heater hoses

[SuperDave]

I have no idea so I'm curious. This sounds like a good set up. I'm just wondering if there's enough coolant flow through this fitting to do much filtering. It's an awful small hole and it seems like it would take a very long time for the coolant to flow through the filter and actually be filtered.

I replace the orfice fitting in the radiator with a regular hose barb, there is enough restriction in the coolant filter to slow the flow down enough where not too much coolant is bypassing the thermostat and eventually cooking the engine.
