Cooling Circuit Through Engine and Heater

Dec 21st, 2006, 15:38

I am currently putting together a '66 122S and need your help! Can anyone direct me to a good diagram or explain to me where to install the hoses in the cooling and heating circuit? In other words, I need to know the path for coolant - any help would be greatly appreciated!
Thanks so much - Steve

Hi Steve
This is something that is easy to get wrong if you don't make notes when you dismantle it, as I can verify. I made this diagram up after finally getting it correct. It is for a '69 B20 but I assume yours will be the same.
The long pipe on the left of the cylinder head is the pipe going to the water pump.
Hope it helps.
