Water Neck - Rat2 Gen4/5 Modified
The Gen4/5 utilizes a radiator cap on the radiator in the factory Caldina applications. This modification is the easiest way to get the cooling system ready to roll in your MR2 where the front radiator cap is not an option.
An added bonus with this water neck is the relocation of the radiator cap to the water neck itself and off the strut tower (the factory RM2 location) which cleans up your engine bay and makes things a little simpler, with fewer hoses to leak.
