Question about 2004 Pontiac Montana

1 Answer

My 2004 Montana had a rad leak and its now fixed . That was approx a month ago . The temp gauge runs steady all the time but when I slow down the temp from the heater drops , and when I speed up again it goes back to hot .Today after a short drive and I stopped , shut the vehicle off , went into the store ,when I came out and restarted my van the temp gauge was almost to the red . And it would not go down . It appears to have air in the system , because tonight when I left work to go home it ran the normal temp but done the cool air when stopped again . How do I make sure the system is bleed properly ?

Cooling problems can be hard to pin down.

Do you know if your electric engine fan comes on? If not they should, if you had the radiator fixed how was it done, new, rebuilt, or some fix a leak in a can? Driving an over heating car will ruin it, while the car is off and has sat long enough for the engine to cool, remove the radiator cap and check the fluid, do you have enough?

If the radiator was removed and replaced something may have worked it's way loose as in a wiring harness that runs the fans, most fans have a plastic safety pin of sorts that keep the fan harness from unplugging.

Another problem may be your water pump, since it's taken a month for you to notice any problem with the car I would not think it needs to be bled. Tho it might need to be.

Take the car to your local garage and have them look at it, if you dont do anything your cars engine can become damaged.

I do hope this helps!

I am a little confused here, you say the temperature gage is in the red but the engine is only at 140-160? Is that Fahrenheit?

I have a 200 Pontiac Montana and today it overheated into the red! Not sure why! I also don't have heat unless the RPMs are above 200. My fan don't kick on unless the air is on. 2 months ago I...


With the car running because it reduces the back pressure have someone that knows how to do it remove the cap from the radiator and see if the radiator is full, not the bottle but the radiator itself. If the antifreeze is not moving from the bottle to the radiator it will overheat. Not having heat unless you rev the engine makes me think the radiator is either not circulating the water or it is low.

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.

2001 pontiac montana heater is now blowing cold


You need to check coolant level in rad, when cooled down, and top up your return bottle to marked level.
Start by having coolant (antifreeze) ready, remove your rad cap, and top up the rad level, then start the vehicle, and turn on your heater (not defrost) . Let it run with cap off for a while, and keep an eye on level of the rad & top up as necessary, but leave an inch or so from top.Let it run & observe your guage while doing so, and when gauge gets to normal operating temperature, your rad fan should come on, run for a while then shut off for a while, then back on again after little while, and off again. Let it do this about 3 times, top off the rad as described above, put cap back on tight, and top up your coolant return bottle to mark on side. If your rad fan doesn't come on around normal operating temperature, and gauge heads too much towards hot reading, shut vehicle off, that's an indication that your rad fan fuse has blown, or relay, or fan itself is defective. If all works well & you now have heat, great, but keep an eye on your coolant return bottle level for next while to see if it keeps going down, and add as needed if it is. If the level in bottle continues to go down, you've got a leak in the system somewhere & need to address it a.s.a. p. to hopefully avoid bigger problems, but we'll get to that only if we need to. Do what's up above and let us know the results.

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

2004 impala coolant level


The coolant container (called the overflow reservoir) will be marked as to what constitutes MIN and MAX levels that should be in it. If it's low, add coolant.

As for what temperature it should run at, the gauge on the dash is just a general indication, but usually it runs close to the middle of the gauge's range.
