    1988 K3500 454 engine oil cooler lines

    I looked on rock auto and it is not clear on the selection. Even Dorman isn’t clear on what to get. Are they under normal engine pressure.?

    1988 454 belt

    I just wanted to follow up that the belt for a 91’without air pump works. The only downside is I ordered it from Amazon (Gates) and it was probably 20 years old and made in the USA. Hopefully it will last. The ad on Amazon says made in Chin, but the vendor probably bought up old stock.

    1988 454 belt

    Because I had to ruin the air injector lines when I took the old ones off. The new ones came with plugs that I used. Why have a pump and a bunch of plumbing under the hood doing nothing, that’s why! And the belt choices are for air conditioning or no air.

    doors rattle when hitting bumps in road.

    I did something a little less ghett. I put a self tapping screw through the door post to hold the striker nut in place, took the striker pin out and put a piece of vinyl tubing over it and put it back together. No more rattling over bumps.
