View Full Version : Leaking coolent

My LIM gasket is gushing out coolent only externally. The coolent tank was 1/2 full. I drove the car for 2 miles and when I came back, the tank was nearly empty. Is it possible to have LIM leak this quickly or could it be something else?

You need to get that fixed now. Check under the oil add cap, is there a milky residue? If the oil looks at all milky, your getting coolant in the oil, and that'll cause lots of bad stuff to happen. The LIM causes far more 3400 engine failures than anything else you could think of. Don't let this problem go unchecked, don't drive it till you've got it fixed.

Checked both oil cap and dipstick. No signs of milky oil. Yes, I am aware of this.

check the water pump. is there any coolant there? or just under the pump theres a spot on the engine where it might pool. I just replaced a shot pump a few days ago. Did the work myself VERY easy
