[DeTomaso] 351C Water Pump

Fri Jul 17 10:29:35 EDT 2015

I had a bit of a déjà vu moment when I read this e-mail.  Heck - soooo many suppliers are selling "import" parts, just putting their name on them.  In my recent experience there was the new, hi volume Edelbrock water pump that had coolant and grease drooling out its weep hole, or the Comp Cams roller hydraulic lifters that wouldn't hold pressure.  I fear we all have to be aware that even the "name" probably-Chinese parts we are buying may well be crap.  All I can say is I am glad we found the lifter problem on the dyno rather than in the car.  And that it was the builder who had to get in Comp Cams face rather than me.

With the new non-name-probably-Chinese pumps, I¹d be more worried about the bearings and seals.

That would be my concern, too.
How would you feel if you have to replace it in what seems like too short of a time because it starts leaking?

If it wouldn't bother you then give the off brand one a try.

I had a Milodon, which is virtually identical to a Flow Kooler.  I liked it. 
Very light.  I believe it is injection molded or maybe it¹s called die cast vs.
sand cast.  At any rate, the surface is very smooth, and the aluminum is thinner, which means it is lighter.

I switched to an Edelbrock.  At the time, I had a problem with cooling, and I thought the problem was the Milodon.  I later discovered that I had installed the driver¹s head gasket backward (one of my many bonehead mistakes - yes, I know how the gaskets go - and I also know you don¹t do all-nighter assembly jobs).

I like the Edelbrock more.  The
Milodon is lighter, which is good, but the Milodon feels too light.  The Edelbrock feels more sturdy, and if I recall correctly, the impeller seemed better in the Ed.  I don¹t think you can go wrong with either one, though.

With the new non-name-probably-Chinese pumps, I¹d be more worried about the bearings and seals.
