Where is my coolant going?

**AWD87** · 12-02-2008 02:28 PM

My coolant warning light went off about 3 months ago so I added some coolant. Now, the light is back and sure enough I had to add some more coolant. I have no idea where it is dissapearing however. I can't see any leaks or anything. Anyone know what the issue might be?

These motors like to drink coolant, Just keep adding it when the light goes off

Check EVERYWHERE for a leak.

my first leak was the aux water pump.... then a warped head so far. JHM hooked it up and fixed it well.

My Last Coolant Leak Came From the coolant Sensor on the Passenger Side of the motor where the Rubber O-Ring was Rotted out. and was leaking from that sensor since there was no o-ring. might wanna check that out.

I have a coolant leak that is showing a little liquid on my engine cover right next to the coolant tank, but I can't see a leak anywhere around the tank. Inspected multiple times so I feel your pain.

Your coolant tank could have a crack.

check the drivers side valve cover for any dried white residue. Your expansion tank could be leaking or one of the hoses that goes into it.

in the next week or two im replacing my aux. water pump which is under the intake mani... if you take off the front engine cover take a flash light and look down under the intake mani and if you see some crusted up pink goodness, that is your leak. I have a VERY minor leak, that I'm only fixing because I'm having a bunch of oil seals fixed up.
