Montecarlo Thermostat Conversion Adaptor

Tee piece hose connector for use when replacing the factory 4 port thermostat on later Montecarlo models with a 3 port version and the water pump remains fitted with a 2 port inlet pipe. This adaptor allows the heater return hose to be routed to the water pump by joining into the expansion tank lower hose ~7cm from the tank. Use with conversion hose CO319 directly from the auto-choke take-off point (either Tee piece CO312 or joiner CO321).

High quality machined aluminium.

Use with stainless steel hose clips FS065 for the expansion tank lower joins and FS072 for the heater return.
