i must admit, on my first TD5 D2 when i got it, it ran at 86-88 then after i fixed the head and all new hoses and thermostat it now runs at 91-93. pretty much the same as you now face. i put it down to the cooling system not being right beforehand, not the other way round.
i am just going through the same process on the 2nd car, so will wait and see the out come on it. it ran at 87-88. will see how it all comes after head is fixed.
i was contemplating getting silly and port matching the heads and and manifolds and getting the valve seats smoothed for flow , but then i realised its a deisel and i am a bit older now and don't really need to waste money on that stuff anymore :)
I must be as silly as you Rosscoe, as i was thinking of one of those gadgets that lets the computer run more boost:twisted:. But perhaps i should just let it all settle in for a while first. Thanks for the help mate.Quote:

Intake to head won't really make any noticeable difference unless its as badly matched as the V8's are but never seen the porting on the intake on a TD5.
Shortening the runners would make a difference to turbolag however.
Biggest problem is they are only a 2 valve per cylinder setup...

i don't have a problem with 2 valves per cylinder, i reckon it should have about another liter of engine capacity to push a 2 tonne vehicle though, even turboed :)
i know i know get an isuzu
Mmmm.... 4HE1TC...... time for a 9" front & rear, 4" propshafts, new trans tunnel to take the matching box & transfer from the donor truck......Quote:

Temps
when not working on the freeway mine runs at 84. Small hill puts it anywhere up to 87. When working hard and hills it can reach 91. I have tested it repeatedly.
dang
mine goes to 93-94 going up perth hills if its is hot outside
Just a quick op date. Drove 800ks towing a trailer 400 of those had a series 3, 6 cyl ute on the trailer and the td5 never missed a beat. The ambiant temp was at 38 deg, the car temp rose to 95 at one stage but mostly sat about 88. Very happy with the out come.
I would like to thank every one who had some imput through the head gasket job. Its greatly appreciated.
Cheers Jim.
Good outcome Jim, well done:)Quote:
