Hello,

 I have my water pump housing about ready to go on, Did I read before  that
it is recommended to NOT put a thermostat in, and block up the hole with JB
 weld so that the coolant is always flowing through the radiator ?

I am pretty sure that's what I am suppose to do, I just want to make sure
before I start mixing


Thank you

That is correct Stuart. Block the water bypass and take out the thermostat.
Use a cowl flap to control the engine temp so the cruise drag will be lower
and you will get better MPG.

Paul,

And he may want to drill a small bleed hole at the top of the pump cavity to
facilitate priming.  I recently noticed that the Renesis pump housing has
one.

On a side note, the Renesis WP cartridge and housing, as removed from the
front cover, weigh 4.4 lbs.  The 20B WP cartridge and housing weigh 11.8
lbs.
