Greetings,

Can someone tell me what is the process to put new O rings on these lines going to both coolers? I see O rings inside the end of the line. I have a 2001 Discovery

Thanks,

 

The engine end is pretty easy, I think it's a 7/8" wrench, pull the line out. The old O ring will either be on the line, or stay in the engine. If in the engine remove it with a pick. Put new o ring on the line and reinstall. I haven't removed the oil cooler end on my Disco, but on a parts P38. The line nut was so corroded to the cooler that it destroyed it. Next time I'll try some heat. I'm sure someone here will have some advice on the cooler end.

 

Thanks for the feedback took it a mechanic and he ended up cutting lines that he did not need to touch, I am now trying to correct his mistake.
