Is there any way to I can replace the timing belt and water pump without taking off A/C system for 2003 PT cruiser?
The manual says need disconnect the A/C line... Thanks

The Manual will tell you a way that works, If you see a way to replace without damaging anything, I would try, this would save a lot of time not having to get the AC back going.
Good Luck.

It probably could do it without take out the A/C line. But way easier when take out the A/C line and all these brackets when I did it. Basically follow the manual is best way! Lol
