heater in bongo only blowing cool air out

[toal42]

hi there, i have a heater problem with my bongo, the front heaters only blow out cool air, and the rear one had a leak coming from underneath wher to pipes go into the rear heater. the pipres are ok and the leak seems to be coming from within the vehicle if you get what i mean. is there a matrix ov some sort in the rear ov the vehicle. these pipes have now been joined together to stop leak. the vehicle has also just had a new water pump fitted. help....

Yep, rear heater matrix in the side panel behind the driver's seat - you can bypass it from underneath - plenty info in "search" - but get the system bled PROPERLY ASAP

Recent replaced waterpump & heaters blowing cold points to an airlock in the system. More than likely - as Dandy says, needs a more thorough bleed.

Proceed with caution until sorted. We don't want any more head gasket failure tales on here.
