Yes! This is the fun part...no? Where vision meets outcome (and a few allowances) .
Russ the header tank should feed into the bottom radiator hose, ie cold side of the thermostat.Question for Jac Mac or anyone else.
Motor starts and runs fine now how ever a question regarding header tank input. I currently have the header tank being fed from a heater outlet which is just below the thermostat, there is considerable water movement out until the thermo opens, should it be on the radiaitor side to ensure the water `sucks` back into the system.
