My 2000 Buick Lesabra 3800 has a ticking noise coming from under the hood what could it be..not leaking oil or any fluids...checked oil and it's fine


If only when engine is running, probably valve tappet noise. How many miles on engine? How often do you change oil and filter?

If there are no coolant leaks then check your engine oil to be sure it is not over full or foamy because if there is coolant getting into the oil it will cause irreversible damage to the engine. If the engine has ever over heated the head gasket/s could also be leaking and will need replaced.

My temperature gauge fluxuates from cold to hot,but my heater blows cool air then hot air...I don't know what to do. Also my hose the leads from the radiator collapses then gains its shape then does it...


you have air in the cooling system, you need to remove the radiator cap then start engine and top radiator off with anti-freeze. then look the system over for leaks it may have a small leak that over time has allowed enough coolant to escape to cause this problem.

Buick review


Good engine 28 mpg+ hwy. These 3800 engines had upper intake problems and would leak coolant into the combustion chamber. The new ones were re-designed and do not give any trouble. My 90 buick 3800 has 295000 miles on it. If yours is supercharged it does not have that intake problem.

Not really. The head gasket is not mendable from outside with epoxy or inside with sealers. Good luck.

this is a common complaint, GM/Buick recommends you remove the sensor from the radiator side tank and replace it.

Im assuming this is the Series I 3800? If so, if you can email me I can send you some directions on the process. Its for a Series II 3800 but it should be similar. If you cant email me, post up and I'll see what I can do.
