Model T Ford Forum: Forum 2012: Leakless water pump parts change

Since a parts change just started in May, maybe no one has mentioned it on the form.

I have just bought a leakless water pump. It no longer comes with a thermostat. In its place is an Aluminum Head Saver to be installed in the neck of the radiator.

The instruction sheet explains this about the Aluminum Head Saver. “As of May 2012 we have started to include our “aluminum Head Saver” with all water pumps and discontinued including the thermostat that had been included in the past. We found that sometimes the thermostat contributed to overheating in cooling systems which had marginal radiators and that failure to use the Aluminum Head Saver sometimes led to premature corrosion of the aluminum water pump casting. So we included the head saver instead of the thermostat.” Langs has the alum head saver separately.

Don’t be a smarty like me and saw off part of the flexible hose because ‘you can just visualize’ the problem of installing it in the apparent shorter space between the pump and the radiator lower neck. It seems to be too long. But you have to have the flexibility because the hose has to curve due to the angle created by this longer pump. Langs had and extra one in stock for dummies like me.

The instruction sheet asks you to not turn the water pump until water is in the system because of dryness of the internal parts.

Both the water pump and the little piece of metal are items that will make your Model T less reliable. Just leave them on the shelf, they don't help your cooling system at all.

Way to go Royce! Just trying to get something going - it is a quiet night here in Louisiana.

hes right, unless you live in constant 110 degree weather a water pump is a contrivance.

if you are overheating in normal operation it indicates another problem, build up in the block, build up in the radiator, or your engine isnt running right.

if you have a radiator that just wont work after rodding it, boiling it, flushing it etc. then a water pump can help hold you over until you can buy a new radiator.

It commonly was above 110 and even 115 degrees when I lived in Tucson. No one there needs a water pump, and my Model T's never overheated in Tucson, even when climbing Mount Lemmon in summer weather.

On the Texas T Party tour last week more T's were rendered inoperative by water pump failures than by any other cause. On the first day alone two of the "leakless" water pumps became seized "turnless" water pumps, causing the affected vehicle to overheat violently. At least four Model T's out of the 103 in attendance had water pump failures that caused overheating.

So if you have an aftermarket cylinder head with overhead valves and really tiny water passages is it still a bad idea to have a waterpump? Because the waterpump might stop it overheating.

when its 105 110 here, which is rare, my car runs pretty hot, it wouldnt take much to cause it to boil, IE sitting in traffic, but so long as you keep it moving it holds its own, but if i lived in it all the time i would run a water pump, just so that i have the assurance that if i sit for a while i wont be on the brink of boiling over.

i ran a water pump for a while because i thought i needed it, i never had a problem with it. most problems come from operator error and not knowing how to work a packing. this of course is refering to the water pump i was using, which is very similar to the repro sold macs and the like.

if you are running a high performance car, you will prolly need a water pump. so no harm in running one. im certain if you can build a overhead valve hotrod T engine then you can make a packing and a couple bronze bushings work.

if you have special circumstances, run one. but remember not all pumps are created equal.

ALSO, not only the cooling system will make you overheat! if you are running your engine too retarded, or if your carburetor is adjusted too lean or too rich your engine will run hotter.
