na6 radiator info . standard/auto/pwr/cooling pro etc

Postby Fatty » Sat Jun 21, 2008 9:13 pm

hey guys. i thought it would be interesting to gather some info about our radiator options.

i'm interested in the capacity (as in, how many litres of coolant held) in the following.

standard na6. na6 automatic rad (reason being is that these are available on ebay from a seller in QLD, very cheap! ) compared to the cooling pro, and pwr.

could be interesting to compare the specs / prices. i am a happy customer with my recent cooling pro purchase. i just thought it might help other people out to compare their options.

but hang on a minute, surely the different size radiators hold different amounts of water?

I would have thought so, however I took this information from my Haynes manual which covers all NA models.

Also confirmed in the miata.net garage.

So na na na.

The differences would be minimal, the majority of the water/coolant is held in the tanks and the engine and piping. The tanks are the same on each radiator, it's the thickness of the core that is different, which really means there is more area for the heat to transfer on. At least that's my understanding.
When results speak for themselves - don't interrupt.

so just curious as i need a new radiator, if anyone has bought one of these CHEAP ebay ones from QLD

If anyone has used it, how is it? just for road use, wondering if i can get out of it a bit cheaper.

I just got a koyo one from the US for about $450 landed.

IMHO its better than a PWR.

I just bought a radiator from an auto NA a few days ago and will fit it hopefully this weekend.
If the standard capacity is +/- 6 litres, I will carefully measure how much more is needed as the core is approx 4mm thicker.

I was close to buying that one on the Sunshine Coast too.

I think...
More coolant = takes longer to heat up
Thicker rad = better ability to disipate heat quickly
every ounce counts

I have a Koyo auto radiator in mine. Fits fine and works as it should, I did not measure capacity but it looks no different to the manual one
