SOURCE: how to replace 2000 Alero cmp sensor?

On the 2.4 litre engine it is mounted on the cylinder head.
On the 3.4 litre engine it is mounted under the throttle body near the area where the transmission and engine meet.
Both sensors are held in place by one bolt.

SOURCE: 2001 Oldsmobile Alero Temperature goes high -

I would have someone pressure test the cooling system to determined if there is an external or internal leak somewhere as it sound like you have one or the other. An internal leak, such as a head gasket, won't show up as a dripping coolant but will cause coolant to be forced out of the coolant reserve tank in a kind of bubbly burp as the engine warms up while an external leak usually can be spotted by following the trail of leaking coolant back to it's source. I would suggest having it checked out as soon as possible as serious engine damage can result from even a fairly short time spent overheating.

Cooling fans run continuosly on 2001 alero


When the temp sensor fails, the computer will turn on the fan relay as a precaution to overheating.
Once you find the problem with the sensor you may also fix the fan problem.
If the check engine light is on you should also check the computer for trouble codes.

Simple fix, inspect the temperature sensor wire leads or replace sensor. It's located on the intake manifold by the thermostat housing. Good luck and keep me posted.

With a 2001 oldsmobile alero the temperature gauge shuts off , service engine light goes on but heat is still working, what's the problem


If by "shuts off" you mean goes all the way to the cold or no temp, then sounds like the thermostat is open and needs to be replaced. Could also be the temperature sensor and you are losing the signal. I would check to see the actual temperature of the engine to know the difference.

2001 Oldsmobile Alero overheating


I think you started out looking in the right places. Replacing the coolant, thermostat, relay and sensor are all fairly inexpensive.

I believe you either have blockage in the system (especially if you're using tapwater), or your water pump may be failing.

I would first either take it to a radiator shop and have them flush the cooling system out thoroughly, or else pick up a chemical flush kit and do it yourself. This involves more than just drain and refill.

If this doesn't work, your next step will probably be replacing the water pump. At almost 200k miles, it's probably about due anyway.

The fan must have gone bad. You need to replace the fan totally.

Changing a 2001 Alero Temperature Gage


Why change temp gauge, unless need be, what is the problem? Thermostat is the cheapest way to start!
