Long or Short — which do I need?
The 6.2L heater circuit uses two tubes — a short tube (597223) and a long tube (597222). One routes coolant to the heater and one returns it. If you are replacing one due to corrosion or damage it is strongly recommended to replace both at the same time — they wear at similar rates and replacing both together saves labour costs down the track.
Signs your heater tube needs replacing:
- Coolant weeping or leaking from heater circuit connections
- Visible corrosion, cracking, or damage on the tube body
- Coolant loss with no obvious external leak source
- Heater circuit pressure dropping during operation
Pro tip: Order 597223 and 597222 together — replacing just one heater tube and leaving the other original tube in place is a false economy on an older engine. Do both at once and the job is done properly.
