Now I can relax thanks Phil, you know what I mean....Valvoline.....:-) Speaking of variables, we're both Southerners needing to run our trucks between winter snow and then 40+ summers hauling trailers. What intrigues me on another cooling/water aspect is that some companies are suggesting 82D water thermostats when the US military operating range is 88D ++ :-)

I don't know enough about what difference 6 degrees would make, suspect 2 tents of stuff all after the valve opens, and as long as the flow remains the same, would think the radiator should take care of the rest. I get about 12 - 15 deg C drop across the radiator, so the 6 deg C is accounted for.

On a recent trip towing 1T trailer up a long incline with ambient temps around 38deg my Redarc gauge with the sensor in the top radiator hose climbed to 120deg - red flashing and alarm sounding - slowed down to allow it cool, temps dropped back to 90deg after a few minutes. Checked coolant level in reservoir and radiator after cooling down at end of trip - all normal. May have to upgrade to Duramax viscous fan clutch.

Quick question , just getting fuel and next bowser was a brand new Holden Colorado with "Duramax" logo on the front guard , never knew they had the option , 500 newton meters he said , no trouble pulling the van and said it's the most powerful 4by he's ever driven .
Question is are they any good .

Cheers Phil, just meant that the US military apparently want their 6.5s running at a minimum of 88D op temp and others are suggesting lower thermostats. The yank forum sites I was researching earlier on did seem to consensus GM owned 88D thermostats also.

They have branded the new engines duramax. Duramaz normally means the engine has been made by isuzu. They are only a 2.8 four pot.

Cheers Peter, a big donk Duramax fan sounds great for blokes running belt driven. Any links or sites you've seen mate that show their cfm throughout rpm range? Cheers Mark

Google reckons out of Thailand for Aus too, not sure if that matters or not?

Has anyone come across the autobox conversion behind the td42 tb48 and ls1 using the gen Nissan gear box RE5R05A.
Its a 5 speed trip tonic.

I believe they are oem box in the titan behind a V8 in the U/States.
Std equipment in GT35 skyline, behind 3.5 V6.
I'm also guessing possibly in Elgrand with the same V6 as above skyline.
The Elgrand also came out 4x4 so very possible this is a easy conversion.

My question is this=== are they really any good, Ratios etc
Any good in a patrol behind the LS1 etc ??.

FYI---Wholesale autos are doing this box as an option.

Thanks MB and nissanewby, will double check the specs 2.8 ltr! Don't care much for small donks putting out big HP but then again the wife's 3ltr hand grenade 2002 GU is faster than my GQ .
