Repairing Plastic Rad...

Got my Polo rad today... only problem is that the small bleed pipe on the plastic housing was broken off and lying in the packaging!

I've contacted the seller (ebay sale) to see what we can do, but not heard back yet.

One of the solutions I offered was to keep it for a (decent) partial refund and I would repair it myself.

Thing is... how best would you do it? Use an epoxy resin to put the pipe back on, or leave it off and get a small blanking plate to bond over the hole (I have a bleed at the back of the engine - tank to head inlet).

Not a great pic...

I used plastic cement (the stuff used to put together plastic hot water pipes etc). I used a small self tapper covered in glue, and it has never leaked a drop!

Cheers guys... the chap has since got back to me and offered me a tenner refund (I only paid £30 for it - including delivery).

Now I know that it's 'do-able' I'll go for that option... £20's not bad for a slightly-faulty but new Nissens rad I suppose!

The plastic taps nicely and you can insert a bolt for bleeding. Did it with mine and it works a treat





You'd be surprised how quickly the sales people at B&Q try and assist you after ignoring you for the past 15 minutes when you try and start a chainsaw

Thanks people!

Will have a look at it in the morning and see if I have enough 'meat' to tap it (its broken right at the base of the bleed pipe.

Yes, Nissens are good quality. Which seller is it on eBay or linky ?

Take a m6 and tap the hole out.
Apply some PU adhesive and screw the m6 bolt and washer in.
put another washer inside and a nut.... job done.
My old rad was like that and we never had a problem with it......

If you don't need the fitting, then screw in a self tapper and some epoxy - mine broke on the way to morocco, and its held ever since.

If you do need it as said you can get a hose barb that should do the job.
