On my '82 truck, I have a small coolant hose that sort of branches out from the lower radiator hose fitting. Right now I forget exactly where it goes, but...

I did some bartering and got a nice new copper radiator for it. It even has one, or two more cores (It's for a later model truck, not sure which one, but it was a 4x4, carbureted, 22R like mine) and is much thicker than mine (Great, because my truck is technically an RV. I need the extra cooling!)

But at the bottom of the radiator, it only has a single outlet, for the engine only.

There is no connection for a smaller coolant hose (For the heater core, I think)

What is the workaround for this?

I think I may be able to desolder the two nipple fittings and swap them out. But I really don't want to if I don't have to.

I know they make in- line fittings with hose adapters, that I could probably use.

Has anyone come across this problem?

 

Is your truck an automatic?

 

No, it's a manual. I see two small connections for what looks like an oil cooler of some kind at the bottom, but I am talking about the tube (5/8" dia or so) that is for coolant. Like for the heater core, or something. It connects to the bottom of the radiator on the same tube as the engine coolant.

 

are you sure this is not the drain hose for the drain cock ? There is typically a "directional" hose for draining the rad


.

 

Are you talking about the hard coolant pipe down by the driver side motor mount? If so, the coolant bung that comes off of it is for your heater core.

BTW, pictures always help because you've got me lost when you started ranting about a new radiator...

 

I wasn't ranting... I guess it could seem like that, but I wasn't. Maybe I should have worded it differently.

Yeah, for the heater core. Is there a way to bypass it? Or connect it somewhere else?

I dropped my phone in water two months ago, and that has pretty much been my camera, so pictures are hard to get right now...

 

Technically, you could just cap it if you can find a big enough rubber cap. Or cut a piece of hose to go on there and thread a bolt on the other end. But then you would have to plug your heater core as well.

Other routing solutions would be to route your heater core to the coolant pipe coming out of the back of the timing cover on the driver side.

What exactly are you trying to do? A little more info is needed for me to assess your situation. Is the motor desmogged? Do you want to keep your heater core? What's wrong with the factory routing?

 

Yeah I just ran into this on my 78. I bought a T. Haven't installed it yet, but in theory, the top of the T is the right width for the large lower radiator hose, and the small stem coming off it is the right size for the heater core return.

So I'm just going to cut my lower radiator hose and put the T in. Not ideal...but better than sending the radiator back, and the hours of searching to find one with that little pipe coming off the lower radiator pipe.

 

What about cutting a hole in the cap on the side of the timing chain cover, and welding a pipe onto it that you can slip the heater core tube on? I think I might try that. Or finding the original Toyota version of it...

 

If you have a plate on the back side of the timing cover, you cut drill a hole and tap it to put a barb fitting on it. However, I have the factory pipe that goes in the place of the plate on the timing cover. You pay for shipping and it's your's.

 

Okay cool. I really appreciate that. Paypal?

 

Yeah, but let me dig it up out of my box-o-parts and take a picture to make sure it will work for you - I think we're on the same page. When I get back in town, I'll post a picture.

 

I just noticed we now have that stupidly annoying thing that links words in our posts to internet ads....great.

Yeah I'm not doing any cutting and tapping. Easier for me to just cut the soft hose and put a T in it.
