Question about 1996 Buick LeSabre

1996 Buick LeSabre coolant sucked into engine

The second time this has happened in less than five years! The first time it happened I believe they replaced the plenum and spark plugs. Is this going to be a reoccuring problem with this engine?

Sounds like a leaking intake manifold gasket to me. VERY common with these engines. Are you having to add coolant quite frequently?

1996 lesabre no start but fuel pump makes noise

replace the radiator cap and keep the reservoir bottle up to the line . Check that the hose from the radiator is in good condition. What you have is the hot coolant escaping to the reservoir and as the engine cools down the coolant is being sucked back to keep the radiator full . but sometimes the suck back is not happening and that points to the cap

1986 buick lesabre 3.0 L engine coolant sensor .

Its just a relay or the computer or sensor, check a manual at an auto parts store, they can look it up. but to fix it quick, just run a new power and ground direct to the fan, so it runs when you turn the engine on, I drove My 90'Olds cutlass like that for years.

I believe your head gasket is shot. Check your coolant level, it's probably going down. What's happening is your coolant is leaking into the oil where the gasket has failed (there are channels in the head of the engine that oil travels thru to lubricate the engine, and other channels (passages) that the coolant flows thru to keep the engine from overheating. This needs to be fixed with the installation of a new head gasket. countrycurt0
