Oil Pump Change 2021 Silverado 1500 3.0 Duramax

Ian De Schryver — Wed, 29 Apr 2026 12:39:15 GMT

Hello,

It�s getting close to time to have the oil pump belt on my 2021 Silverado 3.0 duramax. I wanted to know what everyone recommends to change while everything is removed to get to the belt. So far what I�m thinking is:

-Oil Pump Belt
-Rear Main seal
-Transmission fluid, gasket, and filter change(since transmission needs to be removed anyway)
-Oil Pan gasket(oil and filter change)

Is there anything else recommended that I should have done(or removed from my list) while the mechanic is down there? I want to do as much preventative care as possible while the big parts are already removed.
Thanks in advance!

Hello there. I�m not sure if I�m just losing my mind or not. But I seem to be battling some fuel pressure issues with my truck. I have replaced everything pretty much except the hpfp. I seem to only get 33.06 psi desired at idle.ant About 600 rpm. and from the sensor. Not sure if there�s a difference between the rail pressure. Or if I�m just reading the pressure the wrong way. But it�s driving me nuts lm just wondering if this is normal or not for these newer units.

Can anyone assit with the ECM pinout for the EVAP Vent Solenoid control wire? I'm fighting a P0498 code and have replacee the solenoid and electrical connector and now suspect a wiring issue between the solenoid and the ECM. I located the ECM behind the wheel skirt at the drivers side front wheel. there are 3 large X-connectors, 2 black and the bottom one is blue. Need to idnetify the correct X-connector and pin number for the wire to the solenoid (negative pull-down wire). thanks!
