2008 Chevrolet Silverado - Answered Questions & Fixed issues

ooops a daisy that is a tuffy, mine had a special tool get get to the part that allows it to drop go to chev, dealer buyone n parts department.

The braking system and the engine oil lubricant, and coolant system are not connected apart from the vacuum hose. With the engine warm (not hot), gently hose it down and leave it to dry. The smoke is more likely external. If any did get inside the intake manifold, it will soon burn off on a good run.

P0641 Sensor Ref Voltage A Circ/Open Sensor switch is bad. Hope this helps.

when last owner put leds in it sounds like they have messed arund with the wiring, i would suggest you check that.

could be electrical but most likely bulk head control or vent accuators If you need further help, reach me via phone at https://www.6ya.com/expert/james_9c1b039055413ffa

What size engine ? 4.3 , 4.8 , 5.3 , 6.0 , 6.2 , 7.0 L You have a code P0xxx ? If your vehicle has Camshaft Actuator System it doesn't have a EGR valve !

Remove the pop in bezel. Look at the front of the stereo and see if it has two small holes on each side. If so you will need a stereo release tool to slide it out for the mount bracket.

Should be in the power distribution center under the hood.

In the exhaust pipes between the engine and muffler.

Why? DIY ? you need a repair manual, your auto parts store may have one, your library many, filepeep.com may have, or try manualslib.com You will need it again if youi want to DIY. Any way, follow the Exhaust piping back to the area usually under the passenger seat, and or driver's seat if there is a dual exhaust. It is in front of the Ehaust muffler. It will have an oxygen sensor in the front with a sensor wire going to the firewall and then to the ECU (brain). Thre may also be the same arrangement on the end of the converter.

left front of transmission at shift shaft.

I had the same issue. Check fuse number nine.

Check the link. Should be okay. https://www.google.com/search?q=Chevy+Silverado+4L60E+transmission+years+used ..

first buy a DMM meter ,spend $15 and end working blind. the battery and alternator are easy to test and for sure loss of any kind of DC power easy to find using the meter (ASK HOW) K2500 pickup or Suburban???? no told and wiring not the same. no engine told and that too sets wiring. OMG 6 engines 2 diesel. elaborate NO POWER< means head lamps dead? what? and stayed on? means what.? STEP #1 alternator work , battery NEG LUG OFF FIRST or you will blow the 100amp main fuse. doing this ALL WRONG and if a fuseable link, can be hard to find, as others say, not me. never ever connect any main battery backwards or you will blow up very expensive electronics, best I can tell is first failure was the fuse even those kinda hidden fuses called Fuseable links. fuses are first on cars, of head lamps dead and park lamps dead this is first, head lamps work keyon , or off. so is first thing to check with DC POwer loss, (NO POWER"?) if battery is 12vdc then the power is not lost but fuses are blown for sure. head lamps are a safety devices that work even no key in hand. the under hood box has a fuse marked Lighting, if blow HL are dead just below Lighting fuse is battery bus bar fuse. <<< blown? the only hard thing THIS CAR,is the online books stink back in 1992 no digital books then so most cars nobody was willing th scan 500page service manuals. (nor me) so only sparse information exists. (join k2500 real forums? Chevy)\ this truck does have (did new) 4 x fuseable links, 1 for alternator but only that blown kills alternator and runnining engine battery is not 13. to 15vdc so the battery goes dead fast 1/2hour fast. below 13vdc the alternator is dead or fuse link ALT is blown there are more LINKs to blow 3 more. others kill the cab or engine bay fuse boxes dead so all boxes must be check for lost of 12vdc raw DC power. head lamps parking lamps. to top the list and more, check all things DC power, even radiol the list of things dead tells you what fuse box is dead. hope that helps in any way. regards.

from the maker, ask them only and even ask for upgrades. and they are dangerous devices. even ******* in some states. never use one parked inside a garage. CO the silent killler, etc. the good ones (and oxymoron) have lots of inputs now that make it go dead. even door locks and more, OEM RS , blocks for huge list of things even any DTC errors from any computer in the car takes it off line, <<<<< see what OEM did very telling that.

but no control or lights. I huh?

o2 sensors bad, -5 is par, -25 means super rich and removing this much fuel. are you sure 55psi is right for all states>? keyon 3 times pressue cranking pressure if engine dead. idle PSI pressure will be lowest due to huge plenum vacuum below TV. and gunning engine hard will make PSI RISE to a;most key on PSI the FPR had 4 tests not just 1. exhaust leaks near B1s1 B2S1 will make huge rich running engine,.
