B5 S4 heater core clogged (Ti Kan)

[Peter Orban]

Hi Ti,

Clogged heater cores on B5 Passats are all too well known!
Consensus is that flushing/chemical cleaning works only for that long and people eventually end up replacing the core.
Read up on heater cores on the passatworld.com in the B5garage forum. Do a forum search on "heater core".
One guy built an interesting clone of a "Blast-Vac Cleaning Gun":
