Re: 1972 GMC Farm Find LS Swap

Started the task on plumbing the cooling hoses etc to the radiator. After several trips to the parts stores I’ve got a makeshift set up until I can get a better reservoir, as the one I intended on using had a small leaking crack. Ultimately it’s fine because I wanted to use a different reservoir other than the bulky factory NBS truck one. So for now, I have hoses straight from the firewall to the water pump w/o the “T” in line. In turn I routed the steam hose from the TB to the 1/4” nipple below the cap.

Filled the system and heard the familiar sound of liquid hitting the ground.....and a lot of liquid. After fretting on it possibly being the head gaskets, I discovered the coolant crossover plates had no seals or orings. Quick trip again to the store alleviated the leaking fluids. Got the intake back on and all the hoses connected again.

Now on to wiring the fans and we will be ready for the drive!
