Oil cooler lines leak?

[992door]

Did you put the o-rings on the hoses when you replaced them and are they seated good in the fitting?

 

[4myfreedom]

no o rings they did not come with

Just to make sure we are taking the same thing. You replaced the 2 hoses that run into the radiator?

 

[4myfreedom]

yes i did

OK I am pretty sure that there should have been o-rings to go on the connections. Sunlit would probably know for sure whether they should have them.

 

[4myfreedom]

there were no o rings to go in front of the lines
????

there are orings used on each line where the lines enter the radiator and there should be internal orings on the fittings where the rear portion of the lines snap into the quick disconnect. the ones in front are available individually for a $1 or 2 each from a dealer and those should have bee included with the lines. the one in the back the whole fitting must be replaced. those are about $8-10 each gm 15043741.
