I have a stainless after market grill on the front of my car. It always has a stain in the center. I removed it and saw that the stain was on both sides. I can smell anti freeze on rare occasions so I keep a eye on the coolant level in the radiator. It never has dripped any fluid on my garage floor. It has never been low altough the resevoir bottle does seem to loose some. The car is a MY2000 and it is almost time to change antifreeze. My plan is to have it pressure tested and see if it leaks. If any one has a idea please let me know.

If it were not for the grill I would have no idea that it leaked.

Thanks,
Elliott

 

If its leaking it has to go somewhere. Do you ever puff white smoke out your exhaust? Have you ever had to add coolant to the resivoir bottle? Can you see any build-up on the engine anywhere? I would get your coolant flushed and preasure-tested and just go from there if you don't have any of the above.
