Thermostat on 2004 Honda Accord not opening, No Heat

The heat in my 2004, 4 cylinder, Honda Accord quit working, we replaced the thermostat ourselves. It worked 2 days and quit again, we drove a few more days and it kept leaking coolant somewhere, but didn't leave any puddles and periodically it overheated until we put more coolant in it and then heat would work again for a day or so. Took it into a shop this time and they said the new thermostat was not opening, so they replaced it again. Now 2 days later, again no heat. Anyone got any ideas?

    We'll check it out, but no we haven't really smelled any coolant. The guy at the shop had mentioned that when he first looked at it but then decided it was the new thermostat. Thanks

How to replace a thermostat on a 1996 honda accord dx?


It has been some time since I looked at a Honda, but it is usually quite easy to identify the thermostat housing. It is a dome shaped fitting where the top radiator hose is connected to the cylinder head.

This fitting is bolted down with either two or more likely three bolts.

Undo the three bolts, then carefully separate the thermo housing from the cylinder head using quite a bit of force.

Carefully, because it is made of cast aluminium, but it is also stuck down with gasket sealer and lots of heat from the engine - it normally takes a hard smack on the flange or a flat object such as a screwdriver wedged between the flange and the head to loosen it.

Once open you will find the thermostat inside. Replace it with a new one and don\'t forget the rubber "O" ring, and if it was sealed with silicon sealer, clean all surfaces and add fresh sealant.



Good luck.

Heater and defroster don't work well


Connie this sounds like your thermostat in the engine is stuck open not letting the water stay in the engine block to heat up. The fix is to replace the thermostat with a new one that will allow the water to stay in the block to warm up. The typical symptoms of a stuck open thermostat is that the air will blow somewhat warm but never hot in the winter time, but it will take a few miles for the air to warm up at all. I would check with the dealership and find out what degree thermostat to replace it with. I run a 180 degree in the summer and a 195 degree thermostat in the winter just to have hot heat in the winter. I hope this helps

My 1992 accord does not blow.heat when outside temp drops below 40 degree.


If you have heat when its above 40 degrees most likely your problem is a bad thermostat, when it gets VERY cold out the engine cannot reach proper operating temperature to maintain heat quality because the thermostat is more then likely stuck in the open or partially **** in the open position....

1994 Honda Accord heat/cool system


There could be an obstruction in the heater core under the dashboard. It's also possible your thermostat is stuck in the open position. I'd start with changing the thermostat. As far as your A/C goes, either you have a slow refrigerant leak and whomever did the servicing didn't bother to check for leaks and/or the A/C compressor could be malfunctioning. Unfortunately A/C problems can be costly.

Car doesn't warm up


It does sound like the thermostat. The sensor does not control the thermostat in any way, it only reads the temperature of the coolant. Your symptoms are classic of a thermostat that is stuck open or partially open. Take it back and tell them what is going on and have them show you that the thermostat is fine.
