On most GM V6/V8 engines the oil sending unit is on top of the engine near the firewall possibly under/behind the distributor. Look at the extreme rear of the intake manifold. On some others it is mounted near the oil filter. If you have a light it will just be a single wire. If you have a true gauge it may have a very small hose/line connected to it.

I have a 2005 trailblazer. The oil pressure gauge is ffine running around 40-50. When I come to a stop it drops to zero (under 1000rpms) I change the oil last night and it stilldoes this

The correct way of checking this is to put a mechanical test gauge on the engine and check the actual oil pressure. (your gauge is electro mechanical and it could have a "dead spot" in it.) However, if you don't have a test gauge, buying one or having a shop test it will cost you far more than the actual sending unit would. Therefore, providing that the engine isn't knocking or tapping while the gauge reads "0" ( which would indicate that the pressure was indeed low) I'd suggest that you replace the sending unit and see if it corrects the problem. The unit generally costs around $25.

If it has a constant reading you might have a bad oil pressure sending unit.Im not really sure where yours is located because there are different locations for different vehicles.Your local auto parts store can give you the exact location for your vehicle.

Oil pressure at 0 on 2005 trailblazer

It sure sounds like the oil sending unit is at fault,now sometimes,not always,the oil sending unit will seep oil or leak oil if they go bad,but like I said,not always,change the unit,and the oil and filter just for precaution.

I have a 2005 trailblazer. I got my oil changed

Could be either a gauge gone bad, or the sending unit. Unplug the oil sending unit with key on to see what the gauge does.

Have a 2005 TrailBlazer, Almost everytime I drive it for 30 -45 min the Oil gauge start to slowly drops to zero. If I turn it off for awhile its back up to 42ish then it slowly goes down again, I check the...

get under the car and see if it seems wet or if anywhere is leaking, and does the car act any differently? If you let it drop to 0 is it running fine? If the car doesn't seem to have an issue then it's most likely you need a new sending unit for your oil pressure

too much oil
