When I drive the temperature seems to go up. But if Im idling in park it never moves. What could cause this? Ive changed the timing belt, replaced the water pump timing belt, water pump, thermostat, hardwired the fan, and changed the radiator. Im driving a 1990 Honda Accord.
What does it mean if the car only heats up while im driving?
sounds like ur heater core is stopping up and the faster ur motor runs the more pressure u make so try reversing ur hoses on the core

Maybe it is the transmission that is getting hot and transferring heat so it seems it is coming from the engine.
Your heater core may be partially clogged or you may have an air pocket in the cooling system. Check the blender door in the heater assembly as well.
good luck........
depending on how much it goes up is the key. Check with spec for the cooling system in your veh. If the temp goes up then the fan and stat open the it goes back down this is normanl. If it goes to high start with changing the stat and radiatior fluid.
Make sure that you are not driving in low gear.
well it's happening because the engine is creating heat faster than it can cool itself off. I say take it into a shop and see if another problem is preventing the coolant system from working properly.
It could mean your driving to fast! No it could really mean your out of radiator fluid, your belt on your fan could be off or lose, or your water pump might be going out. A simple temporary solution is to drive with your heat on, on full power
OK if anyone says transmission they're lying its the heater core or radiator that's doing that
First of all you shouldn't have hard wired the fan. Not trying to be the bad guy hear but its set up that way for a good reason. If it is going up while driving it is supposed to but only till about half then the fan will come on but since its hard wired it is all ways on therefore it shouldn't go passed half. If it does and this happens within say five min. sounds like a thermostat issue even new ones go bad and make sure its installed properly. If all the parts have been changed and all seems to be in order the only other thing is a blown head gasket.
