing, I noticed that there are two sensors under the hood that look identical to me: one at the t-stat, and one on the driver’s side on the intake manifold.
1) I believe the one on the manifold is the air temp sensor - correct?
2) my parts manual doesn’t actually show where the coolant temp sensor goes. I assume the one I bought threads in by the t-stat?
3) Also in my research, I noted that there’s another sensor called the “Engine Temp Switch” (p/n 5602 7012 or 5602 6710). I believe it’s located on the head or the block itself? Should I add this part to my list as I go through my process of elimination?
Thanks…
