Volvo. IF
antifreeze is left in the system for to many years it turns to acid and can attack metal and
seals.
At the age and hours on your engine, Consider changing seals as a regular
maintenance Item
The
Volvo 2003 uses special grommet type seals, Parts 4 engines in the UK sell a kit. I got mine from the local Volvo dealer.
Print off a copy of the manual from the
internet, and follow the instructions because reassembling the coolant piping on a 2003 is an extraordinary metal puzzle. Do not force or bend anything.
