i removed the pipe to the inlet manifold jiggle valve and blew hard down it and got air bubbles in the coolant bottle does this mean the jiggle valve is working correctly? I am just about to replace the underfloor coolant pipes with stainless ones and also replace the thermostat with a flow restricting flange and put a prt kit on instead and would be grateful for any advice on getting the old thermostat out the easiest way . I have purchased some car ramps with the low clearance attachments and hope to be able to jack up the other end of the car and put on axle stands to assist with the job again any suggestions would be gratefully recieved
