RX-7 Coolant Expansion Tank

$225.00

For those utilizing engine swaps or heavily modified cooling systems, this expansion tank mounts to the right side shock tower to provide a high point in the cooling system. On LS engines for example, the highest point of the cooling system must be higher than the steam ports on the cylinder heads in order to effectively vent trapped air out of the cooling system. The expansion tank requires a standard radiator cap and must be connected to the factory coolant overflow tank or similar.

-Capacity is approximately 0.7L.
-Constructed of 5052-H32 aluminum, provided bare.
-Includes 1/4" barb for filler neck. Other fittings must be supplied by customer.
-Bottom port is 1/4 NPT, and side port is 1/8 NPT (1/4 NPT Optional).

Please note, this is not compatible with the factory cooling fan relays, unless they have been relocated,. It uses the mounting holes formerly used by the fan relays.
