Car knocks when I start it


If it has the 3800 engine, usually the issue with this engine is at some time, the upper intake manifold (plenum) developed an internal coolant leak, from the plastic housing just under the throttle body, from the EGR tube that flows in to upper plenum. This causes the coolant to seep into the lower intake manifold ports and into the engine cylinder, on top of the piston, and when the engine turns over, sometimes this coolant causes this concern. If at any time you started your engine, and it stopped turning (cranking) over for a split second and then cranked over to start, this could cause the connecting rod to bend slightly causing the internal engine knock. Was your coolant/antifreeze ever low?? Is your engine oil have a milky color?

Location of knock sensor and digital egr on 3800 engine because it failed nox test. need to replace


Hi,

Improve the Fixya.com experience for everyone by voting!

Your knock sensor on your 3.8 litre engine is under the hood, passenger side, rear engine area, below exhaust manifold, mounted in engine block.

[I'm not alloted enough space to show you a picture of the knock sensor]




Your EGR valve is located under the hood, center, driver side, mounted on upper center driver side of engine
[I'm not alloted enough space to show you a picture of the GR valve]
All the best,

I have a 2000 bonneville 3800 series 2 engine,when the engine warms up it has a tick or knock but its not in the engine it works good. Could it be the flywheel


The sound you are hearing is probably the fuel injectors firing...this is normal to a point but a louder tick may indicate your injectors are becoming clogged. Fill your tank to half and add a large bottle of fuel injector cleaner... the cheaper the better as you want to run this mixture to near empty. After that add half a tank without and I bet your noise decreases ,milage increases , as well as performance. Hope this helps you out ...a reply would be appreciated! Thanks for your question.

1999 Pontiac Bonneville 3800 engine. How do I replace the water thermostat?


Follow the top radiator hose down. It will connect to the engine. At the point that it connects to the engine is where the thermostat is located. This thermostat cover will have two bolts. Some of the 3800 engines have a temp sensor in the housing. You will not have to mess with the sensor. The housing will have 2 bolts that hold it on. Remove the two bolts and the housing will lift off. And the thermostat will be under the housing. Replace the thermostat. And reinstall the housing.
