Hi Guys, Bit off topic but need a little assistance - my partners Pulsar Q has developed a pin hole in the rad, as such it looses 500ml a day.I'm only putting the rad cap on one notch so it doesn't build up pressure, but of course it still leaks. Being aluminum, I'm told the rad is too delicate to braze/weld whatever and a new core is the solution. Does anyone have any suggestions for a glue or epoxy that can be successfully used? |

Any good Radiator place should be able to mig weld it , with no trouble at all . I had a Radiator business many years ago , and we used to repair aluminium radiators quite a bit , however if it has one pinhole there may be more , the core could be on the way out , unless of course it was caused by a stone or something ....cheers |

Hmm it was a rad palce that told it was too thin to weld!!!! It's a brand new rad, one of the bolts holding the rad support panel came loose and rubbed a hole.... Might have to try a different rad shop... |

malcom douglas on the world around us (incidently the shows have been re-running recently) told us a few years back to put ground pepper into the radiator. it will float around until finding the leak to block it. i highly do no recommend this as it could potentially block other parts of your engine too. mind you, mal was driving a toyota landcruiser with big wheels and most probably big radiator cores and water channels. |

i also remember seeing a product at my auto-place shelf it says it stops radiator leaks and is in a small bottle about 50mL and says "stop rad leak" the liquid comes in two layers: clear blue and a thicker reddish that you shake |

I have used Wynns radiator stop leak on a few different cars with success but because it is a rub hole I would stick something on the outside. JB weld or similar would be OK. I have patched some very bad radiators with epoxy ribbon with success (fan had chewed out a few fins because the engine moved going over a big jump) |

i ahve recently overcome a similar/same issue with my mini, i would pour the water in, and it would come straight out. go to supercheap or one of the other various assorted motoring stores, you can pick up this putty type stuff that you knead like blue-tack. its worked for me! i bought the cheapest one which was $7 and gave me more than enough putty for the job, i could probably fix 7 or 8 rads with the amount i used! |

There is a product called quick steel about $15 a tube it is a 2 part epoxy but comes in 2 layers that need to be kneaded together until it heats up with the chemical reaction. This stuff dries up in 10 minutes and is hard like steel. Obviously the surface preparation is important so rub back the paint and clean around the pin hole. I have used this stuff on a cracked head on my Gti and its still doing the job after 2 years  and it is also used on some race Periphial Ported rotaries to blank off the factory inlet ports on the housings so the stuff certainly is durable
