Where is the oil drain plug on my 2006 two wheel drive ex cab chevy colorado. I can not find it anywhere please help me!!

I think you have a lot of room, look at what has to be removed, drain coolant, disconnect the hose remove fans, transmission lines they have o rings for leaking oil, use adjustable players to remove clamps, fill up coolant and let the air off by bleeder.

plugs are always the last to suspect when there are misfires
It is most likely injector problem from
low fuel pressure ,
dirty injector tips , injector wiring and harness or
ECM problems

You don't have any. factory puts in sealed tie rods, ball joints. I know it's a rip, but it keeps there parts department busy

if you change your oil every year/10k then 10/40 semi is fine.

This is for the 5 cylinder 3.5 liter engine in the Colorado

1. The drain plug is in the middle of the oil pan on the drivers side.
Use a 15 mm socket or box end wrench to remove the plug. Drain
oil.
2. The oil filter is at the bottom front corner of the engine on the passenger side. Remove the filter. Try not to tip the filter when you
remove it so you don't get oil on other parts of the truck.
3. Rub a small of oil on the gasket of the new filter. Spin on the new filter, 3/4 to 1 turn past when the gasket starts to seat. Hand tighten
only.
4. Reinstall the drain plug. DO NOT OVER TIGHTEN OR YOU COULD
STRIP THE THREADS.
5. Add 6 quarts of oil to the oil filler tube located on top of the engine
in the front and middle of the engine compartment. It shows the location
in the owners manual. Install the filler cap.
6. Start the engine and let it run a few minutes to fill the filter with oil.
Turn off the engine and wait a few minutes for the oil to drain down to
the bottom of the engine. Remove the dip stick and check oil level.
Checking oil level is in the owners manual.

hi its situsted next to front passanger wheel in line with the transaxle you will see the oil pan the drain plug is on the back please rate this answer

It is on the side of the pan on the driver side.

It is due to the cold weather,The fluid is to thick when cold for the actuator to engage the 4wd.
