OIL COOLERS AND ACCESSORIES •
1 • Oil Coolers
• Heat Exchangers
£26.73
These technically advanced laminar-flow fluid to fluid heat exchangers can be
installed in main water cooling circuit, or teed off, as in the heater circuit. Their
robust construction protects from leakage in a crash situation. They can be cleaned,
valuable after an engine blow up. Easily installed where lack of space prevents use
of air-to-oil coolers.

These dry sump tanks are constructed from lightweight aluminium and consist of 3 pieces. These can be disassembled for easy
cleaning purposes. A dry sump tank has the purpose of de-aerating the incoming oil to improve viscosity as well as maintaining a
constant oil pressure even when the car is subjected to high g-loads, preventing oil starvation. These tanks also feature anti-surge
baffles to protect the engine from harmful oil surges. The capacity of each tank listed below is the full capacity. As these tanks work
best when they are half full, the tank size is decided by the most oil that you are likely to use for your engine, plus one third of the
tank capacity. Inlet and output ports are tapped with M22x1.5 threads. The 5” and 6.5” tank breathers are 1/2” BSP with adaptors
to 1/2” push on hose. 8.25” and 9.5” tanks have -16JIC ports and breather adaptors for the top ports to 3/4” push on hose.
