While looking into my my suburban is leaking oil, (which appears to be the oil cooler lines) I noticed that the brace on the driver side doesnt have a bolt in it on one side. Therefore it move when everything vibrates. It moves and hits the oil cooler line. Well now I figured out why it started to leak however I need to know what size of bolt goes into the brace. Also whats the easiest and cheapest way to fix the line? I read on here about new lines cost upwards of $300. However when i looked at autozones website it says its around $20 per line. Am I looking at the right line? Will this line work and go from the cooler all the way to the oil filter adapter? http://www.autozone.com/autozone/parts/Dorman-Engine-Oil-Cooler-Hose/1995-Chevrolet-K1500-1-2ton-Sub-4WD/_/N-j1yodZ93yeo?counter=1&filterByKeyWord=oil+cooler&fromString=search&itemIdentifier=434442_118221_0_ Do I need anything else to change the line? Im assuming that I must drain out the oil first to replace the line. So, a summary..... Question 1- What size of bolt do I need and where can I get it from? Question 2- Is the the correct line to go from cooler to adapter? Question 3- Do I need anything else to change it? Question 4- Do I need to drain the oil first?
