Radiator repairs in Christchurch

[diesel pig]

Can anyone recommend a radiator repairer in christchurch I can trust to sort out a leak I have in my rad? If the leak was just in the top or bottom tank I would weld it up but it is in among the fins and I am at a bit of a loss as what to do with it.

Canterbury Radiator in Tuam St have fixed a car or two for me over the years. Last time I was in there a chap was building up a custom alloy unit for a customer and it was nice work.

Typically you will find that radiators are like most modern things - throw away now days. So finding a old school enthusiast is the way to go when looking for repairs. Be worth seeing if there is anyone local specialising in classic car radiator repairs.

Skills are being lost yearly as old farts retire. Maybe this plastic bag revolution will extend to other products?

Three years ago I came home to find a pool of coolant sitting under my Honda NTV650. Investigation showed three closely grouped absolutely tiny holes in the radiator finning but no sign of any impact damage at all. My mechanical workshop owning brother in law suggested that the holes were probably caused by electrolysis. So I made up a couple of extra earth straps that went from the radiator fan mounts on the radiator to the frame thus bypassing the rubber mounts on the radiator. And I added half a can of a product called K-Seal that I purchased from Repco for not very much money to the new coolant. Now three years later the system is still completely water tight and I’ve had no problems at all. If your problem is similar you may not need a trip to the repairers.

I had a stone hole repaired very recently in whangarei using a special resin. Cost $40 and was pressure tested etc. Do not put additives in your coolant! Think there is someone in Ashbuton who can weld up for you but I cannot find the thread I made about it...
