Anyway the water pump from the old engine was running fine so I’ll just use it and I have that engine to nut out how to get the bugger off/on. Anyway given that this is another job I have never had to do before are there any little tricks I should know about?
I am thinking just remove the air con unit (that has not been re-gassed since the conversion) and just take the old pump out and bung the older but working pump in simple right

Thanks
