Question about 2004 Chevrolet TrailBlazer
What does this mean and Coolant Thermostat
2004 Chevy Trailblazer
Along with all my mph and rpm is all going crazy what does this all mean
P0410 secondary air injection system malfunction. I've dealt with this problem myself. It's either the air pump which is located under the driver's side door on the frame, or it's the valve on the engine that is sticking.
The air pumps are notorious for "freezing up" in cold climates due to water sitting in the pump and freezing and then breaking the impeller from the shaft in the pump. This is what happened with mine.
Remove your pump and test it. If it spins and blows air,then it's fine. Then check your valve on the engine. If that opens (which they like to get corroded with exhaust gasses and stick) Then that will be ok. If not, you'll have a pretty good idea what is going on.
I wnt ahead and replaced both the pump and valve, which were both crappy.
GM also has a check valve that you can install to prevent water from entering the pump. I just drilled a small hole in the bottom of mine to "drain" the water.
