My questions is how much coolant should it take? I have heard 5 gallons, four gallons, etc. When I went to fill her up, it only took in 3 1/2 gallons. With the block, water pump, and everything being bone dry, I wonder if that is enough. I have start it up a couple of times and re-topped it, but it has only dropped slightly. Heater core, and all hoses get warm, so I do have flow. Don't want to run it for too long until I'm sure that is has all the coolant it needs. Thanks.

The radiator can be re-cored to a different thickness, the hose may be longer or shorter, the heater may be bypassed, etc. I just fill'em till they're full. Just make sure you let it warm up enough to open the thermostat, and then top it off. once you have done this you will no how much your setup takes.

I'm into this far enough that if something went catostrophic I'd have to postal or something.  | | | | | Joined: Aug 2008 Posts: 72 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2008 Posts: 72 | I hope to have a video up in a day or two for those who would like to hear the new motor.  | | | | | Joined: Aug 2007 Posts: 462 'Bolter | | 'Bolter Joined: Aug 2007 Posts: 462 | love to hear engine and see truck by the way what is a motor | | |
