IAE50R – AA
no sudden temperature jumps occur. If the coolant temperature suddenly rises then
there will still be entrained air in existence and the cycle must be repeated.
8) Top up header tank with coolant mix. Refit the filler cap and wire lock if appropriate.
9) Fill the overflow tank with coolant mixture within the MINIMUM and MAXIMUM levels.
10) Carry out full engine ground run
If coolant temperature rises rapidly shut down the engine
and bleed the system again!
Risk of scalding – do not remove the pressure cap from the
radiator until the engine and radiator have cooled.
13.4 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).
