Coolant low warning on - again...
A couple of days ago the coolant low warning came on again. Last time was around Christmas and the problem quickly became clear: the Jeep had a pretty good leak from the radiator.
One new radiator and 8,000 miles or so later, the warning is back and indeed, the expansion tank is right at the low level. I am not seeing any obvious leaks at the hoses, radiator, or water pump. I am not seeing white smoke or anything unusual with the oil.
Since I am not seeing any visible sign of where the coolant went, I am puzzled and concerned it may be the very start of a head gasket leak. I am taking the car to my mechanic tomorrow for a leak test, but in the mean time any thoughts from this group would be appreciated. I hope it's not anything major and that it can be fixed fast cuz this thing has to get me from Reno to the Bay Area on Sunday.
