There is a leak somewhere in your anitfreeze tank. This problem needs to be fixed. Check for leaks in the tank or anything that attaches to it. You say it is on your tire? Look in the wheel well and see where it is coming from. Hope this helps! Please rate 4 thumbs up!

I have a 1997 grand cherokee and i got a new heating core put in but sometimes when the heater is on you can smell antifreeze.


If you smell antifreeze, there is a leak. it may be just coming from a hose connection to the heater core. Have them recheck the connections and inspect the cooling system for a leak. It should be evident when inspected. Also, what your engine temperature when operating the Jeep, If the coolant is low,from the leak,you can start to overheat.

Every time i turn on my 99 sebring it over heats allmost instantly what do i look for


First, is the coolant level where it should be? If not, add until it is.
Second, do you hear a bubbling sound from under the hood? If so, you've got a blown head gasket with exhaust gases leaking into the cooling passages.
Third, you may have defective temperature sending unit.
Let me know if this helped.

Antifreeze filling sparkplug boot.


well if antifreeze is filling the spark plug boot area there is only one way that can happen,,,the cylinder head must be porous and leaking coolant thru the aluminum casting into the spark plug boot area, youre gonna need a new cylinder head,,,,you could try a ginger root tab or like a radiator stop leak first if it not a major leak,,,thats might by you some time,,,but sometimes that stop leak stuff blocks up the heater core and then you have no heat,,,i owuld just replace the head,but if moneys tight risk the rad stop leak and maybe youll get lucky

Heater Problums with the smell of burning Antifreeze.EXTRA Detail


Hi!

I really feel you could be losing a small amount of coolant from the heater matrix/core.

It appears we have an Air lock scenario due to this and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
Also with your temp gauge reading 1/2 this is normal, possibly the core is blocked or as already suggested leaking, a Radiator sealing additive might help BUT it may be the cause of your cold/warm air?
TOO MUCH SEALER blocking the Matrix/Core?
I hope all this helps!

There are a few things that you can check. The freeze plugs that are generally round, can sometimes leak but they usually go out completly and pour antifreeze all over. Another thing to check is all of the hoses and where they connect to the radiator. If none of this is working, please include a better description of where it is leaking from.
