Radiator leaking....i'm gonna cry

[Shinigami]

So my rad has sprung a leak on the way home from work today, no idea why or how, rad was already bent so might be the eventual result of that.

Is there any way to repair it or am I looking at a new rad? cheapest i've found is £125 not good when i'm utterly skint due to having to move house soon and most ikely be unemployed for a short while

radweld

[Shinigami]

does that stuff work well? or is it very temporary? apparently putting black pepper in works aswell temporarily?

Or egg white, but it would be a lot better to get radweld or if it's an obvious leak can you solder it up?
Radweld will only give you a few weeks most likely, although you can do it repeatedly it's best considered temporary while you find an replacement.

JB weld!

Had a pinhole leak on the rad of an old bike, this fixed it and I believe it's still fixed now, just stuck a blob over where the leak was.

Used it years ago and it worked.

radweld is ok, brazing or soldering would be the permanent fix.

used it in 100's of fucked cars with no ill effects.

alot will depend on where the leak is, if its in the core, much harder, if its in the frame or external pipe connections, more options are about


the one rad additive i would recommend is K-SEAL, or possibly the new radweld plus

[Efes123]

Just get it re-cored. I got a Jag rad (which is rather large) done for about 60 odd quid. It's a damn site cheaper than getting even a second hand one.

This worked for my badly leaking rad, saved me spending...

Bought a tube of 'metal putty' . Worked a blob of it into the rad grills using one of those wee wallpaper seam rollers. Let it set over-night

Job done. Was a nice cheap option that worked for me after the rad weld kept failing after a few days use

[Shinigami]

not sure exactly where it's coming from, it's the left lower somewhere, not sure i'd trust radweld for anything in the long run by the sounds of it a new rad would be best :/

this is the leak when i stopped when i got home, it was coming out way quicker when i stopped at the lights earlier though

If you can afford to buy a new raditor then do it, if not solder/radweld etc...

I thought you couldn't get new one

[charlie74]

that aint a leak, its a drip

chuck some k seal in it and it will hold for a long time, certainly long enough for you to not worry about finding the money for a new rad

i used k-seal as a temp fix on a weaping headgasket on a toyota 2.4 diesel, and 2 yrs later it was still ticking along

if your still keen to get a new rad, ask around at your local motor factors if they know of any radiator recore specialists, that may work out much cheaper, and you will get a much better quality core at the end of the day than a cheap import

[Shinigami]

cool i'll get some sealer in it then, do halfrauds sell it as not sure where else round here would

It does drip a lot more than that when hotter though, lost 2 litres of coolant riding home from it

I had a leak about the size of yours; not massive, but still noticed the damp patch on the radiator and it dripping when i parked up.

I stuck some radweld in there back in march and thats done the job and is still holding strong, so i'd recommend it.

[Shinigami]

was thinking a new one was probably the wise way to go, mainly due to this one being bent and worn (it's done 80k miles)

the leak is much worse than it looks here but rad had already cooled a bit by this point like i said, lost 2 litres over a maximum of 30 minutes..

will try the bars stuff from halford tomorrow first, if it doesn't work looks like the credit card will have to come out of hibernation

halfrauds dont usually sell k-seal but worth asking.. but yeah get bars leak, instead of radweld

My car is 3? 4? years into a Radweld bodge. Just do it.

i had a hole in my busa's radiator about 2 years ago , i stuck a bottle of k seal in it & its been fine since

[Shinigami]

put a shot of radweld in this morning, was still leaking while the engine was idling (ran it for 25 mins) let it cool down again, just been out for a short 10 mile ride and no sign of leaking now no idea how long it will hold up but will give me time to sort out finances a bit more and source a cheaper rad

Keep your eye open on the Hornet's Nest - they crop up there from time to time.

[Shinigami]

there's some on ebay from china for £80, no idea on quality with them being from china but I reckon the people selling for £125 in the uk on there are selling the same ones they've imported themselves

manufacturing quality of the chinese ones wont be that bad( its not that hard to make a rad) but the quality of the metals etc used.... who knows
add in the risk of damage by the carefull shipping handlers...

up to you, but i would prefer a uk seller, even if it was a chink part, at least you would be on uk soil and covered properly by sellers regs

i guess the real question is how much longer do you intend to keep the bike, i would expect a chink rad to last at least 3-4 yrs if not repainted before fitting
