Coolant leak from bulkhead / firewall area
As title
2005 UK spec D5 auto.
I have a coolant leak! - This is dripping from an open ended rubber pipe on The RHS (looking into engine bay) 3" above the gear shift cable. About 1/2" diameter It seems to go back under the heater (towards the middle of car)
Carpets dry, leak reduces when heating turned off. No leak around heater connections on engine side
My assumption is that the heater core is leaking from the top, and then draining into the AC condensor drain. Is this even possible??
Cant think of any other source of the leak!
Before I start pulling the heater core, has anyone got any better ideas or confirmation that this is the case?
Thanks in advance
