Leaky rad drain

Recommended Posts

My Spit has a full width radiator which I have realised is leaking around the insert the drain tap screws into. Thought it was the tap thread itself first, so refitted with PTFE tape, but definitely around the insert.

During normal running at this time of year it was just a slight drip but while working on another issue and the car getting hot in the garage, I noticed steam coming out, so needs sorting.

 

Just wondering if anyone has experienced similar, what the insert is made of, can it be prised out and refitted with some sort of sealant or will it disintegrate?Alternatively, anything that might be up to the job of a permanent repair applied to the outside?

job for a good clean to bare brass and a small blow lamp with a run of solder  keep it local or you can de solder the bottom tank  ( rad drained )

like a cooks torch often in aldi or lidl quite cheap

you could try K seal or Barrs leak  as a temp leak fix wich will seal up seapage like that till youre ready for being more ambitious .

Ah, have taken a closer look, scraped some paint off and can see what you mean. I should be able to solder that. Thanks Pete 👍

thats a good job  , think what you have saved  and not needed a rad specialist or worst 

a quick test will prove its succesfull

Yes, hopefully get a chance to refit the rad tomorrow then all should become clear.

Hmm, refitted the rad enough to test it and it's still leaking. Not as much as before but definitely a steady drip. 

So removed some more paint from the bottom of the tap boss and found it has split down further than I had noticed.

So back to the soldering

i would have drilled a small hole in thend of the split to stop it propergating 

maybe next time just shows acarefull ook see can solve with a fairly simple  DIY repair  

good to see its holding up

Yes, in hindsight drilling a hole would have been a better idea. Oh well, have to keep an eye on it. I haven't repainted it yet, just in case.
