Anyone knows how to remove the "Heating water feed line w/ fuel heat exchanger" on a 603 engine. Mine has a pinhole size in which water escapes so I can't use the car.

Is there a special too to remove the size 32 nut bolted to the block where the LINE is attached to? or do I have to take out the intake manifold to remove this. The part number of the LINE is 603 200 02 52. This is what I want to remove so I can have the leak welded.


Thanks!

Francis

The line should pull out when the clip is taken out. The nut doesn't have to I think. There is usually an o-ring behind there.

Hey thanks there! That would definitely make my life easier! I'll try to give it a puill later. Hope it comes off.


Francis

Worked! Thanks for the great tip!

Can I put grease on the O-ring when I put it back on?


Francis

Yes, a little will do fine.
