If the coolant level drops there, it is too late. The pump will cavitate very very soon. (assuming is the stock pump). I would install it in the expansion tank or overflow tank. When the coolant drops there you will have more of a chance to head back before the pump gets exposed. Hi Buly, All correct of course. The hole I have available is in the upper part of the wp housing, well above the pump level. It's similar to the location where Mazda put it in the FD. I do agree that it will be better in a separate tank, but I'm trying to avoid yet another rev-4 complication if possible. The level switches that I've found won't come close to fitting in the housing anyway, so a custom (because nothing I've found will fit) aluminum expansion tank may be the only option.
