I have a 08z that im tracking the coolant on. The coolant seems to be dissapearing but i have no leaks of any kind anywhere. Nothings wet or greasy, and theres no puddles under the car even after driving. However the coolant level keeps dropping. Its a slow drop it was at the max line about a month and a halve ago and now its at the min line. The car drives fine. Sometimes upon wot above 5k rpm it has a weird sound but doesnt jerk or act like it loses any power, it pulls great. I think it just has to do with the excedy pro kit clutch kit i put in since the last owner had fried the clutch. Almost immediately upon start up theres white smoke and it clears after about 30 seconds and then comes back after 5min. The smoke is not heavy upon start up but is definitely much lighter after its had some time to warm up. It is also cold out so that could be effecting it.

 

Why not get a used oil analysis and see if there's traces of antifreeze in your oil? The UOA could also give you some insight into the condition of your engine.

 

where should i go to get the test done? Any known companies you trust?

 

Try blackstone- lots of people here have used their mail-in UOAs.
