SOURCE: no heat,ch.thermostat,water is circulating,blower goin strong .

Check the 'heater control valve'. This valve opens when u turn on the heat switch on the dash, so the hot coolant will flow thru the heater core and provide heat. So although the coolant is circulating in the engine, the valve controlling the flow to the heater core is stuck closed, or not working.

SOURCE: 2003 sable heater not working

Warm up vehicle. Then, from the engine compartment, grip each heater hose to check if they are HOT. Not warm HOT. If they are both hot, then the BLEND DOOR is stuck to the cold position. Access this thru glove box area.

If they are not HOT, then check radiator hoses for proper heat. If radiator hoses are not HOT then thermostat is stuck OPEN.

If they are HOT then there may be a restriction in circulation to the heater hoses and heater core.

you should have hot water on all rad. hoses when the motor is running at a norm. temp. the water is not going through the heater core like it should. you have cutoff valve bad low water are a stopped heater.try a hoter thermostat if none of the above are true.

SOURCE: water is not circulating in radiator. Engine is running hot.

sounds like the thermostat. the thermostat lets the water flow from the block to the top of the radiator.

I have gas central heating, one radiator doesn't get hot, the valves are open, the outlet valve is a Drayton TRV4, any ideas?


Does the non working radiator get warm at bottom of rad?, or do the pipes leading o it get warm?. If this is the case the rad is probably in need of leeding, to blee a radiator look at the ends of the radiator at the top. Older models will have a square protrusion that you need to turn, newer ones tend to have a slotted screw. Undo this until you hear a hissing sound, this is the air coming out, be careful though as the radiator fills back up with water you will need to be ready to close these down. Note the heating is best on when you do this, and combi boilers will need topping up so that the presure is between 1 and 2 atm. Hope this helps.

Trying to locate drain plug for antifreeze. Just had work done on my 1998 ford club wagon and need to drain water and add antifreeze.


As far as I know there are no drains in the cooling systems any more. I took the bottom rad hose off and drained my Buick. They say you should not put water in car rads any more.

Is car engine ok without thremostat


Have you considered power flushing the block to remove buildup of oxidation which insulates and holds heat? I assume you have replaced the thermostat with no results. There are opinions about operating with not thermostat. Some say it prevents the engine from reaching operating temperature and therefore is running ineffectually and won't meet emissions.

Heater just buts out cold air


Any leaks in the system(do you have to add water regularly?)? Check the heater control valve- it allows hot water to circulate through the heater core. Could be bad.

Hi Mark, I've just had the same problem with my 2007 Sante Fe. After replacing water pump, radiator, thermostat, etc, turns out it was the cylinder head gasket. No water in oil, but engine pressurises the water system, blowing water out the overflow. Cheers

My Toyota Hiace high roof with 3L Diesel Engine heats up. This was after the cylinder head was skimmed and had new valves replaced. Please help me. How can I stop this heating up? Cannon


Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..

there is a velve in the top hose look at the higest hose in the engine bay you will fine a screw or a nut in one of the hoses take the rad cap off and top the rad up fully run the engine up and undo this screw till the water pumps out it should let the air out first, when only water comes out the engine is bled free of air, keep the rad uped up at all times

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.
