Radiator Overheat.

if the back side of the belt turns the water pump, the pump is turning backwards.
And is the serp. driving the pump backwards? There could be a mismatch of parts.

Bought as a unit; bracket with a/c, power steering pump and alternator and water pump??

Don't think that could be a problem give it was bought as a unit; bracket with a/c, power steering pump and alternator and water pump??

Bought an $896 Griffin Radiator which was mis-manufactured, wrong brackets, which because I polished the top, they refused to fix the bracket. Long story except to say STAY AWAY FROM GRIFFIN RADIATOR! They have the customer service of a skunk in a chicken house!

if the flat side of the belt turns the water pump it spins reverse of the factory pump. reverse pump might require a special housing. easy enough to check.

I always considered them to be WAY overpriced, and note MANY of them on the resale market after short trials. Also, 3 rows of narrow tubes with an inferior conductor like aluminum is poor design. One CAN design a GREAT aluminum radiator, by making larger tubes, but that isn't what you bought.
You likely should revert to a standard coolant pump direction also. Cooling the heads first does well for short term uses in racing, but might short change the cylinder block at low revs, long term, in hot urban traffic such as Phx in early July. I admit I'm merely speculating, but for a daily driver like mine, I wouldn't DARE try a serpentine belt setup.

I'd thoroughly consider every aspect of a reverse flow system before investing in so much as a bolt toward one. I know racers like to cool their heads first, but many racing innovations DO NOT adapt well for slugging around on city streets.

This in NO WAY PRECLUDES it being WRONG FOR YOUR ENGINE!! Of COURSE the vendors will bundle a UNIT, AND SELL IT TO YOU FOR GREATER PROFIT WHICH IS THEIR SOLE MOTIVE!!! Be WARY of LOGICAL FALLACY HERE!
The only design consideration you've shown us regarding this unit is that the vendors wanted customers to buy their product. They made it MORE APPEALING by anticipating the normal difficulties with transforming a V belt accessory system to their serpentine accessory PRODUCT. The vendors DIDN'T CONSIDER THE IMPACT THIS PRODUCT MIGHT HAVE ON YOUR ENGINE OPERATING IN A HOSTILE ENVIRONMENT SUCH AS PHOENIX ARIZONA IN JULY AT RUSH HOUR!
I HOPE I'm WRONG, but you MIGHT have purchased and installed the means to utterly ruin that engine if you're not careful. That Griffin radiator by itself goes a fair way toward that.
You are having a large overheating issue so anything in the system, new or old, is suspect.

we actually don't know yet what type of system this is. both types are available with serp. belts. single belt is reverse, multiple belt normal. even if the pump is reverse rotation, the housing accounts for it and the coolant flows normally.
Seems to me that there would be reverse water pump and/or housing for reverse direction marine engines.
Just thinking out loud... No idea if they have that or not.

i'll ask you this, does the heater core act as a by-pass on his engine? i see that it's an Arizona car. maybe the core's not hooked up but needs to be.
No, I've run a lot of big block Mopars with heater hoses looped or even the outlets plugged and no difference.
In fact, I use a small ball valve on heater hose of my 300 to limit the hot coolant from circulating through the heater box, which lets my AC blow a little colder (in theory anyway LOL)
Of course, the redneck survival manual will tell you to run the heater to cool down an overheating car. Been there, done that.

AH, THANK YOU for THAT clarification! Let us pray for the OP that he isn't attempting reverse flow w a street car. I thought about it some yrs ago, but I looked into things, and decided it wasn't right for a family ride.

If Griffin’s radiator proves to be as good as their customer service, I’m screwed!

Absolutely everything in the system is new. Everything.

No reverse flow, first thing checked.
