Des Hammill I think is correct in his view that removal of the bleed valve will result in unrestricted coolant flow through that part of the circuit direct to the expansion bottle. It bypasses the radiator and by design the bypass flow does the same and their combined effect according to Des can be ~ 20% uncooled coolant flowing in the engine depending on its RPM.
He reckons that might be ok providing the rest of the system remains good but I personally am in favour of leaving the bleed valve in place. If it is removed I would opt to make and fit the 1.5mm cleanable flow restrictor which he describes in his book. |
