I think I have a coolant leak from a pvc elbow piece on the left side of the engine and my car keeps overheating.


Do you have the 3200....or 3600 engine. Is it an elbow right above the water pump housing???? That would be a cooling/heating tube to the heater core. A "PCV" valve recycles, or sucks up unspent air in the crankcase & re-combusts it by re-routing, thru the carburetor, or throtte body. On most these I have worked on, there is a small brass "bleeder" valve in that vicinity on the engine. Hold the base of the bleed still (usually 10mm) & make sure the bleeder valve on top is tight, (usually 7mm). If those are OK, try that small hose, that makes that 90 degree bend there that is about 6 - 9 inches long. When they have ruptured on me, that is usually, preceded by a deteriortion, on the "rear" side where you cannot see it. Always seemed dumb to me, but, the back of the hose, is closest to the valve cover & THE HOT engine. Where else would it deteriorate??

Rubber type plug ( passenger side of radiator) on bottom is dripping; gauge on instrument panel will show hot temperture quickley; even after adding coolant; name the plug and how to replace


That is your radiator plug. You take it out to drain the radiator. You just take it out and put another one in. Is your radiator fans working? It may be the radiator itself. Plus, it may be a coolant temp sensor. If it is a small leak, with full coolant, it wouldn't overheat quickly. Make sure the fans kick on. Check radiator.

Have someone pressure test the cooling system - you likely have a head gasket leak

I have noticed a couple of drops of anti freeze on the floor the last couple of days the bottom of the car is starting to get wet with antifreeze


Right above the water pump there's a 90 degree elbow that's made out of plastic that comes out of the intake and goes to a heater core hose. That's where mine was leaking. Get it replaced soon because it will get worse. I heard this is common on these 3.8L engine.

I have a water leak coming from my engine block. How to repair 2001 Buick 3.8 It is come out of a 5/8 pipe or around it


If it's a hose, best bet is to just replace it, and use new clamps.

If it's leaking where it's connected to the nipple, for a quick fix, you can remove the hose, cut the hose off past the leak, and reattach it.

This requires a little bit of slack in the hose, but if the leak is right at the connection, there should be enough slack in the hose to do this.

Yeah on that vehicle there is a 90 degree plastic elbow that goes from the belt tensioner to the intake manifold and on both ends there are O-rings. Definitely need to repair this as soon as possible. Not sure your technical abilities but you would need to remove the serpentine belt and alternator and a bracket if I'm not mistaken. Usually takes me about 45 minutes to repair but I have been doing it for awhile. Good luck and Happy wrenching!!!
