Heat exchanger volume

[alex657]

Hi just wondering how to figure out sizes for a heat exchange I was wondering if the size of the heat exchanger had to do with the volume of coolant the engine holds? I'm Lookin at useing a egr cooler off a duramax I have a few clean ones laying around

Pics showing the inside?  How big is the engine?  What HP?

That's a nice heat exchanger and being able to cope with exhaust temps should be fine for coolant.  The core is fairly short though, and it has a small'ish-number of larger-tubes (which limits tube surface area). I'd suspect one of those should probably be good for cooling 150-200HP.

Is it stainless or something else plated\chromed.  Stainless has worse heat-transfer so would de-rate how much HP it could cool.

yeah heat shouldn't be an issue my pickup runs 1600on the egt gauge and that's what the cooler is off, I do believe it is stainless it isn't magnetic... I was thinking about useing 2 of them but maybe that's to much
