Would this work---temporary heater core hose routing?
I want to start the truck this weekend, to run the engine. It has a new heater core, new radiator, and I have been finding the right hoses. I won't be driving it this winter, so no reason to get fluid into the new heater core. Could I just run a short hose from the water pump side to the return, just a short loop, leaving out the heater core?

Sure. Some people don't run heaters at all.

I think they're different sizes, one is 3/4, one is 5/8. Can't remember which is which, and my truck is in pieces, but I know they were different in mine because the heater core pipes are different sizes. Although mine is an AC truck and the heater core is different than a non-AC truck heater core.

The bigger diameter is on top.

![]() *Truck is actually up on blocks, there is too much to do, this is only to get anti freeze back into the washed-out water jacket of the engine. I have the heater core in as advised on here, bigger opening on top, and I know they switch when hooked up to the engine (upper to lower, lower to upper). I have had the problem of the 5/8 inch hose fitting over the flare of the upper engine side opening. Fortunately, the guy at Advance Auto suggested and sold me a 3/4 inch to 5/8 inch reducer coupling. I can use that and make things work pretty well I think. I just want to start the engine.....the truck won't be driven, it won't leave the garage before spring at the earliest. |

You can stretch the 5/8" hose over the 3/4" nipple as a temporary measure, to get the coolant to circulate. Note that you can also buy caps to put on the fittings instead of having a hose recirculate the coolant. Or just put plugs in where the hose fittings are now.

Thanks for the suggestion of plugs, I bought two yesterday but now I've decided to just loop the 3/4 inch line from water pump to return. That will get my water jacket full and I won't have to cut off any short pieces. I'll test fit all hoses now so I can be ahead of that task come spring. |

I got it! Sorry, no pics.
I was able to force the 3/4 inch hose over that big flare. ![]() |
