I have a 2008 LNF with the weirdest coolant leak and i dont know where its coming from. I topped off the coolant about a week ago, i started the car last night and it read "low coolant". So it's a slow leak but i don't know where its actually leaking. The oil isn't milky, the exhaust isn't spitting out white smoke and there is no puddle or anything under the car. Has anybody else had this problem?

 

RIP block.

 

he said oil isn't milky

 

Sometimes it doesn't get milky for a while. Since it's a 2008, it's less likely to be porous block, but still possible.

The coolant has to be going somewhere. You can try cracking open your oil drain plug and collecting some of what comes out. If the water in the coolant hasn't evaporated, it'll be sitting on the bottom (oil and water don't mix, and oil floats). If there's nothing obvious, you can send that sample to Blackstone for analysis. They'll tell you definitively if coolant is in your oil.

This is what mine looked like when I did that:

 

I took it to the dealer, they pressure tested it and searched for a leak. Told me that it's probably my sensor, which makes sense because it wasn't really low. I'll still keep and eye on it and do what you said tho, thanks a lot.

 

I thought you said you topped it off? So it was actually low, was it not low again the second time?

 

Yeah it was down like half a inch below the line, so i poured a bit of water in there.
