I have a 2002 durmax diesel with a Low fuel rail pressure code and with surging at idle. How difficult is the sensor to replace?

Is it the sensor of air in the fuel rail. Have the fault codes read.
Replace the faulty units with genuine one because most aftermarket units are not set for OEM cpu units and are not completely compatible

Fuel in my oil 6.6 durmax

1.Check your fuel injectors, they may be over fuelling the combustion chambers they may need replacement.

2.Check your oxygen air flow sensor.

If problem persists, then you might consider an engine overhaul, since
your compression rings allow fuel to sip through to the oil sump.

Low Coolant Level remains on my 2002 Chevy Durmax 2500HD Diesel. Added coolant. There's no leaks. The light's still on. Why?

possible clean sensor on tank or replace. its probably just one of those things, if coolant level is visually good keep an eye on it as you drive a couple days. also watch temp gage for normal temp.

I have a 2002 chevey trailblazer,and the a/c only works on 5.why is that?It has settings one through five,and it only works on five full blast.

Your control switch is bad. This is a bad problem with chevys. Even earlier year models had the same problems. I wouldnt get one new, call your local salvage yard and get a used one. Please rate answer accordingly!! Thank you

Does the engine on a 2001 Chevy Silverado 3500 Durmax Diesel need to be cooled before changing the Thermostat? And is cold weather bad to do this in?

a hot coolant system will have preshure so that need to be relived, but is you dont mind burns it is ok to do hot, and ther is no problem doing this in cold weather.

Only hot air blows out vent when switch is in cold or blue area even when ac is on

Could also be that you are out of Freon, Compress may have a leak. Try it on cold setting in the early morning if its not even cool and heats up fast then Rob is correct. ITs a damper/ temp problem which is eternal. You can tear apart you dash and check on the damper (looks like a doggie door) make sure nothing is in the way and the hinger isnt broken.....I hope you can fix it yourself..
