I spent a little time Sunday afternoon coming up with a new cooling system. The existing radiator and pump now have a pressurised swirl pot/reservoir that draws from the radiator header tank and feeds back into the water pump inlet (bottom radiator hose).
The reservoir is from a T31 Turbo diesel and comes with a 137kpa cap, which is higher than the 1.1 bar (110kpa) cap that was the only cap that came close to sealing the alloy radiator. The bottom radiator hose is made up from the factory 1JZ hose and parts from a diesel mercedes joined together by a steel joiner I fabbed up.
The reservoir has an overflow hose that feeds the factory overflow bottle that now acts as a catch can for the system.
Hopefully this will see a return to the days of carefree running with no overheating concerns. If nothing else, the system is now self burping, and has a little extra capacity. It should also now seal up properly, with a blanking cap fitted to the radiator, and the OEM quality reservoir and cap
