first suggestion would be the head gasket which Montana's are notorious for having problems with, followed closely by a crack in your cylinder head or engine block
small amounts of water coming from the muffler is normal but if its antifreeze its not
The gas tank in my extended 2000 Pontiac Montana is 25 gallons. I would imagine the 02 is the same.
the struts are probably bad and need to be replaced. you can get them at almost any auto parts stores
A common problem with the Montana is the power steering pump.
water temp sensor wire grounding out could cause this problem.
Open the hood. With your left hand, reach out and down a little. It's right above the water pump pulley. If it were a Bear, it would bite you. :p
the steering wheel..
Possible starter or starter solinoid? more info would help
Low coolant Water pump not working properly Cooling fan not working Thermostat not opening fully Radiator plugged or dirty Check the radiator fan.
Could be the heater core leaking or the windshield needs sealant.
You more than likely have a bad water pump. With the car running, open your radiator cap and see if the water is circulating through the radiator. If not, then your water pump is bad. Hope that helps...
NO! the Montana is a front wheel drive minivan and the firebird is a rear wheel drive, even if they were both rear wheel drive for some reason, the firebird engine would shred the wimpy minivan trans and it would be just wrong to put a minivan trans in a firebird.
