Pinhole Leak In Radiator

mikefoxo

Trying to do up a Grey Fergie. The radiator for the most part is good, one or two little dings. There was a heap of silicone at the bottom of it though and when I pulled that off it revealed two tiny leaks (it looked like the radiator was taking a leak:D). A new one looks to be a bit pricey so I was wondering if there's some product or other that I can either add to the coolant or apply on the outside to permanently seal it? Thanks

Could probably get it brazed, most local garages could do that. Or get a 2 part resin, mix and seal. Would be more for brazing as its more perminant.

I soldered ours and its held up well. Be economical with the heat though as there is a rubber seal underneath

I think there rad seal you can get for small leaks . you pour into radiator and it does the rest. Don't know if it's much uee. Motor factors would have it

used it in my car. 100,000 miles on at still no bother. Just get the engine warmed up and then add to the radiator

Dont like radwell type products. i know few lads who used it and ended up with the car overheating afterwards as it blocked the internals of the radiator

took the radiator off our 35 , it was leaking, brought it to raprad this morning, he said its rotten. 170 inc vat for a new radiator does this sound ok?

I'd think €170 is fine if its "NEW" if he's selling you a "reconditioned" rad then I'd expect it for less..

OP if you’re doing up the tractor you should take the rad out and bring it to a radiator specialist. There are plenty of them around it. They will be able to solder or braze it and, importantly, be able to pressure test it after to at least give you some confidence in the component’s condition. I got a Major rad done for €80 in a specialist called H&Q Rads in Clonmel. I think they’re gone now, or moved at least.
Unless you are good at soldering I wouldn’t bother trying to solder it yourself, the whole thing could start to come apart.

Forget about finding some wonder additive for the coolant because they are only intended for sealing minor drips and weeps on a temporary basis. If the water is pissing out as you say it’s a complete waste of time, IT WILL NOT WORK. People have this notion that such additives will miraculously cure big problems, i.e. chuck in a bottle of “special” goo to cure a blown head gasket.

Don’t bother plastering it up with resins or anything – who knows how long it will last and if it does go, it will undoubtedly go at the most inconvenient time and place possible.

Rang around getting a new one for 150.

Believe it or not, I was stranded one Sunday with a leaking rad and I added an egg white to the hot water in the rad and it sealed it for 12 months!
I had heard it before and said it was worth a shot and it actually worked!
