How to replace an oil pump on 5 cylinder 3.5L 2005 Chevy Colorado 4x4
Posted by Anonymous on
A bad oil pump will show low oil pressure and your lifters will start chattering. It is rare that ann oil pump failsyet possible.The oil pump is in the oil pan and will require the pan to come down. The pan can be remove in frame, you just have to turn the crank by hand to get the crank journal out of the way at a certain point. Yhe oil pump is the unit the pick up tube and screen are attached and it comes down by removing two bolts.The pick up tube is the hard part. Last I kmew they are pressed in and hard to separate from the pump, but it can be done. Be careful not to rotate the tube or it will be loose on install, not good.. If you have a oropane torch heat up the pump, don't over heat. Just enough fotr the tube to dlip out. Do not forget to put the distributor drive rod back in if it came out wiyh the pump. Pull the distributor so you don't fight thre drive slot alignment. Note rotor position and dirtibutor body position. Mark if necessary the orientation for assembly. Good Luck. Suggestion. Have the oil pressure ck'd and verified befor siassemblin. Put a gauge in place of sending uni for a direct reading. It's a lot of work to pull the pump. Good Luck, -Ned-

I paid $18 at the dealer for just the knob. Then I found it online here for $4.70

Replacing the sending unit / module is optional when its a metal top module. If it's plastic I would replace the whole thing reguardless.
I hope this helps.
