My 200tdi has recently started making a gurgling noise like air bubbles are coming up into the coolant expansion tank. The truck doesn’t seem to be overheating or losing any coolant, however it seems like there is some pressure buildup of the air/gas after about 30min of driving (I haven’t ventured beyond that to make sure nothing blows up on me). I have not recently made any changes to the system.
After reading many of the other posts this leads me to believe exhaust could be leaking into the coolant system via failed head gasket? Or could air be entering elsewhere?
Any other thoughts before I tackle the gasket?
it seems that many choose to install a completely new head instead of resurfacing the existing in the event that there are any small cracks. Is there a good source for these anymore or are they becoming NLA?
Thanks everyone!
