I had an overheating issue with my 14”jeep, burped yesterday no more over heating issue runs perfect only issue is on start ups I blow white smoke everywhere until it warms up, no smoke while driving just on start up and sometimes idle any ideas, I know headgasket might be the case but I’m hoping for an easier and cheaper solution haha
Steam on start ups
- Thread starter megatronjku
- Start date
I’d suspect the head gasket. Have you checked the oil to see if it’s milky?
Sorry forgot to mention that, yes pulled the oil drain plug for an oil change looked perfectly fine
The oil doesn't always have to be milky for a blown/cracked head gasket, crack in the block or cracked head. Not to be confused with crackhead though.
White smoke on startup is the cardinal sign of a coolant leak. Check a sample of your coolant for combustion products. You can get an inexpensive test kit at your local auto parts store.

If you park your jeep on a hill or elevated surface that can also cause it on cold start. I have a 6.4 Hemi swap and my driveway is pretty steep. It did that to me couple of time. Freaked me out and I went all banana on the shop that did the swap. Long story short after parking it on flat surface cold started it and monitored it for a week and white smoke went away. This might not be the reason in your case. But for shit and giggles and to pin point the issue, It might help.
