Hello people back with another question for you smart guys.

About A month ago I put in new oil cooler lines. The ones from the radiater to the oil filter. However I did not replace the fittings, but I did replace the blue clips. Now today my car overheated, turned it off and inspected and I noticed I had very little oil. I looked under the car and noticed I had a bad leak comming from somewhere. I put a new bottle of 5w-30 in and drove it home. Once I got home cranked it back up and noticed the leak was comming from the bottom oil cooler line, 1 drip every 10 seconds or so, pretty bad. It was leaking from the clip, not where the fitting actually screws into the radiater. So I'm assuming the o ring inside was bad, can't think of any other possible causes for it to leak. Ordered a new fitting from advanced will put it in tomorrow. Just wanted to check with you guys and see if there is anything else I should check or do besides putting in new oil and changing the fitting/connecter whatever you want to call. I'm always paranoid about doing repairs after an overheat, don't want to cause anymore harm to the engine then what could have already possibly been done.

Thanks guys.

 

Some people say that you can reuse those fittings but I have never had such luck. IMO they should be replaced every time those lines are disconnected. I have the Dorman part numbers somewhere.

 

Those stinking oil lines are the source of so many problems! GM's replacements will be leaking within 6 months and naturally - no warranty. Dorman has lifetime replacement warranty but even those are leaking (after pulling the GM's... that leaked after the GM's...)

Some folks pull them & replace them with hoses fabricated at a local heavy equipment hydraulic hose shop. Not super expensive and you'll only do it once. You have to get some union fittings etc but if you take both ends (filter mount & threaded radiator insert) you can get threaded ends too that replace the leaky GM 'clip & slip (off)' fittings.
