Buy a 5/8" hose splice, disconnect the hoses going to the heater core (wiggle and twist them off instead of just pulling) Be careful not to trash the $18 heater control valve that is connected to one of the hoses, the plastic may be a bit brittle.

Bypass the heater core by splicing together the two hoses. That ~1/4" hose that tees into the heater hose carries coolant from the engine in case you were curious.

Your heat and defrost won't work, but at least your not breathing ethyl glycol fumes.

My antifreeze is leaking somewhere but i am not sure where i dont see anything on the ground but i can smell it burning or something. so i would like to know what the problem could be. and possibly the...


Do you smell it from inside the cab? That could be a leaking heater core and it running under the carpet/mat.
If its a pinhole leak it could be spraying when pressure is built and just burning off so there is not puddle.
With a pressure tester I could not find a leak in a Ranger. Once it was running and pressure built I had to turn a heater hose to see a pinhole leak spraying coolant.
Look for obvious signs of discoloration. Could be leaking from the radiator tanks or core. Could also be coming out the water pump's weep hole and only while its running.

If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.

It isn't heating correctly and i smell antifreeze. How do I check and replace a heater core in it?


If your heater core was leaking you would have antifeeze coming thru your vents and putting a greasy film on your windshield. You would smell antifreeze the stongest if it was leaking onto a hot engine part. low antifreeze will cause bad heater performance, I would check by the thermostate housing, and the water pump for leaks

My ford truck smells of antifreeze?


You have a bad heater hose and it's being pulled in the cab, if your ucky. Otherwise you will have to pull out the heater core and replace it. A new one runs about $75.00 and can be bought at any auto parts store if you wan to try this on your own post here and I will give you the proceedure.
