I have a 1999 Tahoe OBS with 105K miles and have been having an issue of coolant leak but random....Some times it is very light and some days a lot......and a few days of nothing. The temp runs below normal on the gauge and I had the head gasket done 4 years ago. I am going to take the shroud off tomorrow to see if I figure out where the leak is coming from specifically. It seems the leak is coming down the front driver side front it is "falling" off the front driver side bumper. Once I take the shroud off to get a better view...what can I look for to figureout the problem? Any help would be appreciated. Thanks in advance.
