Replacing 964 Tip cooling lines, er tips please!
Hi, Due to a leak I need to replace both the Tip transmission oil cooling lines that connect to the gearbox. These are items 15 & 18 on the PET page 174 (part no 943 307 070 01 and 943 307 070 01).
Has anyone any tips on doing this? Or is it just remove, replace and then follow the Tip ATF top up procedure in the 'how to' section'. Obviously I'd like to disturb as little as possible.
I also wondered if anyone had lines professionally made up using the original end fittings? New ones are about $280 (just looking up UK prices now)
Thanks, Steve

Just to add... It seems these lines are getting tricky to source so I am going to look at somewhere like Pirket to fabricate some. Does anyone know what is the maximum pressure and temperature of the oil going from the Tip gearbox to the cooler?
I'm guessing it's less than 150oC, as it appears it's hard to get the oil up to 80oC operating temp. Surely it's at less than 2-3bar?
If I can sort a satisfactory solution I'm hoping it'll be of some use to others too.
Those lines must be getting corroded on a fair few tip daily drivers...
Thank you!
