Coolant leaking on 2005 BMW 525i
I recently notice that the coolant level on my 2005 BMW 525i is getting low, I have to add water or coolant 1 quart every one or 2 weeks. Driving seems OK, it sounds like there is a leak somewhere with coolant. Can some one give some clue how to check it is the coolant leaking or something wrong with water pump?
Thanks, |

Go to an auto parts store that rents out tools and borrow a pressure testing unit. It gets attached to the expansion tank. Pressurize the system and look for a leak. There is also a fluorescent dye you can add to the coolant and then use a black light to look for the leak.
