water pump

Run the Edelbrock pump, run a Robertshaw 333-180 thermostat, make sure the orifice is in the block below the thermostat, install a relay upgrade to power the Meriah fans, drive without worry.

The Meriah fans are certainly an improvement over the oem fans, but there are better fans available.

The biggest deficiencies in the oem cooling system are the fans, and it seems that 90% of all Panteras have ended up with the wrong thermostat installed.

OK CFH,
What fans do you recommend ? I would prefer to use the original mounts.

Jeff,

Modern fans use flat motors to keep the packaging as slim as possible. They don't have a long round motor that you can throw a clamp around like the oem fans.

Some owners use the plastic ties that poke through the radiator tubes and fasten the fans directly to the core. A drawback of this method is that the heavier a fan is (more air capacity requires a larger, heavier motor) the more likely the plastic ties will rub against a tube in the core until it eventually leaks. Mounting the fans this way positions the fan blades very close to the radiator core. To realize maximum performance from the fans, the fan blades need to be spaced about an inch off the core, so this is a second drawback to mounting the fans with the plastic ties.

Other owners install brackets across the radiator core (top to bottom) that fasten to the channel that "frames" the core across its top & bottom. Then they mount the fans to the brackets.

One big advantage of mounting the fans behind the radiator is that a shrowd can be installed, and the fans attached to the shrowd.

I disagree with this design. First the shrowd is going to rattle and it will echo like a bass drum.
Second you have reduced the amount of air circulating through the radiator because you have reduced it to the diameter of the fan holes.
This puts all the responsiabilaty on the fans.
