ok so my new lwb 1ltr keeps heating up
anything over 70 km/phr for a sustained period over 30 degrees and the temp goes up to 3/4, same when it sits at the lights for extended periods.
heres the thing its got a new head, new radiator, new thermostat, new water pump, tried adjusting the timing
other than shoving a 1.3 rad in what else could it be ?
oh and fan and shroud are like new

I had the same problem, crap from the block was blocking the tubes in a new radiator.

Either have a look through the filler cap in your radiator or stick a stocking over the top inlet hose drive around a little and have a look.

mmm it all looks spotless to me, and its all brand new

Your block could be full of crap.

[MrRocky]

mmmm

[madmacca]

is the gauge accurate ?

is the fan surround in good condition ?

does it cool down again when you slow down or does it stay hot ?

[MrRocky]

its all brand new, the gauge is new
just flushed everything and it was a tiny bit of dirt but thats it
i'll take a spin down the hwy before the rain gets here

[MrRocky]

nope still hot

[madmacca]

maybe try taking the thermostat out , I have had "new" thermostats fail before

are you getting flow through the radiator ?

btw just throwing ideas out there mate you have probably checked all the stuff i can think of

[MrRocky]

yeah the thermostat i took out was brand new and i replaced it with a genuine one, same prob.
just ordered one of those $150 alloy 1.3 sierra rads from ebay
ive had sucess with them in the past, and i would have needed to upgrade later if i do a conversion anyway.
now i play the waiting game

[youda]

if its only going up to 3/4 have you checked the radiator cap?

[royce]

on mine I found shrouding the front of the radiator to teh grill helped heaps, stopped the air going round at speed and hot air circulating round it sitting still
