 Re: Dimi's Build DRB #68
Dimi,
Must congratulate you on your progress, but have a concern over your coolant line modifications . Are you intending to connect the large upright pipe directly to the header tank. This would be unwise for a couple of reasons; 1. Any coolant added when hot/warm would flow directly into that cyl head. 2. If your header tank is to be the recovery circulation type coolant will take the easy way and not pass thru the radiator along with an imbalance from left to right banks.
How to fix:
Run a small bleed line (3/16" or 1/4" bore) from the 'new' top of your thermostat housing (motor side of t/stat) to the side of your header tank.
Run a 5/8" or 3/4" bore hose from the bottom of the header tank to one of the fittings on the water pump which the heater hose return line would normally attach.
This will allow your coolant to be added and bleed prior to initial start, then even with the motor running to help bleed all air from the system.
