SOURCE: Temperature sensor problem?

There are 2 different circuit that control the cooling fans.
The engine controller turns the low speed fan circuit on to control temperature and turns on the high speed fan circuit if the engine and A/C is running.
It sounds like your low speed fan function is not working.
Find your fan 1 fuse located in the under hood fuse panel and make sure it is not blown. If OK go to next step.
Find your fan 1 relay located in the under hood fuse panel. Find another relay in the fuse panel that matches and swap the two. If the fan then works you know you have a bad relay.
If both are check good, let me know and we will go from there.
Below, I have attached the wiring diagram for your cooling system, hope it helps.

SOURCE: cooling fan not working

The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.

SOURCE: temp gauge and gas gauge not working

I had the same problem with my 2001 Pontiac Montana and the intake manifold gasket. This is a major problem with these 3.4L engines, if you are in the states I'm pretty sure there is a class action law suite against GM for this. I had my manifold gasket replaced and it was about $1000 CAD. You need to get your vehicle looked at right away as this could cause major engine damage, coolant will leak into the engine and soon enough you will be replacing that too. Good Luck

SOURCE: Timing off on Pontiac Montana wipers

On top of the window motor there is a timing cam -- there is a little tab on the bottom that is most likely broken or bent. You need to replace the cam.

2001 montana cooling fans not coming on


A pontiac montana ? There are three relay's that control your cooling fans ! unplug what sensor ? The engine coolant temp. sensor is an input to the PCM - engine computer . When temp. reaches 213 degrees the PCM energizes the relays , depending on low or high speed . Using a scan tool to see if the PCM will turn on the fans an checking engine coolant temp.data is the right way to diagnose this . Relay Driven Dual Cooling Fan Diagnostics

Trouble codes p0118 temperature po118


code p0118 refers to engine coolant temperature (ETC) sensor ---circuit malfunction===causes---coolant thermostat---wiring open circuit/short to positive---wiring short to ground---ground wire defective---ECT sensor.. The temp gauge works off a temperature sender unit separate to the coolant sensor and if it is reading 100 then it indicates an overheat situation in the engine . Probably why the engine light is coming on. As the thermostat is in the list of causes I would replace it as a precaution. The coolant sensor is what tells the CPU to turn on the electric fans to cool the radiator

No temp gage on montana van. fan starts on start up engine seems cold after it should be hot


Check the heat gauge sending unit. Or "engine coolant temperature sensor" as they call them these days. ECT. It should be somewhere near your thermostat housing. I hope that's the problem. Good luck.

Heating problem


Yes that is cool if it's correct. 195 F is approx.as low as you should have. I'd change it. Be sure to run with cap off, and heater on (not defrost) while refilling system. Wait for rad fan to come on 2 or 3 times before you put cap back on, then add coolant to return bottle as needed. Make sure rad fan only comes on when up to normal running temperature. If it runs all the time, it may be causing low coolant temperature too.
