Have had pair of Skip's modified water pumps on my 36 Fordor for about four years now. Helped perhaps slightly but always could be better. Anyone had any experience with Drake's new water pumps (part #68-8502-N)? Comments? I've done about everything out there to keep the 36's temp down but it seems like a losing battle in the summertime in Indiana. Thanks.

If increasing coolant flow reduced operating temperature, your problem is more than likely a partially plugged radiator, or one internally lime coated. A lime deposit no thicker than paint will substantially reduce efficiency. As radiator shops are mostly gone, it may be time to consider investing in a new radiator. Here, in Iowa, my '47 couldn't go around the block without heating. After lots of other tries to clean the system, a new radiator was installed, and I can run in traffic or on the hiway all summer with the gauge at half scale using the old style water pumps.

When does your 36 over heat? If it overheats driving down the road, the coolant flow is probably impeded, (plugged radiator, collapsed lower hose, or plugged passages in the block) plugged exhaust or timing problem. The crankshaft gear is seldom replaced when an engine is rebuilt and can be worn just like the cam gear can. Check the gear by examining the driving surfaces for wear. If it only overheats when driving slowly, the fan is not pulling enough air through the radiator or there is too much paint or dirt on the fins. I seriously doubt that changing your water pumps from Skip's rebuilt pumps will help much. The new pumps have a smoother surface inside and are more efficient than old pumps, but there is probably very little difference between the new pumps and Skip's rebuilt pumps. Tom

There are several good comments listed above but let me add one more. On '35s ('36s have something similar), there is a metal shield between the bottom of the radiator and the front crossmember. This fills the gap between the two. For reason I don't understand this panel often is removed with the thought it aids in engine cooling. In reality just the opposite happens. The fan takes the easy way out and pulls the air up from below and not through the radiator thus reducing the effect of the fan on radiator cooling. Again, a lot of good comments have been given but make sure you have the lower front panel or you could be wasting your time and money. Hope this helps. Tom

Thanks to all. Do the back tabs on the shield go above, i.e., sit on the frame or is it simply bolted to the frame from below. Just wondering the proper, original positioning of shield. Thanks again.

This is the shield I was talking about. As you see it bolts from below. Unfortunately, to install it becomes a two-man operation which may not always be convenient. To get around this I "sloted" the bolts on the end. This allows me to use a screwdriver to hold the bolt while I also tighten it. Oh yes, Ford for some strange reason used two different diameter bolts to hold the pan on. I believe they were 1/4" and 5/16". There must have been a reason for this but I can't see any on my car for the difference. So, I just drilled out the 1/4" to 5/16" and everything fits fine. Tom

flatheadfan, I have a 36 and never lealized until your post that my shield is missing. It only overheats in very hot weather and in very slow conditions. This shield is availabe and I am going to install one. If the shield is not there it is very easy to gain access to the distributor from under the car and this may be one reason it was not reinstalled. Just a thought. Don

Flatheadfan & others, you have no idea how much you've helped all of us. I had shield off & on over the years to work on distributor, drain radiator, etc. I even had the thing powder coated!. Back on now where it obviously belongs. Sometimes we can't see the forest for the trees. Thanks again. Ernie Wickersham Avon, Indiana
