How do you replace the oil lines on a 1988 Chevy S10 4.3 V6 4x4?

Answer 1

Assuming its like a 94 bravada 4.3l 4X4, This is what I did: 1. remove air filter. 2. disconnect oil lines from filter housing (1) 13mm bolt. 3. remove clamp holding oil lines, its about 8" down from the filter housing. 4. jack up front of truck and secure. 5. remove front driver wheel, 6. remove big black plastic splash guard under radiator,(6)15mm bolts. 7. jack up motor some without loosening motor mount (this helps provide clearance) 8. remove bracket that extends from block down to bottom of transmission, the one between the two oil lines. note: top bolt can be reached with a short 15mm socket/u-joint/long extension combination through opening along right side of upper a-frame. 9. get two long extensions with a 3/8" drive handle and 13mm socket to reach in from front of truck to (1) 13mm bolt that attaches oil lines to block adapter, from wheel well you can guide the socket onto bolt head. 10. pull lines out from below. 11. if you want to replace the gaskets between the adapter and block remove (2) 13mm bolts from under truck and fish it out from wheel well. I heard these gaskets cost $4 from the dealer. It's a messy job especially if your lines have been leaking a long time. This may not be the "right way" but it worked for me. The lines cost about $50 on ebay.
