i see flow kool has a polished nailhead water pump. it has a 5 vaim impeller. i seem to remember some discussion on 5 blade moving too much water. was there ever a conclusion to that discussion or is three blades the best for cooling? john
personally, I would go with the 5 vane.... because the thermostat is what actually controlls the water flow...I dont believe that a pump can flow too much.... If the radiator is big enough and clean, the thing will cool.... i use the railroad method and it works.... Way big radiator+ plenty of fan+ good thermostat= cool engine.....:laugh: If the engine gets too cool the thermostat will close some and bring it back up to temp.... and if it starts getting hot, right away i know that there is a problem and i shut it off and start hunting the problem....long before there is any damage done....
Ditto the above. We did run into the "too much water flow" back in the day when we raced 255 inch Mercury flatheads that ran no thermostats. We wound up cutting off every other pump impeller and installing flow restrictors where the thermostats would have lived. Thermostats were not used as we ran no fan. For anyone who isn't familiar with the flathead, it was essentially two separate four-cylinder engines sharing a crank and cam. There were two water pumps, two thermostats two upper and lower radiator hoses, and in the earlier cars, the radiator was split, as was the distributor. The coolant was not shared between the two banks of cylinders in the engine.
i pulled my flow kool water pump off when i went to refresh the motor, wonder why the motor was over heating. the flat disk came off the end off the impeller and got mangled up and was stuffed in the passage that goes to the radiator hose. blocked at least 80% of the opening.
Gsgtx how long was the water pump on there? Are you saying it was a bad pump? Or did it just wear out? john
the pump itself never went bad, just the flat disk broke off the welds. well it started running hotter after maybe 500 miles or so.
The disk came off the pump? Three impellers or five ,... are not going to work with such a restriction.
It reminds me of the MEL engines. With three thermostats of varying temperatures.(140* in each head and 160* at the water manifold) Later, The two secondary thermostats in the heads were eliminated. But, baffles needed to be inserted in their place. Or, inefficient cooling would result. As well as erosion of the cooling passages. Over engineering at it's best. A huge radiator made up for a lot sins
You cannot have a radiator that is too large. BTW: I think the aphids have gotten into what passes for my brain. What's an MEL engine?
I got that. It's what I'm saying. ---------- Post added at 07:46 PM ---------- Previous post was at 07:36 PM ---------- MEL = Mercury Edsel Lincoln. FE = Ford Edsel The MEL was used in Lincolns and marine applications 1958 through 1967 and into 1968. Including the Mercury Marauder with 3x2 barrel. Dad was a big Ford guy. Flat head Fords and Lincolns. Over the years, Dad owned three Buicks. But, he had 3 flathead Fords, 6 MEL Lincolns and 10 other (later) Lincolns.
My dad was a huge FOMOCO guy too. In fact, he never owned a car not made by them. I remember a '40 sedan, a '50 sedan, a '53 wagon, a '55 Mercury wagon, a Mercury Turnpike Cruiser, a '59 T-bird, a '58 Lincoln, and a '60 Lincoln. He died in '64. He thought that detergent oil was a tool of the devil, and had lifter trouble with virtually every one with overhead valves. I never could convince him to put the HD oil that the manuals specified in his cars. My Buicks (running on 10-W-30 HD oil) never had any lubrication-related problems.:grin:
I found a fomoco flathead in a 49 lincon I think it was and a flathead caddy motor layin in the dirt in a junkyard out here in colorado
Dad had a few Cadillacs between Lincolns. 3 of his Caddys were ohv. But, he had a '40 Cad flathead. That '40 flathead had some torque. Most of the time Dad drove that car without using first or second gear. It would go from a standing stop smooth as silk in third gear. ---------- Post added at 08:20 PM ---------- Previous post was at 08:14 PM ---------- Here's an interesting read on Lincoln v-12; http://www.rodauthority.com/news/hot-rod-lincoln-hh-flatheads-v-12-lincoln-engines/
