I’m looking at starting on this in the next couple of weeks. It’s been bypassed for the last 2 years but we plan on taking the caravan south into cooler weather in August so will probably need it.
I’m aware it’s the whole dash out which doesn’t bother me. I also know there’ll be lots of wiring to tidy up after all the stuff I’ve added over the last 14 years.
I’ve been trying to get some info on which GUs have the heater core with the tap in the plastic pipe. I think mine might be like that judging by info on Patrolapart.
Have also read that the thicker later model will fit with some slight modification to the heater box.
Has anyone replaced the model with tap and fitted the normal pipes? Problem will probably be finding the pipes without paying drug money for whole genuine core.
