60-66 Radiator Over flow tank

[jbgroby]

Hey Gang,

I’ve been speaking with another member (Pete Chronis) on what was the factory correct radiator overflow container for our 60-66 trucks. I have ordered a generic 2”x16” container to catch my water expansion when needed for now.

According to what we can see or find, most trucks (65-66) came with a larger radiator overflow tank. Classic Parts #78-416 and is reported to fit ’41-54’. This mounted on the right inner fender next to the battery. However, it’s the same design as what was used on a 65-66.

Does anyone in the group have better information?

I don't think I have ever seen a truck of this era with a factory overflow tank. Most everything has been just vented. Even my '72 El Camino doesn't have one.

Well I had to change my response because I found the picture posted below.
Still I have not seen a chevy with one even on our factory a/c trucks.
Maybe they were a dealer installed item.

I started thinking about it and had saved this picture some years back of this 66 GMC Suburban with Factory Air Conditioning. Not sure if the tank is factory or an accessory.

I'm not sure if you are looking for a factory overflow tank (I've never seen one) or one that looks factory and fits our trucks. - If you are looking for an overflow tank looks good & fits our trucks you might look at the ones for the Ford Trucks. They are a Radiator Over Flow/Windshield washer combo and the cut of the tank fits the angle of our inner fenders almost perfectly and as a plus you can now add windshield squirters at a later date if you want. This is the set up I went with on my 64 C-10. I moved the horn relay and voltage regulator to the other side of radiator support using the original mounting holes and grommets for both. I later though did go to a one wire 120 amp alternator. I got mine from the wrecking yard BUT you can get it brand new from Rock Auto for $28.00 if you prefer to go that route.

Yep, I know a Ford Overflow/Windshield tank & pump combined with Ford truck windshield squirt nozzles, Ford Bronco wiring conduits for my power window & power door lock wiring, a Lincoln mark VIII electric cooling fan with a Volvo fan relay, Jeep Cherokee door check stops, Jeep Cherokee footwell lights, Chevy Van tilt column, 1964 Chrysler A/C vents and soon to be a 71 Cadillac emergency brake assembly that will automatically release when I drop my C-10 into Drive or Reverse. I don't shop at Jegs, Summit, Speedway etc., etc., I do my shopping during 1/2 off days at Pick N Pull. Besides my 64 C-10 I also own a 62 Pontiac Catalina, Tri-Power, 4SPD & 8 lugs, a 1971 M&M Hearse, a PT Cruiser 284,000 miles (my daily driver) & yes even a 06 F-250 for hauling stuff.

Chevrolet did not offer an overflow tank for 60-66 and I cannot find any supporting info for GMC. The one you show Jake is a reproduction of the factory one for Chevrolet of the 40s and 50s. The one in post 4, I dont believe to be factory judging by the mounting bracket. Pretty sure thats Steves Suburban.

Not to hijack the thread, but how do you activate the washer pump?

If you are talking about the windshield washer, it's a button in the center of the windshield wiper switch.

Brad,
As LostMy65 stated there is a pushbutton in the center of the windshield wiper knob on trucks that came with windshield squirters from the factory. I did buy the correct switch off eBay. The washer pump is built into the Ford Overflow/Windshield washer tank. The pump also is still available from Rock Auto new. I ran an ignition on fused hot to the pump. The push button squirter button completes the ground activating the washer pump.

My 66 has what looks like an add on of unknown vintage.

I have the dealer truck data books for 60-66, a radiator overflow is not listed for any year as a factory option or an accessory.

Do you have any of the GMC Data books ?

[oldusafmsgt]

No, sorry, I don't. The Chevy data books are hard to find, and can be expensive, and the GMC books even more so. The last GMC book I saw, a 1963, sold for $300.00, and that was 4 years ago.

[60-66]

Oh I know , I have every data book 1955-1970 but only 4 GMC data books. Priceless information that took a long time to find. But to confirm what you stated , the GMC and Chevrolet parts books do not list a radiator overflow can .

[oldusafmsgt]

I have no idea what the GMC books say about a radiator overflow. In my 60-66 Chevy data books, I can't find a reference to one, either as a factory option or dealer installed accessory. I'm sure, like rear bumpers those years, dealers probably offered some aftermarket catch can if someone wanted one.

I went with an early 1990's Toyota overflow tank. Nice and narrow and mounted it on the driver's side radiator support.

Interesting, I wonder if it works properly (return suction). I like the idea.
