    Can you feel heater hoses when engine warmed up, where they go into the firewall to attach to heater core from engine? If one hot & other quite a bit cooler, there's something restricting the flow of coolant. If both pretty close to same temperature, then blend air door in duct work under dash or wherever located on your particular vehicle, is probably stuck or not functioning properly.

If engine temp is normal after running awhile. i would try to flush the heater core.(disconnecting the heater hoses from engine and flushing separately) ford cars and trucks have a "brown coolant" problem and the coolant will eventually clog heater core.

disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec

Engine warms well, heater fan blowing well, but very little heat comes into cab


It could be one of two things.
1. Bad thermostat. Your thermostat is pobably not opening when the engine warms up. Install a new thermostat and you should be OUT OF THE COLD. If not,
2. Your heating core and radiator is probably clogged. One way to solve this is. Flush out your radiator with radiator flush kit. Pease read your owners manual, (YOU NEED TO USE A SPECIAL TYPE OF ANTI FREEZE). If you use the the green color Presotne anti freeze, It will gradually corrode through the linings of your radiator. And the green color prestone anti freeze will blow out the radiator. So read your owners malual ( I beleive it says you have to use Dextron Anti Freeze ( Pink Color).. Replace your thermostat and flush out your radiator. Then refill your radiator with dextron anti freeze. Also make sure the anti freeze resivor is filled to the proper level.. Once you do all of this, YOU DEFFINITLY WILL BE IN HEAT.. YOU CAN DO THIS YOUR SELF ( iT WOULD TAKE ME NO MORE THAN 1 TO 2 HOURSFOR ME TO DO THIS IN MY DRIVEWAY) OR YOU CAN HAVE THIS DONE AT ANY QUICK LUBE LOCATIONS... HAPPY MOTORING

Just flushed rad heater core and block because i had no heat. flushed the system filled with new antifreeze. my temp gauge will change from 150 to 210 I have heat then i dont


Replace the thermostat. I have had bad luck with aftermarket thermostats on this particular year of GM/ Chevy trucks.They tend to stick closed and then fully open, thus causing the temp to sort of surge hot and cold. A good thermostat will slowly open maintaning a good consistant temp. I would recommend spending a little more and getting a GM thermostat.

Start with Flushing out your cooling system. Flush it out with Preston Radiator flush, you have your preference of ether the super flush which takes 3-6 hours or the 10 min flush which is good if you don't have the time to flush out your cooling system.

After you have flushed out your cooling system, replace your thermostat and you should be good for another cold winter driving. What happens is that after a few years of the coolant not being serviced, the coolant crystallizes and clogs up the heater core and radiator causing poor circulation. Poor circulation will cause poor heat and or overheating issues to the engine.

Before you go through all that inspect to make sure you have the right amount of coolant in your cooling system.

Good luck and thank you for using fixya

Over heating, thermostat replaced, radiator, engine, and heat core flushed, no water in exhaust.fans working, water pump flushes water thru.


You may have air in the system. Let the engine run with the radiator cap off until the thermostat opens. Have someone then get in the truck and bring the rpm up to 1800 to 2000 rpm and hold it there for 15 to 20 seconds while you top off the system with coolant and put the radiator cap tightly back on. Then bring the rpm down to idle and road test the truck. DO NOT BRING THE RPM BACK DOWN TO IDLE UNTIL THE RADIATOR CAP HAS BEEN INSTALLED COMPLETELY. I suggest replacing the radiator cap at this time also.

Bublling in the thermostat housing and very hot upper radiator hose


I recommend flushing the radiator thoroughly if not done recently. there seems to be some sort of blockage in the radiator at this time. if you get lots of metal fragments that are flushed out during this flush, i will then recommend a rebuild on the radiator or replacement of the radiator. make sure the cooling fans are cycling on time as well.

Running hot


Did you get a new one? or used and yes you need to replace thermostat , also flush radiator and system repeatedly as your heater core maybe becoming blocked buy some radiator flush and read directions! follow heater hose to engine, thermostat will be in the top line
