    when it gets 20 or below it gets real hard for the temp to stay up & it only blows warm air. Do i need 2 cover some of the radiator or will that damage the eng.

    same problem here, it's -25 celcius out. 2001 5.4 F-250. Replaced thermo and it only gets to the coolest reading on the temp guage. it never actually warms up completely. So it just blows warm air..

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..

1996 jeep grand cherokee blower works but no heat. I flushed heater core with hot water, replaced thermostat, and water pump is circulating. Vacuum line?


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

Can't get heat in a 1999 dodge stratus 2.4l


Hi my name is Allen!

I'm assuming when you say you replaced the thermostat your talking about the coolant thermostat under the hood on the engine.

If this is the one your talking about then lets move on to the repair procedure. If it is not then please let me know.

Let's make sure you have installed it correctly;

First; bring the engine to operating temperature, drive the vehicle if necessary. Next; grab hold of the upper radiator hose if it is hot, then grab hold of the lower radiator hose and if both hoses are hot you have installed it correctly.

Let me know what you find, then we can move on to the next repair procedure.

For further assistance contact me through FixYa!
