improving cooling water circulation in '29 engines...
« on: March 04, 2011, 09:47:12 PM »
I'm working on restoration of my '29 biz coupe.  I know cooling the '29 engine can be an issue since it doesn't have a water pump.  Also, summer air temperatures in the central valley of CA where I live could present a challenge to keeping the engine running cool when driving it in during hot weather.  I was wondering if anyone out there has experimented with placing a small 6v in-line water pump alongside the lower radiator hose to force more water through the radiator?  Would this work?  Could it overwhelm the radiator flow capacity and force water out the overflow (thereby making the overheating problem potentially a bigger problem).  It seems to me that such a strategy could work and would not require major modifications.  I would appreciate hearing thoughts and ideas, especially from anyone who may have tried this or other modifications to improve engine cooling.  Thanks.  Kim Mc

Just my 2 cents. 
The model T was made for years and did use a water pump.  If the radiator is truely in good shape and the timing is correct, you should have no problems with cooling.  For extra insurance, place a 4 blade fan or use water wetter.  It increases the heating carring propertys of water (better than normal anti freeze).
I see where model T's could have a aftermarket pump added or a inline pump and it seems that they cause more problems than they are worth.

Kim,

I have driven long distances (30 to 40 miles each way) in 90+ degree temperatures without any over heating issues.  I was actually quite amazed at how well the thermal-siphon system works.  One of the few area’s of the car I haven’t had any issues with.
