Question about Ford F-150

1 Answer

My truck is losing coolant but havent noticed any leaks on the ground & nor is it running hot unless completely empty on coolant, of course. And when coolant is low I lose heat.

Now if I'm moving I have heat for the most part. But if I stop I have no heat. Where is this coolant possibly going?? Plus it is winter & I need heat. Thanks

Since the coolant is disappearing, there is a leak and the operating controls for the heater are probably working. Its the lack of coolant which is affecting heat levels.

Go to a Website called aboutautomobile.com and look up your year,make, and model of truck. They have a section about Technical service bulletins, consumer complaints, and recall info. If you find a TSB number there may be a course of action for you to take.

If the head gaskets are leaking into the engine, it can cause this problem. See what is available for fixing this the right way. If nothing is helpful you can try sealing compounds. Because these glue-like compounds get into every area the water reaches, its a toss-up over whether you will clog something up. But you get what you pay for, the more expensive types can work.

What you are trying to do is save from opening the engine and an expensive repair bill.

    Well it's a new engine I got thru Jasper Engine & is under warranty. I was just what is causing this. What a mess... lol Thanks

    Was the original engine damaged because of overheating? There has to be a reason for this to continue; it would be some part that was not replaced.

    No, it was lack of care from previous owner. But took it to mechanic & guess what it was... A few of the clamps on a few of the hoses wasn't tightened down enough. Cost me $52 ugh lol

Losing antifreeze but not on ground not in oil


Generally speaking, if there are no external leaks, odds are the engine is burning the coolant out the exhaust pipe due to a leaking intake or head gasket.

Losing coolant, no leak, not overheating


That would relatively normal usage. Coolant is 50% water so repeated heating to near boiling is going to have an effect. Unless you are adding by the gallon, I wouldn't worry.

1998 cadillac deville leaking coolant, temperature was around 196 and when leaking started temperature has gone as high as 225, what is causing this problem?


This most certainly sounds like a water pump issue. The thermostate is located inside the water pump housing and if the pump is bad you'l lose fluids and need to add every day or so. The temp guage will run hot and often the heater won't warm up. You have even notice fluids on the ground below the front passenger side of the car. Try getting a pressure test first before replacing anything. That's a good place to start the diagnosis.

My 2001 Ford Windstar van seems to be using alot of coolant daily


Possible coolant leak on hot engine parts causing it to evaporate as it leaks. That would definitely invade the cabin air. You would need to carefully check under the hood with the engine warmed up and running.

Also could be a headgasket failure between coolant channels and a combustion chamber. This latter problem sometimes shows itself as vapor at the tailpipe after there should be no more visible. You may also detect the odor of coolant there too.

Since you are not overheating, thermostat is likely not the problem. Chances are you have some seepage at either an intake or head gasket that is dripping onto a hot pipe when you stop. Leak may be so small at this point that coolant loss is barely noticable. but if you look carefully at all head/block parting lines and check all obvious connections that could leak, you will find the problem. Any white smoke from exhaust?

I hate to tell you this but its possible...

You have a leak. Look around on the driveway and try to determine if you have an external leak as opposed to an internal leak. If you see no coolant on the ground, suspect a blown head gasket. Do not continue to drive this car in this condition. If it does indeed have a blown head gasket, serious engine damage will occur.

Check your exhaust for white smoke. Chances are good you have a blown head gasket and coolant is leaking into the engines combustion chambers and is essentially burning off. Also check your oil, if it looks like caf mocha, this will confirm coolant is leaking into the oil via the blown head gasket
