Does anyone know the capacity of the radiator for an SPI Cento? I know the cooling system total volume is ~4L but how much does just the rad hold?

I would guess as near to two litres as makes no odds.

Based on 50% flowing through the rad and 50% in the engine/heater matrix once the thermostat has opened.

(the no odds would be what is in the expansion tank at a given moment.)

This would give optimum cooling.

not to mention pipes and heater matrix, but the capacity might be that large, only one way to check...

I meant to measure it before it went onto the car but forgot (BTW this one is not fitted to a cento)

500ml? The end caps would hold ~200 ml each and the channels maybe ~100ml.

I'll try and measure it for you Thursday -- I've one off a car. But remind me tomorrow night.

Cheers John that would be great if you can (it is for the charge cooler on my MX-5 i need a really weak antifreeze mix with water wetter in there so need an idea of the volume so I can work out the ratio I'm just running plain water at the min)

And the answer, measured with the garage's reserve kettle, is 0.7litres.

Thanks, hope i didn't deprive you of a cuppa
