Hi,
I Have A 1994 Gc 3.8 And Was Wondering If Anyone Knows How To Change The Spark Plugs And Wires Without Pulling The Engine ? Also Do You Need To Change The Timing Chain At 120,000 ? This Car Runs Fine At The Moment, What Other Things Need To Be Adressed At That Milage ? (engine Wise) I Am Taking It To Another Country As The Car Is In Showroom Contion ,just Looking For Things That Can Be Fixed Easier Here Before I Take It. I Am Doing Brakes ,sensors, Wires, Plugs.
Alternator Is 1 Year Old Raditor Is 3 Months Old.

Thanks In Advance.

Jim

As you well found out the front 3 plugs are a breeze, the back 3 takes time and helps you develope new words. I change mine from the top and with a combonation of the correct length extentions I manage to get it right. The timing chain should be fine, I changed mine at 120K and it wasn't ready to be done. You must however change the serpentine belt. If you have not checked the emmissions yet, it may be time for the oxygen sensor to start playing up. Take with a spare oxygen sensor and a timing chain set and a serpentine belt tentioner.. ... regards
