Put car in neutral, remove wheels, calipers and rotors, diff. cover. rotate carrier until you see wrist pin retaining bolt, remove bolt and slide out the wrist pin out of carrier. Next push axle inward to remove inner axle "C" retainer washer then slide axle out of tube. Then pry off axle seal and with slide hammer w/attachment remove axle bearing.
if your rubber hoses are cracked and leaking then replace the hoses with proper size and length.
if the hoses are leaking where they connect to the metal fittings from the heater core then try and tighten up the hose clamps -- they could just be loose.
Fuel pressure? Do you hear the fuel pump running? Read the codes to see if ECM is still alive. Do you have spark at the plugs? Remember all motors need 3 things to run air, fuel, and fire at the right time.
You kn ow you have to take the outside chrome piece off, right? If you have the top screws out, you can usually just bend it forward enough to get the headlight out.
hello I will take a picture of the Diagram and send it to yea I have a 86 Iroc z28 So i have a Haynes manual for yours as well for most of the f body's are universal. I need a Email or a way to send you the file?
when your heater core goes bad, generally it leaks inside the car and can leave a odor of antifreeze. It can effect colling of the engine...so I would change it.
It is behind the dash..but not a huge deal..take your time some saturday afternoon & youll have it
