Finally measured my radiator, now I just need input for a replacment...

[CEE1NG_RED]

I have a '67 c10 swb with a '78 350 motor and a TH350 trans. I need a direct 3 or 4 core all metal radiator replacement that accomodates the radiator hoses and trans. cooling lines. My truck does not have A/C nor heating system. I know that 350 motors were not an option til '69 models, but I'm not sure if '69 c/10s have a TH350 trans. Now with that said, do I order a '69 or '78 radiator? And will it be a direct fit on the radiator housing/frame of my '67 c/10 swb and hoses and trans. cooling lines. LMK. Thanks!

I have a '67 c/10 swb truck with a '78 350 Chevy small block motor with a TH350. Now, do '69 350 motors have the same set up as far as radiator hoses connects to the radiator as a '78 350 motor? Also, do '69 and '78 c/10s come with a TH350?? I am trying to get a replacement radiator and would like my existing '78 motor radiator hoses to fit perfectly onto the radiator housing and TH350 trans cooling line. Any insights?? Thanks!!

You could always go to the parts store and ask to see radiator hoses and radiators from both years and compare them. Or get on a parts store website and check the pictures out. I'm sure they are different just because of the body style differences but I'm not 100% sure.

By one for a 69..there are no differences..you will be fine..

[derotoreut]

As far as I know... SBC is SBC. I had a mid '80's 305 cid engine installed in my '69 C20 with no hose connection problem.

You should be buying a radiator and hoses for your 69. You might have to get a thermostat housing for a 69 if the one you have will not allow the upper hose to fit without kinking it.

The lower hose is my concern. The upper is 1 1/2" inlet/outlet and will work with a 69 and possibly later radiators. The lower is another story. The '78 pump outlet is 1 3/4" while the inlet to the radiator is 1 1/2". That's what I need to figure out on what radiator year works for the lower as my pump is 1 3/4" OD. I believe most radiators are 1 1/2". I could be wrong. I'm a novice and learning more about this truck as it was my sole purpose to buying it.

[Lee H]

The stock lower hose will easily work for both 1 1/2 and 1 3/4. There is plenty of give to stretch and compress a little and will seal right up.

I installed a new aluminum radiator that was custom built by Wizard Cooling. I wanted this radiator because I installed a new 383 stroker engine that puts out 465 HP/465 TQ. I also have a Vintage Air condenser up front, so I wanted a radiator capable of handling the heat.

I have a 3-row radiator with auto transmission cooler mounted to it, that I removed for my new install. As far as I know there were no problems with it when I removed it.

Dude, you have created way to many posts regarding this subject. You should be buying a radiator and hoses for a 69. You may have to get a 69 thermostat housing if the one on there will not allow the upper hose to fit correctly. Just go to your favorite DYI store and get a 4 row for a 69, 350 (or any V8 they show) with an automatic transmission.

Agree 100%.

The only difference between the '78 and the '69, is the '78 prolly has a long water pump with the alternator on the passenger side. But the OP should just get the '69 radiator.

The TH350 was the standard transmission in 1969 as well.

I know I have created many posts, but I think they were of different applications?? I'm sorry, but I just want this truck to run. I just found out that my upper is 1 1/2" inner/outer to radiator, but my lower is 1 3/4" outer from the motor and 1 1/2" inner to the radiator. With that said, a 1969 radiator will not do. Guy said it may work with a '73 radiator. I have a '78 motor so the thermostat is a 180* for a '78 that I had added since it did not come with a thermostat!! For now, my radiator is getting fixed at a radiator shop for $20, but I will be on a hunt for a replacement new radiator. I will just have to see how much play I have with the radiator housing and see what measurement works with a 3 core. The PO did a lot of swaps in parts and I am just trying to fix it that's all. I apologize if I posted a lot, but I am a novice and am trying to seek assistance with the forum community.

The '78 has a 1 3/4" outlet. The hose I carry has a 1 3/4" outlet from the pump and 1 1/2" inlet to the radiator. Just need to see what radiator works for me and matches the same measurement as my existing radiator that is getting repaired. Any insights?

[GASoline71]

Go to a radiator shop and measure the outlets of the different radiators?

The 180 degree thermostat was likely stock in the 1969 as well. The 1972 GMC I have came with a radiator out of a 1977 Chevy C10. It was too tall and the PO cut the original upper mounts to "Make" it fit. Looked like hell.

So I just got a radiator designed for the truck. What water pump do you have? I'm betting a long pump, unless the PO changed the '1978 engine over to a short pump. There were never any long pumps installed on these trucks from the factory. Not sure if the long or short pumps have different size inlets. But I'm betting a lower radiator hose for a 1967-1972 truck with a SBC, and a 1967-1972 Radiator will prolly fit on that 1978 engine. Long or short pump.

I want a replacment radiator for my '67 C10 with a '78 350 motor and TH350 trans w/ no A/C and heating. My radiator hose has a '78 upper and lower hose, where the inlet/outlet of the radiator is 1 1/2" and my waterpump is 1 3/4".

Here's the specs of my current radiator.

Core height: 17"
Core width: 28 1/4"
Core thickness: 2"
Tank thickness: 2 1/2"
Radiator height: 18 1/2"
Radiator width: 33 1/4"
Radiator mount (on center): 29"
Inlet/Outlet for the radiator hose are both: 1 1/2"
Core: 3
Metal: Brass/Aluminum

I am a novice and would like to know what all metal (brass/aluminum) radiator would work with this current set up. My concerns are mainly the inlet/outlet (1 1/2") and the mounting/space with the radiator frame housing.

LMK what set up you have that works with this application or at least has a 1 1/2" inlet and outlet. Height and width should not matter as much as long as it mounts to my '67 radiator housing/frame. Much appreciation...thank you.

I have the same aluminum radiator in my truck. Fits good and looks good.

To the OP... you're really over thinking the whole process. You can get any radiator that fits a 1967 - 1972 Chevy or GMC truck and bolt it in... and it will work.

There are many of these trucks on the road today with engines from 1973 and later with different than stock water pumps and they are using the stock radiator that fits the year of the truck.

I agree.

[CEE1NG_RED]

...so what radiator did you both end up getting and was the inlet/outlet 1 1/2"?

Either the stock replacement radiator for the vehicle, or the aluminum equivalent.

I've never measured the inlet or outlet of a radiator or a water pump.

Gary

[bigguy69]

I like that radiator

Same rad here. Fit awesome and looks pretty cool. I'm not sure about your lower hose question though.
