You have all the classic symptoms of a leaking heater core. Not sure why you believe it to be on the left side of the truck but it isnt. It's on the passenger side.

    I looked it up online. It said my heater core is right behind my gage panel and steering wheel. I have heat and my temp gage is normal.

    I did some double checking after your response and here is 2 videos you need to watch on youtube. The heater core is lo0cated on the passenger side but the removal job is extensive. On youtube type in 7_hour_ford_heatercore_0001.wmv. After that type in Ford Expeditionh heatercore replacement. If you are wanting to do the job yourself these 2 videos are almost manditory. A leaking heater wouldn't necessarily interfere with your heating or engine temp until the coolant level dropped significantly. If your heater is blowing cold air it will take at least a gallon of coolant.

    You can if you like, it won't hurt. You can get it checked at most corner garages and probably some auto parts stores for little or no charge. When you are done changing it and everything is back together, leave the rad cap loose on the first notch and the heater on full blast for a couple days while you drive around. Keep topping up the rad and after a day or two the coolant level will stop going down. Then fill the rad and close the cap tightand top the overflow bucket to it's range. This will get rid of any "air locks" in the system.

SOURCE: windshield washer fluid hose is leaking behind front right wheel

I had the same problem. Reservoir would drain for no reason and I later found that the water was soaking the passenger side carpet and filling the wire channel under the doors. Tracked the problem to a barbed fitting behind the passenger side kick panel, just below the dash. The fitting connects the tubing coming through the firewall from the reservoir to the rear wiper/washer. The hose had come loose from the fitting (possibly due to freezing). I re-installed the tubing onto the the fitting and it has been fine ever since.

SOURCE: my 2000 ford f 150 is leaking antifreeze

This does sound like a heater core. To by pass it and be able to useyour truck, pull the two heater hoses off there stubs at the firewall (where they connect to the heater assy) and connect them together with the proper size barbed hose coupling and a couple of hose clamps. Now you need to replace your core and clean up the mess the anti freeze is making. If you Plan on doing this your self make sure you have a decent repair manual on hand for your truck.

Film on inside of windshield and a sudden large coolant leak. Could this be the radiator or what else?


Coolant leak is likely coming from the heater core or coolant line to/from heater core.

The film on the windshield is antifreeze.

98Volvo s70 heater core just replaced and now it smells like oil and there is an oily film on the inside of the windshield. Why?


That sounds like a fault in the cylinder head gasket. Check your oil for water, it makes the underside of the filler look like grey mayonnaise. Check the coolant for oil. And then you have a leak in the pipes to the heater core or the core itself.

Or is may be that when the heater core leaked, the coolant fell on oil or grease and it is drying out?

2003 Buick rendezvous floor board is staying damp. what could cause this


Have you noticed the smell of coolant inside the car? If you're in a cooler climate, does your defroster put a slippery coating on your windshield on cold days? If you answered yes to either of these, you may have a leak in the heater core in your HVAC system. Check to see if your coolant level is going down. If so, you need to have the heater core replaced.

If this is not the case, and you run your air conditioning often in a humid climate, the hose that empties condensation from your HVAC unit may be plugged (it is usually found low on the engine side of the firewall, on the passenger side). If you do not notice water dripping under your car with the air conditioner running, this may be the case.

When running heat or defrost, the drivers side of the windshield will fog up....no leaking coolant or antifreeze smell.


Many times there will be no smell or leak noticeable . sometimes it is just the difference between the inside and outside air .

I first noticed this smell of oder coming from my vents without the air or heat on ..then it started leaking antifreeze mixed with water they think could this be a leak in the hose or another problem ?


Step 1: check to see if there is any leakage of coolant under the car, if so it could be a leaking hose or water pump seal.
If not
Step 2: check to see if there's coolant leaking on the passenger side fire wall (inside the car) and to see if there is any fogging on the windshield when the defroster is running, or if there's smearing on the windshield, this would indicate the heater core is leaking and has gone bad.

How do u bleed the hoses from the radiator u can smell the antifreeze in the car need to know if it may be a hoses or something less


If you smell antifreeze inside the car then you probably have a bad heater core causing the coolant to leak inside you vehicle and giving you the antifreeze smell which will make you sick. If you windshield is all foggy and hard to clear and the right passenger floorboard is wet then your heater core is leaking.

You can drain the coolant out of your car by taking off the lower radiator hose. This will get most of the coolant out of your car. If you have a hose leaking under the hood you may smell coolant inside the car, but it shouldnt be too bad, if you have a leaking hose however it should be pretty obvious and your car may even be overheating.

Is there a way to know wheither its the water pump or a hose if you car is losing antifreeze? The car doesnt seem to be leaking when it is idle in the parking spot but when i come home frome a ride the...


it could easily be burning the antifreeze through a bad head gasket. if when warmed up the upper hose is quite stiff indicating the system is under pressureand you shut it off,even waiting until the radiator fan comes on and then right away turning of the key,wait and see iff anything runs out.the water pump would have to be looked at from below while the leak is ocuuring= reason must mechanics suffer a lot of burns. or with a sall extendable saft mirror. you could also loose antifreeze from a heater core leak but that would give a lot of steam on your windshield inside in the cold weather,or the carpet would be wet inside the car
