Hi Everyone,

I recently had the thermostat replaced on my X5 and the dealer somehow knocked the oil cooler so separated from the radiator while I was parked. I came out to a bunch of what turned out to be coolant leaking and after driving for a bit the car started to overheat. The issue has since been fixed, but I am still paranoid about any sort of leak from my X.

I was wondering, what does coolant look like when it looks? Does it have any sort of smell? I do have what seems to be water leaking on occasion when I park (dealer says it is condensation from the air conditioning) but I just wanted to know what coolant looks/smells like so I can tell if a leak ends up being coolant related.

Thanks so much!
