    I have the same problem and I had my van looked at and there is a leak, don't remember where, but there is. I am just keeping the coolant level in check till I can get ti fixed. I was advised it's expensive to fix.

Bad News. I recently had the same type of smell ( no leaks or puddles either) coming from my van and had to have the intake manifold gasket replaced due to the Dex-cool issue. It appears GM installed an inadequate/substandard gasket when they built the van. My van only had 65,000 miles on it. There's a Dex-cool settlement you could have applied for but repairs had to be made by May of 2008.

This is the only real complaint I've had with the van.

How to get the battery out


The battery in the 2003 Pontiac Montana is located in the engine compartment on the passenger's side just behind the headlight assembly. Changing the battery can be a little challenging because the Pontiac saw fit to bury it below several other parts in the van. The under-hood fuse box sits directly above the battery and a cross brace runs over the top of it as well. Dealing with both items is not complicated but does add time to the process.

Overheating pontiac montana shooting out cold air from heater


Get the radiator and heater core, hoses and thermostat replaced. Also replace the mixing valve if needed. A radiator shop could give you an estimate and diagnose the problem better than I can online. I hope sincerly that this helps.

Antifreeze/water leaking . puddle underneath van already got new thermostat, radiator is full overflow box full. can't see where leak is coming from. either from below or above view is blocked by other...


May not be either. Does the van run hot? If it doesn't then the coolant when it is heated is going to the overflow reservoir and if that fills up then out the overflow line to the driveway or the garage floor but everything is O.K.

Hello Burger.

The engine control module is mounted on the left front under the hood to the left of the air filter.
It is under a plastic cover.
Hope your repair goes well for you.

Brakes went completely out, not the brake pads


Do you mean the brake pedal goes down to the floor, and doesn't stop the van at all? If that is what happened, check the master brake cylinder reservoir under the hood, on the driver's side of the engine, at the 'firewall', which is the engine compartment metal wall that separates the inside of the van from the engine compartment. Is it low, or empty? If the fluid is down, there is a leak somewhere. This must be fixed before you can drive it safely. Check under the van for wet areas, especially at the back side of the wheels, and any puddles or wet spots on the ground under the van. Let me know what you find, I'll try to help further.
