HJZ 75 Radiator

Reiner,I bought an aftermarket radiator from 4WD Parts in Perth 4-5 years ago and it as worked well.
It was a bit dearer than others but still a couple of hundred cheaper than Toyota.
4WD Parts has them made to their specs in Taiwan.
They told me they had them use heavy duty welds as the initial batch had leaked(and so did Toyotas in the early 90s)

just buy an aftermarket brass one and have the coolant flushed and replaced every 12 months . about $600 for the brass rad

I put the Aussie desert cooler triple bypass in mine just because I could. The one that was in it was perfect and cooled well. If you really get stuck you can scam that off me. Prob cost about $30 for postage though.

I watched a mechanic soldering up a radiator on a station in the kimberly. He told me the the 75 chassis tended to twist a little and cause the cracking. I would look to fitting the radiator with rubber mounts. A good temporary repair can be made using plumbers epoxy. It will mix under water and wetting the hands will make it easy to mix and shape. It used to be called Ferropre but I forget what its called these days. Its actually good for all manner of repairs. Sticks like .... to ablanket and sets hard as steel. Available from all plumbing suppliers.
