leaking oil cooler lines- upper and lower
 

i have replaced both sets of oil cooler lines , due to oil leaking from the metal swagges. now i see the lines leaking again. is there a fix; different after market lines; or try to seal with epoxy.

Bring the current lines into a hydraulic shop and have them fix them. Absolutely the best fix out there.

^^^^^^

Take your old leaky one to the hyd shop. The guys cut the ends off mine and attached a better hose in the center. They cant make those fittings though (the strange flare nut ones), which is why they have to reuse the lines instead of make you a new unit. Cost is cheap, they did mine for nothing cause our employers deal with each other.

I cut mine out and used some hydraulic hose from a local shop. I used Oetiker clamps on the hoses. I've mostly seen them used in underground sprinkler applications. Mainly because they are extremely cheap and can be compressed with a side-cutter(if careful), end-nipper(if careful), or the 'special' pliars. I've had mine done for almost 2 months now and temps have been anywhere from -10* to 70* today. So far they are still dry and driven on a daily basis. Total cost for both assemblies ran about $20 and that included making one set 2" longer so I don't have to relocate the filter mount when I do a body lift.

Not sure if there is room on a stock blazer or not but i screwed the oil filter right to the block and got rid of the lines all together. My front diff is lowered though for my lift so you might not have room. Something to look at though.

you all for the information. no hydraulic shop in my neck of the woods. I tried to get replacements for free from the parts store, but no luck. no lifetime warrenty. One hose is $40.00 and the other one is $36.99. I will check on line for a hydraulic shop and go from there.

I'd be willing to bet if you found a heavy equipment shop they would have something. The guy at the store I went to said it's not so much the oil or chemicals you have to worry about but the temperature. I'd be inclined to say that the OE hoses get hard and contract which results in a leak.

Do you have a pic or can you take one of the fitting they used?

I put all the info you need in this thread to remove the remote filter all together
