    Have you tried and any 'Stop leak' ? It might be worth a try, otherwise
    the core will have to come out for a repair. Your overheating may be
    because it's low on antifreeze from leaking. The thermostat is usually
    the cause of overheat, has that been changed yet?

    Its leaking from the two rubber hoses that go down and out in the rear of the vehicle right at the pressed clamps. Last night the heat took a while to warm up then it only blew hot air for a couple minutes. There was also a bit of steam coming ut out the vents that fogged the windows.

    I noticed the temp gauge was a bit high last night as well then it spiked from hot to in the red

    Re fit those hoses with 'hose clamps' from the hardware store. That will stop it.

Antifreeze leak from rear of engine on pontiac grand prix

Rule out leak from water pump. What engine is it - 3.0 3.8. Could be intake manifold gasket. Have the cooling system pressurized, about 12 lbs. and look for leak, bubbles.
check oil for coolant in oil also. Possible head gasket leak.

Heater doesn't work, overheating engine, anti-freeze waisting fast??

The problem possibly could be due to a hole in the coolant system, i.e. a hole in a radiator hose or even the radiator. Loss of coolant will cause the heater to stop working and the engine to overheat. If it runs normally for a time, such as several days or a few weeks, and only after that time has passed the heater stops working and the engine starts overheating, then suspect a leak someplace. If it starts overheating after driving 5 to 10 minutes regardless of how recently antifreeze was added then, possibly the thermostat. It is staying stuck shut and preventing the hot coolant from leaving the engine and cooling in the radiator. The radiator overflow will probably have antifreeze pushing out the cover as a clue. However this can also be the result of a blown head gasket. As far as the fan, does the vehicle have an electric fan or is it driven directly by the drive belt. If it's electric, then warm it up to operating temp and open the hood and listen if the fan runs or not. It will start and stop depending on how warm the engine antifreeze is. If it does run, then the fan is fine, if not then the temp sensor that activates it is not working and needs to be replaced, or the plug into the fan may have become disconnected. If it's driven by the drive belt, then it should not be an issue unless the belt is broken, which would probably be affecting the power steering and alternator as well. If the vehicle has no power steering and the alternator light is on when running and it overheats, check to see if the drive belt is broken/missing. Check also to see if the water pump pulley is wobbly or loose. That would indicate a bad pump and would need to be replaced. Hopefully you just have a hole in a hose, and a simple hose replacement will fix it. incidentally, it's a good idea to replace both upper and lower radiator hoses at the same time, and the upper radiator hose is usually attached to the thermostat housing, so replace the thermostat at the same time too. Good luck.

I have an 1999 chrysler 300m an it has an overheating problem. There is also water all over the driver side floor (front n back) it is soaked. It takes about 25mins b4 it starts smoking. Can som1 plz help...

Typically if your leaking coolant inside the car, it indicates your heater core is split and leaking. Replacing the heater core is quite the job. It requires removal of the dash board and heater box. i replaced one in a 97 Cirrus at work last week and it was a 6 hour job. If your not mechanically inclined i would definitley recomend phoneing around for quotes to local auto repair shops and getting it done profesionally.

Two weeks ago it started leaking a thin, light brown fluid. This morning the heater didn't want to heat. This evening it started overheating whenever the car is on, but parked. What ever the problem, would...

It can be a reasonable fix, but there is the chance it is probably the heater core, which can be a pricey part on newer vehicles and unless you can replace it. labor will be kinda pricey as well. I believe these vehicles use the burnt orangeish antifreeze and that is what you probably saw leaking. I hope this helps please rate this thank you

99 Firebird still overheating after repairs and antifreeze

overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.

2000 bmw 528i overheating

The only way a heater core can cause overheating is if it's leaking and the engine is low on antifreeze. To check it for leaks it would help to use a cooling system pressure tester.

Pontiac sunfire overheating

I have your fix, Disconnect your Heater Core hoses and flush out the Heater Core or replace it. The coolant has to pass through the Heater Core before it gets to the Thermostat. GM designed the cooling system this way to speed up in-cab heating.
