[QUOTE="james6873, post: 429378, member: 19771"] ***2008 wranlger*** I had a couple times where after driving for about 25 minutes, sitting at a traffic light it would seem to boil over- as in the reservoir was bubbling rapidly even after i turned the vehicle off. I got stationed in japan for a while and now im back to NY where i had my jeep shipped and im having this same problem once agin. The coolant bubbles after about 25 minutes of driving it, and continues bubbling in the reservoir until the engine cools a little. I've super flushed the entire system, replaced the thermostat& gasket, replaced the coolant, bled the air, inspected hoses for leaks and clamps as well. It's not a head gasket because i've been driving it for way too long without exploding, also no coolant in my oil and no steam out my exhaust/under the hood. Could it be a crack in my radiator or water pump/gasket creating air bubbles every time i drive it? side note- the other day i found i havent been using the right coolant (i thought coolant was universal) (ive been using peak 50/50). i heard this can cause corrosion/air leaks in your water pump. Also the jeep is a manual, idk if that makes a difference. [/QUOTE]
