Question about 1986 Ford Bronco

1 Answer

No heat or defrost

Car has been sitting for over 2 years. The heater core was replaced about 4 years ago. Thinking it might be the thermostat. What are your ideas? Also, where is the thermostat, on top or bottom of the radiator.

Thermostat is not on the radiator. It is in a housing on the intake manifold at the engine end of the top radiator hose.Heater controls on that truck may be vacuum controlled or cable controlled You need to check and make sure that the heater lines are open and water is flowing through them.

Check for a clogged or defective radiator. The inner parts you can't see could be the source of the problem.

Whats the problem if blender is gone in 1998 GMC Sonoma


Are the controls for opening the heat functioning? Opening the heater core and allowing fluid to pass through the core would be where I would look. For instance you could remove the outlet hose from the core and see if water is passing through. Thinking it might be a clogged heater core. How about the heat gauge on the dash? You said the hoses were hot so guess the engine is reaching proper temperature. If you have A/C can you get warm air when you use defrost? If so, the heater core is OK. Conclusion: My first thought is the heater controls are not working properly but if they are then my second thought is the core itself. Hope this helps you.

1994 v6 Firebird I have overheating issues recently, replaced hoses, cooling fan and radiator. It seems to be circulating from water pump. I do not know which way to turn now, no leaks that I see only when...


Water pump might not be flowing fast enough. Be sure fans actually turn on instead of just sitting there. Change oil. You could have something in the motor causing excessive heat. Piston friction or cam problems ect. Try a synthetic oil.

Will a flush and fill of my radiator help with the fact that my heater isn't working. it is not the thermostat and about 2 years ago i had the same issue and the repair guy said there was a bunch of stop...


I have had a 4 cylinder s-10 and a v6 sonoma Both at about 100 thousand the heat stopped working. It's the heater core in the dash never put stop leak in any thing it's a sure fire way to clog up your whole system in my experience. A patch is never as good as a replacement. I know it;s a long job but do it right so you don't have to be sorry later. Another work around that i did for a while i went to wal-mart and bought a 9 volt heater that you can put on your dash to defrost your window considering a heater core will take 2 days to remove and replace !

1999 Taurus-NO HEAT-replaced thermostat,flushed heater core,still NO HEAT,ANY SUGGESTIONS?


Sounds like the problem has to be the valve is not opening and thus not allowing the hot coolant to enter the heater coil. Manualy open the valve (engine firewall) and see if heat is present. If this works check your cable from the dash switch as it isn't working the valve properly and needs replacing.

Not heating inside car


One or more of:

1. Your coolant level is low
2. Your thermostat doesn't close and needs to be replaced
3. The valve from the cooling system to the heater core is stuck
4. Your heater core is clogged
