I thought about that as they were lowering it into the garage floor last year. :D Have not actually tried to use it as such yet though. :lolflag:

I am pretty confident now that the leak is just the radiator cap not doing its job properly and lack of overflow tank allowing it to drip all over the radiator misguiding my initial impression. :(

Will put a new one on there with the correct pressure rating to make sure though.

If you overfilled the radiator it will belch a bit.! I have never seen a storm shelter hopefully you don't use it often.,

Re: 1964 GMC 1000 Fleetside
 

Only have to use it a couple of times a year. Ever since the April 27 2011 flurry of tornadoes, if the siren goes off, we get in. :)

Speaking of which...GMCNUT, if you read this, I hope you fared ok last week. I saw where one might have been pushing close to your town.

Well, I "was" confident that it was just the cap. However, as I was leaving for work this morning, I saw a nice puddle of water under the front end of the truck. Water was actually dripping from the bumper where the frame is attached to it (driver's side). I assume the radiator is dripping and running down the frame to the bumper then dripping to the driveway as the pan the radiator sits in was full of water as well. Oh well, another unexpected job/expense. :bbeer:

Haven't had time to mess with it this week, but last night when I got home, I got out teh flashlight. Looks like, in addition to teh cap issue, the left side if you are facing the grill) is leaking around the fins.

Bummer. The aluminum ones are a good option.. here is one in a 60.

Re: 1964 GMC 1000 Fleetside
 

Had not budgeted for a new radiator. Is there a good source online...cheap? :)

Re: 1964 GMC 1000 Fleetside
 

200.00 to 300.00 . That one is in my bud Larry's 60. It was about 300.00. I have used the aluminum in a few jeep projects and really like them. You may also find some one local to check it and maybe repair yours. I will also find out where Larry got his. Barry.

I've seen them at 175 on Ebay, but they're mexican made. Remember, $100 bucks and you can repair the old brass one. They're not as common anymore but easily repaired.

On the turn signal, I got all my stuff out today and started my project but I'm short on some parts. It'll be a couple of weeks before I can order them, but if you're still interested I should have something to ship you a few days after that.

:)

Sorry for the delay!

Now that your cap holds pressure, some weak links can appear in the radiator.
If it is just a couple of leaky tubes, as Barry said, a radiator shop may be able to do an affordable repair. Sometimes they will just "pinch off" the bad tube cutting it and soldering the pinched ends and eliminate it from flowing coolant.

I have a brass radiator in my '72 GMC that was in a race car back in the early 1980s that the fan hit. There are probably 7 or 8 tubes pinched and soldered and it has been in my truck since around 1989!

I am probably going to break down and order the one in this Amazon link for my '55 GMC. $220 free shipping. There may be some radiators on there that will fit your truck.

Thanks for the guidance guys. Dropped off the radiator and heater core this morning for testing/repair. Hopefully it can be accomplished at a price that is worth it versus buying new.

Fetch - got a pm coming your way in a little while.
