==PRRT Part Numbers==
'''PCH001190''' Land Rover cream PRRT kit (including all the hoses and clips needed to make it fit). It is meant to be fitted on a Freelander. ('''''BUY this for an early S1''''')

'''PEL500150''' Land Rover Part grey PRRT kit (full hoses kit, similar to PCH001190 but with a non useable plastic elbow with small takeoff). Not easy to adapt to the Elise. This kit may also be difficult to obtain.

'''PCH003320''' MG cream PRRT kit. This kit is for the MGF which cooling system is very close to the Elise's so it requires less modifications than the Land Rover kit. It's also cheaper and only requires the addition of a piece of aluminium tube as a hose joiner, which can be cut from a discarded tube from the original system. ('''''BUY this except early S1''''')

'''PEL500110''' Land Rover grey PRRT (standalone) ('''''BUY this''''') 

'''PEM101020''' Rover part number for both Black and Cream PRRT (standalone) - the fact two different thermostats share the same part number could cause some confusion.  The downside with the cream PRRT is that (unless at temperature?) the stat won't open below 1500-1750 rpm due to the spring rate.

'''PEL000040''' a metal polo mint replaces the old thermostat in the housing which pulls left out of the water pump before disassembly (BUY this)

'''PEM00020P''' is a complete new dummy thermostat assembly with PEL000040 fitted. It also includes the two O rings for insertion of the assembly into the water pump.
