Help with coolant upgrade
Hi all, I finally felt a slight coolant leak when I did a 1300mile road trip on my 2015 Range Rover Supercharged. I carried some coolant as I had to fill before I start. Looks like its leaking from the plastic hose outlet from cylinder heads to the heater. I got the supercharger and all removed and all of the things I am about to swap, except the thermostat housing. I am trying to get the thermostat housing off but its hard to get it separated from the plastic piece between the radiator hose and the thermostat housing. Amy ideas on how to get it removed. Also I am not getting OEM ones(except the gaskets, seals and washers) as landrover is still selling some of them in plastic.
The other thing I want to ask is the PCV system leaking oil. Is it common and what is the fix? Complete valve cover replacement?
