Does anyone know of a modification to change the original 80 series radiator to a more reliable radiator. Our last 2 radiators have failed on the core edge after extensive travelling on corrigated dirt roads.

assume you have copper? do they fail where the sides are soldered to the top tank?

Radiator is alluminium core with plastic tanks. Fails on side of core about 100ml up from the bottom.

How would you feel about leaving out 1 of the top mounts, so it is located at 3 not 4 points. Trucks, and even my 1944 jeep are mounted at 3 points,- handles twisting better.- assuming this is the cause of failure.
When I was mining, corrosion would cause the cores to move apart, breaking the sides out of the top tank. We only had Landcruisers. The roads were always salty. Corrosion was a real problem and they only lasted a few years.- that was copper radiators, the alloy ones didnt last that long.

Thanks Mattooo, it probably is a twisting problem and we will heed your advice.

according to the local radiator bloke the problem is twofold, the radiators are quite thin metalwise and don't handle the flexing very well and the second problem is that Toyota or whoever makes them uses the minimum amount of solder to hold it all together. Even if you stop the fatigue they will eventually let go as the coolant flowing inside actually wears the metal away.
I found that once the first two tubes on the drivers side had been repaired that it took quite few years before any more failed.

Thanks Peter, these both have been original radiators and have, like yours, failed on the drivers side.

Are you talking the original plastic tank rad or the replacement copper tanks ones? When you replace an 80 series rad any reputable rad dealer will recomend you spend the extra 50 bucks on the copper tank version

Thanks Davoe, this could be the answer to our problem. I'll try a copper radiator this time.
PS where is Cape Culver?

When i bought my 80 I knew the rad was stuffed and the rad guy strongly suggested i spend the extra 50 bucks on the copper tanked rad (I think it is copper) Pt Culver is about 200km east of esperance and can be accessed about 70km east of Balladonia and taking a track south. Or you can do a run along the beach about 70km from Israilite bay to where these cliffs start
