Before you use it hook it up some place and try to pump 300 gallons per hour
or 5 gallons a minute through the heat exchanger and the rads. If you
don't have the heat exchanger and the rad yet use a bucket mounted two
feet higher as a guess. Here is a chart of the oil side pressure drop in
an oil cooler. One can relate this to inches of water pressure head.
Hence the two feet. The total pressure drop could be higher as I have no
numbers on your oil to water heat exchanger.
If it does not  pump  five gallons per minute send it back
and get your money back. Power Sport tested one of these electric pumps
and it pumped no where near as much water as claimed.

Ops! I looked at that oil side pressure chart on the oil cooler and I saw 
15 inches of fluid pressure drop when it was really 15 psi of fluid 
pressure drop. BIG BIG BIG HUGE difference. How come you guys are 
not catching my mistakes? 

Lets see if I can figure this out 12 inches or one foot of water is  
about .45 psi so 15 psi is a head of about 15/.45 or 33 feet!!!!
NOT JUST TWO FEET!!!! 33 FEET!!! I had a feeling something was wrong.
The old ball and chain comes in to the office from time to time
destroying my concentration. 

OK Ken, in your pump test set up described above take that piss ant .14 HP 
electric pump and pump the water up the hill 33 feet. That will simulate 
the pressure drop through the cooler alone not counting the heat exchanger 
itself. Probably 66 feet for the cooler and the heat exchanger.
See if you get five gallons a minute to go up the hill. 

GOOD ^%$#%^& LUCK!!!!!!!
