the pump can be tested without removing from engine using a fluid compression gauge. hindi lahat ng auto shops ay meron nito. the Honda casa for sure will have this but of course mas mahal din bayad.
according to CRV service manual, the fluid pressure should be:
with pressure control valve fully open = less than 213 PSI
if reading is above 213 PSI, check outlet hose and valve body
with pressure control valve fully close = at least 1,000 to 1,140 PSI
if reading is below 1,000 PSI, repair or replace the pump
if worn out na ang components ng pump, no use to salvage it since operation is already compromised. replace it as soon as possible.
