anyone have to refill their coolant reservoir every week or couple of weeks? is this a problem? could it be from the 90+ degree temperature the pass month?

 

your coolant doesn't evaporate when it gets hot, it should be a sealed system in there. You probably have a leak somewhere.

 

look below your car after leaving it parked there got about 15 mins and if there is any liquid under your car check it out and see what color it is and smell it. if it green and has a funky smell then you are leaking coolant and need to get some radiator stop leak or something.

 

Mine too. need to add coolant twice a week! But didn't see any coolant leaks under car or around upper horse. Just changed timing-belt and water pump a few weeks ago. Any help?

BTW, mine is 91 integra LS. Thanks !!!

Integra's are known for weak radiators. The end tanks are made of plastic and crack over time, so that's probably your problem. Either that or one of your hoses is cracked. I have the same problem I just found out last week. In the engine bay, do you see any water spots anywhere?

 

GOt some water spot under passanger side ground. Will have the radiator and horses replaced this weekend. Thanks.

 

Yes, found cracks near the top plastic part. Got a new csf metal radiator and horses installed. It runs great now BTW, total cost me around 310 parts and labors. Is it too much for the job?

 

metal ones are cool. i dont know the brand, but $310 sounds like a good deal. i think my friend paid more for a OEM replacment.

 

Here is one more credit to the new radiator. Before installed the fan awlays turns on after a highway drive but now the fan is quite. Also, engin is running at lower temperature.

 

that's very cheap for an all metal radiator. i paid $140 for an OEM replacement (didnt care about going all metal because i'm not keeping the car forever).
