Reply to "Fluidyne radiator plumbing??"

Actually, it COULD contribute to your cooling issues.

A clearer example can be seen by going to any water-cooled front-engined car and looking at the way the hoses are arranged. The bottom of the radiator goes to the water pump.

Assuming that you're actually drawing from the top of the radiator, instead of the bottom, if your radiator wasn't bled properly and you have an air pocket in there, then you might not get much cooling as your water pump would occasionally 'gulp air' when you hit a bump or take a sharp turn. That gulp of air would travel back to your block, only to sit there until you raised the right-rear corner to bleed/burp the air out.

Naturally, you're not going to effectively transmit the heat out from the top of the block or the heads to the coolant with an air pocket there. Consequently, it's going to get hotter.

At least, while drawing from the bottom, you'll most likely have fluid in your block until you actually do run dry. Hopefully, your temperature gauge will have warned you long before any actual damage is done.
