Just wondering if anyone had similar symtoms for this sort of coolant leak.

2 months ago, I got into an accident (their fault, their insurance covered repair work). Damage was at the front passenger side corner, impact was on my HID headlight. Speed was approx 35-40. Everything was fine before the accident...

About 2 weeks after getting my car back, I noticed a puddle in my driveway. I took it into the dealership since it was due for it's annual maintenence anyway. SA said they found a coolant leak. So they supposedly fixed it. 1 week later, I noticed the fluid line was below the Min. line. So I took it back to the dealership. They ran tests and can't find the problem. However, they replaced the thermostat anyways since I'm still covered under warranty. A week later, I checked my coolant level to find the line below Min. again, however there are no puddles on the ground.

Where else can I check for a source of problems if there's no puddles to be found, yet my coolant level keeps dropping, and the dealership techs can't find any problems??

 

im in az and that happens to me all the time and my dealer tells me there is nothing wrong i dont believe it though. there has to be something wrong my mini isnt just thristy all the time is it?

 

I have been experiencing the same leak since about 40,000 miles. Overflow is empty every several days (depending on drive distance). Any suggestions??

 

Mine was dropping due to bad cap on radiator never noticed steam or anything they had to do a pressure test

 

Had a similar problem after being hit on the driver side. Finally replaced the radiator and no more problems.

 

Had this problem over the summer. Turned out the header cap (coolant tank) was bad. Replaced, no problems since.

I have the exact same problem, but so far no solution. Took it into the dealer the first time and they replaced the thermostat. Second time they said the gasket that seals it closed had been bumped a little loose when they put in the new transmission, replaced the gasket. But I still have to fill the coolant every few days.

Does anyone know specifically what the problem is? Or could this just be one of half of a dozen minor annoyances?

Thanks!

 

check the rad cap. a lot of times people think its tight and its not causing a slow leak. the dealer replaced my heater core and after leaving smoke started pouring out of the hood...popped the hood and saw the coolant tank was wet so i took the cap off to check the seal and re-installed the cap and it was fine.
