Coolant System Pressure Test
1)
Remove header tank pressure cap and fit a Coolant System Tester (Blue Point No.
SVT262 or equivalent) in its place.
2)
Apply pressure of 17 p.s.i (1.2 bar) to the system.
3)
This pressure is to be held for 5 minutes during which time it must not drop by more
than 0.5 p.s.i (0.03 bar)
4)
Whilst under pressure the coolant system should be checked visually for any leaks for
weeps at all connections (carry out coolant leak check acc. to 13.2).
