1990 Acura Integra


1990 Acura Integra

In my 1990 integra my car was running hot a few weekes ago so I removed the thermostat. I'm not sure if it was bad or not but I let the car run without a thermostat for about 3 weeks. Ever since the thermostat was out the car started leaking coolant. Sometimes so bad that the radiator would be completely dry after 20 miles and the car would come close to overheating so I would turn it off. Sometimes it wouldn't leak at all. I put a bottle of stop leak in and it worked for about 4 days then started leaking again. I put a new thermostat in last night and the car still leakes. Im not positive where the leak is coming from but it looks like it might be near the engine or from the engine. The puddle is on the passenger side close to the tire. It looks like it's coming from near the lower radiator hose where it's connected to the thermostat but both the hose and the housing are dry so it can't be either of those. The leak streams down right below where the upper hose connects to the engine and hits the ground from there. Any ideas where the leak is coming from or what I can do to fix it? Thanks

Do you
have the same problem?

Hi biggs_charlie,

I am confused. You were able to see the leak coming from the upper hose and yet you are asking from where.

We would not be able to see the leak so you have to find the source, it could be the hose or the joint.

Top up the coolant and close radiator cap. Press the upper hose with your fingers to create some pressure in the system and see where the leaking is coming from. Use a mirror if necessary.
