1998 peugeot 406 heater gets warm but not hot


This may be a thermostant or a plugged heater core, locate the hoses going to the heater core in the engine compartment, feel both of them and see if one is a lot hotter than the other, if so then you may need to flush the core with a water hose, the other thing would be if the hoses are luke warm then the engine thermostat mat be stuck open.

1999 VW Passat heat not working


Could be your thermostat... If defective, it will not allow the engine to heat up. Take the coolant cap off before you start the car when it is cooled off. start the engine and let it idle, look at the coolant. The coolant should not be flowing or moving right when you start the engine, if it is, the thermostat is bad. If you dont have enough coolant and you see it is low, this may also cause the heater to stop working. Someone may have by-passed your heater coil, check that. Sometimes when a heater coil leaks, people will by pass it so that they can continue to use the car or they cant afford to change it. It should be located on the passenger side under the dash or on the firewall inside the engine compartment on the passenger side. Another thing could be your climate control which is a fancy name for the heater controls on your dash, sometimes the switches become defective and will not operate the heater.

Where is the thermostat located at on a 99 2.8 passat and how much stuff do you have to remove to get to it because it is running hot.


follow the big radiator hose from the top of the radiator to where it connects to the engine. at the end of the hose is a metal housing usually held on by three bolts remove the bolts and pull away the housing the thermostat is located just inside.

I dont have any heat and i need to know how to replace the hearter core, however the windows aren't fogging up so maybe its the thermostat


the only way you should have to replace a heater core is if it leaks or gets plugged up. When motor is hot feel the two hoses that go to the heater core. one should be fairly hot and the other should be the same but if one is just warm then follow hose and locate a flow valve and check for operation. OPening and closing with control hot /cold knob. Check coolant level in radiator while cold as well as fill reservoir to full when cold. Also remove radiator cap when cold and warm truck and check for flow of coolant. if lower radiator hose is hot hot hot and upper hose is cool then thermostat may not be opening properly, or thermostat is stuck open not building heat. You didnt mention if truck was overheating?? If its not i'd check for the flow valve operation, if it is i'd make sure coolant levels are full and waterpump is working.

Locate n change thermostate heater blows but not hot


if the engine is running fine, then the thermostat is opening and closing correctly and changing it will not fix your heater. the core is plugged or the blender control is letting in too much cold outside air.
