Re: Lt1 swap 1966 c10, Coolant Boiling in Recovery Tank.

Just got in from my Hitch this Weekend, Yes it Boiling and Reservoir tank vibrating like a Horror Movie.. I know How to bleed the Air out the system.. Well my Roadmaster sit for about 9 months before I did the Swap, So this Weekend I noticed alot of build up in the recovery tank..
So I flushed the Coolant System with dishwasher soap Cascade (Yes It Worked Great). And as for my Heater Core Hoses I extended them out closer to the firewall and on the return line tied in the Recovery Tank... Fresh Antifreeze and bottle Water.. She's Running Cool Again..
