Why is a 1994 Honda Accord LS still running hot when idling after the thermostat radiator and both hoses were replaced?
On a Honda there is a bleader valve (similar to a brake one) on the gose neck. Start the car let it get warm and open the valve and let out the steam. As soon as water sprays out tighten it back up and it will work fine. You have to do this because the radiator sits lower than the engine.
Replace the radiator cap. This is a common problem on any vehicle. The cap is designed for a specific pressure(13-15 lbs on average). The cooling system is under pressure, so when the cap is bad it fails to maintain that pressure, effecting the flow of coolant.
You could have a blown head gasket.
of course it could be a lot of things... check the coolant sensor -- screwed-into the very bottom of the radiator. if the car was in a front accident or the radiator was replaced, the sensor (i think that's what it's called) might be bad. replaced the one on my old 86 accord lx, and that did the trick! good luck.
I'm in a similar predicament, however I'm replacing the sensor first, then the Fan Relay located in the fuse box (Becuase I've noticed my fans don't turn on at all !!) , then the thermostat... and if those don't resolve the problem, then I'll replace the water pump. Remeber replace the simplest, least expensive first.
Check the coolant temperature sensors. On 4 cylinder 1990s Accords, one is located in the passenger side end of the cylinder head, near where the upper radiator hose comes in on the front. It's under the distributor and is a little hard to locate at first. This sensor tells the engine computer what is going on, and if it's bad, it can fool you in to thinking you're running hot even if your engine is fine, and it does affect the way the engine runs.
Also check the fan relay, located behind the glove box lid, and the temperature sensors (that operate the fan) located on the radiator.
1994 Honda accord and the radiator was cracked and i replaced it and bled the air out It is now running hot when the car is in idle and it doesn't seem to run hot when i am driving?
Had the same problem on my 1991 accord. Replace the thermostat, gasket, and radiator cap. Also, get a gallon of coolant if your current coolant has been in there for more than three years. The thermostat is in the engine block. Simply drain coolant, remove the radiator hose from the engine - the hose that goes from the bottom of the radiator into the engine. There may also be a small spount that bolts into…
Replace it with the exact same temperature thermostat as the one you removed. Do not run the engine without a thermostat. The thermostat is required to keep the engine running at the optimum temperature that will give the best performance and mileage. If it is overheating running it without a thermostat is not the solution.
Dieseling or "Run-on" occurs when the engine is so hot that the fuel in the engine ignites without the spark plugs firing. On newer cars, like this '92 Honda, there should be an anti-dieseling valve that will turn off the fuel. That might have failed and will need to be replaced. After your engine has cooled, check the coolant level. If the coolant is too low, it can contribute to the engine overheating. If the…
The thermostat for the 90-93 accord is on the back left-hand side of the engine where the hose connects from the radiator to the engine, disconnect the hose and clamp it off or move it to the side as not to leak antifreeze (use a rag or container for antifreeze that comes from engine block). Unscrew the 2 screws from the hose adapter and take it off alone with the old thermostat. Replace thermostat as…
We Have a 88 Honda accord lx that keeps overheating have changed thermostats and checked timing belt replaced radiator and checked cooling fans still overheats?
If you replaced some of theses already ignore and go down the line # Not enough coolant # Water pump drivebelt defective or out of adjustment # Radiator core blocked or grille restricted # Thermostat faulty # Electric cooling fans blades broken or cracked # Radiator cap not maintaining proper pressure # Ignition timing incorrect
You replaced a bad heater hose in your 1990 Honda accord station wagon Then your radiator blew and you replaced that and the thermostat It still ran hot is it the water pump?
First, make sure it's completely full of coolant. Fill the radiator, start the car and and warm it up with the radiator cap left off. When it's warm, check the coolant level again to see if it needs more. Sometimes air gets trapped in the engine and you have to run the car to get it out. However, if that all checks out OK I'd suspect the thermostat got put in upside down accidently. It's…
In most cases, the thermostat will be in a housing that can be located by following the upper radiator hose back to its connection point on the engine. The thermostat's job is to regulate coolant flow through the radiator, and this can easily be accomplished by placing the stat in line at the water outlet to the radiator. The lower radiator hose usually goes to the low-pressure (inlet) side of the water pump. Answer the…
Follow the lower radiator hose from where it attaches to the radiator, all the way up to where it attaches to the engine block. You may have to move the air intake hose out of the way. Pull off the radiator hose and unbolt the two 10mm bolts. Thermostat will be in the block. Pull it out and clean the surfaces. Use a new gasket and make sure the spring portion of the thermostat is…
