Having problems with your 1994 Buick Park Avenue ?

Leaking anti freeze from under the air intake hose under tps sensor right where the plenum and upper intake meet it appears

Answers :

The plastic intake upper plenum is known to warp,causing this leak.I believe too much heat from the nearby EGR port.the solution is more than just a new gasket, an upper intake is usually required.there are aftermarket suppliers,which could save you some money on parts.be sure to check around...good luck
