Reply to "Engine water flow diagram/ electric water pump for engine test stand"

don't know, but I got some opinions.

as for flow path, here is best I could find on line

Now for using e pump on test stand

Installing a thermastat will not provide any radiator bypass flow (blanked of port)

It will prevent ANY coolant flow till the stagnet coolant at the thermastat gets hot, so there could be much hotter locations.

so I would think no thermastat and assume you will cycle e pump speed to control flow to radiator and cooling.

you could even have an external radiator bypass valve to allow for a quicker warm up, Hey, even an external thermatat with by pass if you want to get fancy
