Question about 1996 Ford Mustang

1 Answer

Steamy car window

Heat was funky 2 weeks ago-took a while to do it's thing-smell of radiator fluid-funky heat but still heating-radiator fluid blowing out of cap,leaving a dribble trail sometimes-now leaking onto drivers foot a bit and steamy, really steamy when getting on freeway-no leak on passenger side-may leak radiator fluid from hose on the bottom of radiator-engine did get "cooked" a bit awhile back-car stopped counting mileage as well recently-bought a Heater Core bypass connector, not sure if that's the way to go,could be a blown head gasket doing the "using up radiator fluid method of death". Summer is near and it would be Great if I could get 6 Months more out of my car. Engine can be a bit "chuffy" when started until I gun it a bit. I bought an Air Filter as well and feel it wouldn't be bad to get a new Radiator Cap too.

I would not waste money on a radiator cap. The motor is shot ( probably a blown head gasket or cracked head) You probably will get weeks or until it blows up and the highway patrol puts you off the road with a hefty fine to boot.

    Hello Bill, I was wondering if bypassing the Heater Core would help at all. Drove again today starts up nice has good power was fine until the return home and started to steam again from upper heater vents, radiator fluid drivers side and passengers this time. Looked under car and fluid seems to be coming from firewall and is on undercarriage as well. No blast of radiator fluid top of engine, could this mean Heater Core (yeah) or Head Gasket (boo). I plan to bypass HC in the morning and I guess if it is a Head Gasket I can fix that but not a cracked Head.

    PS I pulled right off the Freeway, before-didn't really get on it and won't do that again unless it is just the Heater Core. No release of Radiator Fluid from cap, and top Radiator Hose was soft not hard. Thanks for the first answer.

    2 things to do Have a pressure test done on the cooling system to find the leak. Probably a bottom hose or the bottom tank split. As to the heater take a hose of the heater core and reattach it to where the other heater hose is attached to the motor/ head. Next have a compression test done to check for gasket or cracked head

    So, I bypassed the Heater Core and no more steam machine but as I was getting to know my engine I noticed a small hose that has broken off. The hose seems to have come with two female connectors attached-1 unit. It is the size of Perciatelli Pasta,funny but true. I have looked this up in my Chilton Guide and on line multiple ways. Went to auto parts store nothing matches- no hose no connector. I took one of the nipples in for matching got a hose that might work if I could adjust the nipple part-tossed it in my bag to work on when home, when I was driving off my brakes were super stiff so I put the nipple back on and brakes were back. The connector has a hole in it-followed the hose to the second connector which is on the passenger side. What is this hose and should I re-connect them? Thank you

    This hose comes from the top of the engine-driver side- runs next to firewall-connects to passenger side upper mid engine.

  • Bill Boyd Apr 02, 2014

    if it affected your brakes ,I am thinking a vacuum line to the brake booster. the other hose may be for the vent controls under the dash

SOURCE: Over heating

Check to see if your water pump is leaking radiator fluid through the weep holes, or maybe a wore out drive belt. good luck.

SOURCE: Coolant Problems

Hi there. It sounds like you have done the most obvious checks and I can assure you by-passing the heater core will have no effect. There are three possible causes that you need to investigate further and you will need specialist equipment for it - you either have a hair-line crack in the head or cylinder wall or it might be that the head bolts are stretched and therefore weakened and so need replacement. To help you identify these aforementioned possible problems, you might need a specialist fluid that you put into the cooling system which changes colour when combustion chamber pressure enters the cooling system, you need to contact your local Ford Dealer for this - but then you still have the three possible problems to deal with - cracked cylinder wall/s, cracked head or stretched head bolts. Hope this helps, Scottech.

On the 07 silverado smell comeing through the heat vent


If you're going through 1/2 gallon every few weeks - you've got a leak. Since you smell it from the heater vents - it may very well be the heater core ($$$) that is leaking. Usually, you'll notice that the windows will fog up heavily as the coolant is very hot / steamy once the engine has warmed up fully.

Look for coolant puddles under the truck to get an idea as to where it is leaking from. If closer to the front bumper - it's probably not the heater core - if closer to the firewall - it could be the heater core.

My 2008 ford edge when the heat is on blows hot


There are 2 things you should check. One is your radiator fluid level. The heater valve uses radiator fluid to heat the car, and it usually located above the engine, so when the fluid gets low, it's the first to lose it. The other thing to check is if your valve is operating properly. Being that your car is newer it's probably electronic. If you don't have a manual order one, it should tell you where to locate it, and how to test.

Only solution for this givin the circumstances, is that when he did reconnect the dash, he didn't reconnect the plastic tubing that's connected to the vents. Have you checked the radiator fluid or do you smell radiator fluid. Because also, sometime times the heater core is located under the dash against the firewall and he could have punctured it or disconnected that too. As for the radio, its very possible he didn't connect it right. He didn't have to take the dash off either to replace the radio. it should slide out of the dash pretty easy and they make an adaptor for the wiring harness.

Place car on a steep incline or raise front end up higher than the heater core. Now, add coolant to the radiator as needed, with engine warmed up. It sounds like the radiator is lower than the heater core causing an air lock and if that is the case this will allow the air bubbles to escape.

did you over heat the second time? or did the gauge go up with no over heat? alot of time in my expeirence severe over heat can destroy the temprature sending unit, causing false readings on your dashboard.

fill the radiator and start the car let it sit at idle for a while. then check under the car for leaks. try to locate the leak and see if its a job you can handle or take it to a shop also you said you smellled it when you turned on the heat. check the passenger side floor board and see if it's wety this could be a bad heater core. if you cant find the leak check your tail pipe smoke if it's real smokey and white this is a sighn of a bad head gasket or intake gasket

2000 GMC Heater Problem


I had problems with a similar truck,a 1998 GMC diesel after checking to make sure the control cables were operating the blend door and blowing the mess of the heater core,I replace the thermostats.Still no heat turns out there was a small amount of debris collecting in the fitting for the inlet hose at the thermostat housing after removing it and blowing out the lines the heat was fine.

NO HEAT


Les, it sounds like your blend door actuator has failed, it is a small vacuum operated diaphram up under the dash that controls a flapper that switches between the cool air and heated air. Good news is that it is an inexpensive part, bad news is pulling the dash out to get to it.
