SOURCE: Male fitting on heater core inlet broke off in hose

RKmastertech is incorrect. That plastic fitting is seperate from the aluminum heater core and can be removed by means of a special quick disconnect tool, like OTC 6046. Rock auto has the fitting for $5 plus shipping, just for a reference.

Heater hose busted on my 2001 Montana van

If it's a heater hose, it will go to the firewall behind engine, where it connects to the heater core's fitting that juts out from firewall. Hose goes over that fitting. Heater hoses are fairly easy to replace, maybe not so easy on yours, due to lack of space. Drain the coolant before taking off hose, loosen clamps on it, then start pulling it off. Watch for a hose holding bracket that also needs to be removed before hose is completely free. Some do, some don't have such a bracket. Hire a neighborhood kid that works on cars to replace it, as sometimes that hose to heater core fitting can get stuck on tight, and if one starts yanking or pulling on it, you can break the fitting and will then need a new heater core-big expense to replace. Good luck and merry christmas in capital letters, lol.

Have a small amount of heat comming out of my 2002 montana van

Sounds like a blend door is not working.
The blend doors are controlled by small electric motors and direct air flow thru the heater and ac evaporator as well as the vents.
The blend doors would need to be checked for operation. Could also be an electrical problem elsewhere in the system or a blockage in the heater hoses.

2002 pontiac montana overheats

i would 1st check the thermostat, most overheating problems result from the thermostat sticking closed, and not allowing the coolant to circulate, while you are doing this, check the upper and lower radiator and heater hoses, to make sure that they are not collasping, also check the coolant temperature switch. this switch is normally located on the top of the intake manifold, most of the time, not too far from where the top radiator hose is connected. hope that this information has helped you.

The cabin heater has not been working for a couple of weeks (it used to blow some hot air but now no hot air) and now the car overheats at idle. Can you suggest a solution or a part to check?

first thing, change the thermostat. this should fix the overheating problem. Your hot coolant goes from the engine to the radiator core, then back to the engine. If your thermostat is stuck shut, you will overheat. try this first, and let me know, If you still have problems, We will get it fixed. hope this helps

99 Pontiac Montana Heater Hose assembly

What was the problem that you took the vehicle in for? Was it leaking?

Just like doctors, if you don't trust your mechanic move on and find one you trust. I often would be given a list of things that my customer was told they needed after getting tires (I didn't do tires back then) and Often none or maybe one thing on the list was really wrong. You have to be careful.

I need to replace the thermostat on a 2002 pontiac montana. I have a Haynes repair manual for 2001 pontiac montana with picture location of thermostat housing but I cannot visually find it even using a...

Where the upper radiator hose connects to the engine you will find the thermostat under that housing. You must drain the radiator and remove the upper hose. Then remove the 2 bolts holding the housing in place. Make sure to pay attention to which way the thermostat is mounted, spring up or spring down.

Heateer core leak

yes you can take the 2 hoses going to the heater core and join the 2 together under the hood so that coolant flows thru the hoses but not thru the heater core

No heat 2002 pont montana

Sounds like you either have a stuck thermostat or a clogged heater core. I would try replacing the thermostat first. If that doesn't solve your problem, there is one more thing you can do before having to worry about potentially replacing the heater core...

On most late model vehicles, the heater controls are vacuum operated. It's possible that one of your vacuum lines has either come loose, or has cracked. Try pulling off the dash cover and accessing the back of your heater controls. Find the vacuum hose that runs the heat dial, and trace that hose until you find your leak. If you don't solve your problem after replacing the thermostat and checking for vacuum leaks, then your problem will most likely lie in the heater core. Sometimes heater cores can be successfully flushed. However, more times that not, you'll have to have it replaced.

Like I said though, start with the thermostat. That's most likely where the problem is.

Hope this helps!
