I run a fairly modded engine with a standard cooling system with no problems.
Lucky to get to a half after 2 hours city driving. Work and back, just gets to the first mark.
Make sure you run the correct range thermostat for you climate.

You need to be wary of alloy radiators at the best of times. A lot of the cheap ones leak like a sieve... hell even Aussie Desert Cooler has copped a bad wrap from time to time.
There's be no performance gain on a stocker. But they do look sexy. |

Cheers for the advice! How do i know what is the correct thermostat to run for my climate? I live in adelaide and run the stock thermostat - pretty sure there set at 90C or something.
Cos you can again buy "performance" thermostats which run at a lower 81C so your engine is cooler = more power!
Any ideas on running a lower temp thermostat?

Some people rave about the colder thermostat but there is a limit as to how low you can go before it's too cold and you lose efficiency.
From memory 81 or 85 degrees is as low as you'd want to go. |

| A good welded rad wont leak I can tell you that, it boils down to the matrial that is used and and the quality of the machine it self, hence if there is 1 speck of dirt in you nice clean ali (poor grade cheap crap) it will get micro vilocity welds wich are air bubbles ( oxidisation) hence leaks ,, it is a touch and go process when working ali to with hold pressue! I know cause I have a degree in egineering and have had a few years with just tig and mig welding ali, basicaly its not worth it , stick with your current setup , the most positve thing you could do aswell when doing the flush is taking the manifold cover of and physicaly unblocking the water jackets! |

No worries! Point taken guys? Ill stick with my stock radiator!
So any other ideas on the "performance" thermostat then? Has anyone tried one? Check the link in my previous post and give me your ideas people!!!!!!!!! 
Hey trizo, thats sweet man, what degree in engineering do ya hold? Im still studying...  |

about the thermostat: somebody correct me if i'm wrong - not speaking from experience, just theoretically.... i would believe that it's only worth it if you have a stroker, forced induction, or headwork/cam etc? i think that the running temp isn't really too high with a stock engine. Mine is quite low and i have a basically stock v6 so the benefits would be un-noticeable
just a guess |

The stock thermostats there for a reason, if the motors running to cool the ecu thinks the motors still in the warm up phase, so it dumps more fuel into the motor, not only does it cause bad economy but affects overall power.
The average running temp of a motor is between 90-95 and the boiling point is 110 degree's. Differant applications including extreme engine modifications and humidity/temp climate areas can use a slightly colder thermo. |
