I have a B-series engine and I eliminated the air conditioner and heater. There is one hose that used to come out of the head and into the firewall and one out of the firewall into the block (Or is it the other way around? Dont remember.) Of course them being coolant to heat the air. The question is, after eliminating the hoses going into the firewall, which option is better, to just plug both or run a hose from one to the other(the head to the block)?

Thanks for the reponses in advance.

 

you can do either, preferably loop them though just to keep some flow going

 

I looped mine, been running for years like that.

 

I looped mine for about a year when my heatercore broke until I replaced it. Worked fine, if your looping them, keep the heater control valve open.

 

Thanks for the responses bros.
