This is for the 1995 k1500 in my sig. I have noticed that occasionally after I shut the truck off after warming up, I hear bubbling coming from the coolant res. sure enough, I see air bubbles surfacing in the reservoir. It does not do it every time. I have always had a very very slow coolant loss but not enough that I concern over it. (Maybe 8-16oz every few months). It does not overheat. The rad. Does not appear low either. I am planning on driving this about 750 mi this weekend and if it's serious I will take my 99 obs Yukon. Thanks in advance!
