Oldsmobile/Buick Repair: 1998 Buick LeSabre coolant leak, coolant leak, buick lesabre
QuestionMy 98 LeSabre (3.8L) is leaking coolant where the metal heater hose enters the intake manifold. I see no clips or fasteners of any kind holding the heater line to the manifold. Is this line just pressed into the manifold and sealed with an o-ring?
AnswerHi
If it is a 98, and the elbow that is between the lower intake and the tensioner, they do have o rings, but the plastic more than likely is failed.
I would also recommend, if you end up replacing the one in the intake, to replace the one between the tensioner and the water pump outlet.
I hope this helps
