Thread: Unblocking a clogged radiator

If you're thinking about some sort of chemical or flushing thing I think you're wasting your time.

Pull it out, take it to your local radiator place and get it rodded.
If they say its stuffed then have it recored or buy a new one.

If you're hesistant about spending any money on the radiator, consider that the 300tdi's biggest weakness is that they don't like to get hot.
Hot = stuffed head = lotsa $$$$.
Radiators are much cheaper

The only way to fix a blocked radiator, is to get a new core fitted. You will then have many years of 'cool' motoring. Believe me, I have done it.

I always had overheating problems with 'Fred', after getting thoroughly sick of it and trying everything else, fan hub, head swaps, head gaskets, timing, etc, etc

I fitted a brand new but inexpensive radiator, ------ no more trouble !!!!!

I did get the old radiator rodded out and had the tropical mod done at the same time.
I have put it aside as a spare at the moment, but I'm still thinking that even after getting that work done, there could still be a problem with a remaining plaque build up inside the tubes of the core.
