V8 conversion overheating?

Thanks Bilbo,

There is no turbo, plenty of grunt in a 6.2 without the extra complexity of a turbo.
There is no overheating going at the speed limit on the freeway either, just when towing a heavy load.
Unfortunately I only tow on my holiday so I had no warning of the problem. Decided to turn back and investigate first. Replaced thermostats (2 in there) and waterpump, though either looked servicable. Had radiator out and thoroughly flushed it with a gaden hose, no bugs in the fins but the end fins started to perish which got me to the conclusion the radiator is on its way out.
BTW, I did my towing trip to Shark bay after the above investigation, driving to the thermometer. Doable if I stayed under 80kmh, just took a little longer - saved a bit of diesel though :-).
Interesting to read that Brunswick make their own radiators now, might give them a ring but its a long drive to see them. Does your radiator look any different from the standard one? Brunswick fitted an oil cooler in my troopie but used the original troopie radiator with a fixed blade fan.

Klaus,

As this problem has come from nowhere, all of a sudden, after all this time, I'd say it's a more complex prob than just the radiator. However, I hope I'm wrong.

My rad is not the standard rad. It's MUCH bigger than a normal Nissan Rad and was custom made by Brunswicks for the conversion. It's a 4 row monster made like a rad should be made - of brass and copper.

I'd hazard a guess that the standard Toyota rad is borderline for that 6.2 anyway.

Good luck

Aaah- but "better" than what?

Mine's worse than my previous 100 seriesTD 'Cruiser - but better than an Abrams Tank!! (slightly)

aagghhhh - the cost of having fun eh!

Bilbo

He had an after market turbo on the 4.2 diesel that was in the troopy, from memory I think he was saying he gets around 100km more on a full tank now? Dont quote me on that , as we spoke about that many old times, as we hadn't seen each other for 12 years.

Thanks Topcat, I gave them a call to find out the cost. $917.65 was the reply which is a bit tough agains the $465.- quoted locally for a troopy radiator, especially for this newly retiree.

The funny thing is the original troopy radiator worked fine when pulling my boat (~3000kg all up) for the last 5 years and a long towing trip on each year. Even up Greenmount hill and later on the Adelaide hills. It just is getting too old 7 worn out for the job now.

Since I'm not planning another long trip for a few months I think this one over for a while. Thanks to all for the advice.

Gee talk about inflation. It only cost me $650 & that was 3 years ago!!!!!! Cheers.

Yeah - but look at the price of copper these days! Go BHP. Go Rio Tinto!

BHP bought at $13.00

Rio Tinto bought at $10.80

Woodside bought at $2.40

NAB bought at 6.80
