I have changed the radiator cap, replaced the thermostat, checked the water pump, and hoses. My 1998 Honda Accord LX still gets hot. When I check the wate and antifreeze, it is still full. What should I do now?
Have you bled the thermostat? Remove your top radiator hose from the radiator. Get some water, because you need to pour to water down that hose back toward the thermostat housing. Before you do that find the thermostat bled plug located on the housing. unscrew the plug and pour the water into the hose. when water start coming out of the plug tighting the plug. Replace the radiator hose and top radiator back off with water.

You would probably be better off replacing the belt and pump again since the labor would be next to nothing. I would want to test the cooling system for exhaust gas and try to verify the head gasket is actually leaking next. Are you loosing coolant into the cylinders ? There may be something else causing the engine to run hot such as exhaust problems.
no it might have problem inside the engine also the check light should lighted get it diagnose to find what is the problem overheating really problem on the engine might be also thermostat issue have it check specially with check lights are on
"Will start but will not turn over" What the hell do you mean by that ? If you can start your engine then check the upper coolant hose, this one should get hot first, then, after thermostat opens, the lower coolant hose should start getting hot also, check both hoses every 30 seconds wile the engine warms up to operating temp. If any of the above is out of spec then I would change your water pump.
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.
have u replaced the radiator and hoses? Thermostat could also be stuck open. Water pump could also be your issue. with motor cool and of remove radiator cap(cap may be bad as well) top-off fluid and start car check for fluid flow with flashlight. Water pumps typically leak from what is called a weep hole when the shaft seal fails. Yours will be located under the timing cover (drivers side) running of the timing belt.
Hit me up after u have check on these.
Yes, there is a "bypass outlet" coolant hose that connects from the water pump inlet pipe (metal pipe that runs from back of water pump along engine block to lower radiator hose) to the intake manifold.
I am not sure about the "black box" - not enough detail.
if you go to your local library most do carry the manuals and you can copy the info you need.
difficult.. yes. extremely difficult...no
if you decide to do it make sure you use 1/2 drive breaker bar on crank pulley if your lower timing cover cannot be moved far enough to access the water pump mounting bolts. also make sure you don't turn the timing gear when removing the belt or replacing it.
hope this will help you.
