High Engine coolant temps, possible sensor?

[dsm2nr]

yea, i was wondering if a bad coolant temp sensor will cause the reading to be high. I checked the fluid, and the coolant is full all the way. any ideas.

what about your thermostat?

[Leung]

do your fans work?

[dsm2nr]

thermostat works and was replaced, and the fans work too.

get a coolant tester and test your coolant?

[xfactortype1]

its the coolant temp sending unit switch..i.e controls the guage hot cold in dash. when it goes bad it usually read false hot. new one for under ten bucks at autozone.

Pressure test the system...Are you loosing coolant anywhere? If you replace most of the stuff and its working I would check the sensor. If you have a DVOM you can test the sensor but I dunno the specs right off the top of my head.

yea, make sure you're not leaking coolant somewhere. my car was doign that yesterday because after my swap someone forgot to clamp down the hose to the iacv and it started overheating.

[dsm2nr]

it's not leaking any fluid, I checked the level and it was full. where is the sending unit for the coolant sensor? I'll try and replace that and see if that does it. thanks

you have a H22 or F22?

[cp[mike]]

temp sending unit its a small single pin connector on the side of the head under the distributor, it has a red wire.

[dsm2nr]

I have a F22. I thought that's where it was, cp[mike], thanks. So can I go to autozone or somewhere and get the harness, connector, or sensor? Does the thing just unscrew from the nut that it's attached to? IDK how these work, sry for the ignorrance.
