Where are the spark plugs and wires located in my colorado

ATTEMPTING TO LOCATE THE TWO IAT WIRES IN THE MAF SENSOR PLUG TO INSTALL PREFORMANCE CHIP IN a 2012 COLORADO 3.7 engine.

Measure the resistance. But if you had bad plug wires you should get a Service Engine light with a misfire code.

You should see a spark plug wire for each spark plug. The spark plugs are in the cylinder head. You have to unplug the plug wire first before you replace the plugs. Be careful as to not damage the plug wires when removing them. Be carefull not to get dirt into the cylinder when replacing the plug. Do not overtighten the new plugs. I can't remember which side of the engine the plugs are on, on your truck. You truck has the inline 5 cylinder I think.

need new plug wires and spark plugs

under the individual ignition coils (the coils are over the spark plug) in the cylinder head.

under the plastic in the center of the engine 5cylinder must be cold or can warp head use aintseize on new plugs check gap hope this helps

Should black coil assembly going across top of engine,remove and plugs will be located underneath.

This is the 3.5L inline 5 cylinder engine. The spark plugs are at the top of the engine. They are covered by a hunk of plastic called the "Air Intake Resonator".  Remove the plastic. Carefully pull the ignition coils from the spark plugs. Unlike most other cars. The Colorado has a coil on every plug.  This boosts ignition power, but, every coil is expensive. Do not harm them.

they seem to be under the aircleaner and intake components. The coil is at the back near the fire wall. take off the air duct work and go from there. be careful to reconnect all sensor hoses , wire plugs exactly the same way you took them off. I think you will need several tools before you get to the plugs.

what is involved in changing spark plugs and which type is recommended?
