Water to Oil Cooler (PRRT)
This water to oil cooler kit is specifically designed to install with our Pressure Relief Remote Thermostat.
an ideal way to keep your engine cool and improve its lifespan and efficiency is to keep the oil at the correct temperature, ideally in the mid 80°C.
On a hot day, without an oil cooler, your oil can reach 140°C causing wear and potential overheating/head gasket problems.
Similar fitment as the air to oil cooler but uses the substantial cooling properties of water to cool the oil.
The main benefit of this system is that you need no air flow over the system so it can be installed in the engine bay with no detrimental effects.
Supplied complete with all necessary fittings including top quality Mocal laminova oil cooler, braided steel hoses, sandwich plate , coupling and new aluminium pipe work if required (early cars only).
Easy DIY installation in just a few hours.
PLEASE NOTE* DOES NOT FIT MK1 WITH TOP ENGINE HOSE RUNNING ABOVE ENGINE
WE CAN SUPPLY A KIT TO CONVERT TO THE LATER LOW COOLANT HOSE IF REQUIRED
'K' Series only
