Flowkooler high flow pump #1622 for Pontiacs with the 8 bolt pattern has significant design improvements to achieve higher flow rates for improved cooling.  Taller vanes bring the shrouding closer to the mating plate surface and additional precision machined vanes with a thinner wall provided a greater volume to the impeller's eye.  The incremental vanes are balanced and carve up the workload to conserve horsepower all while achieving greater flow rates, higher head pressure and a more efficient flow. The impeller's color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Pontiac engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

A Note on plates and gaskets: 

The 8 bolt water pump used prior to 1968 has two steel plates in the timing cover behind the water pump. The center hole draws the fluid in and the plates route the flow to the left and right side of the engine.

1968 used a single divider plate and also had two additional rubber gaskets/rings that slide into the holes and assist in sealing and aligning the divider plate.   Absent rubber gaskets the two divider plates may float inside the timing cover and some people have report a "rattle" sound.  A work around proposed online suggests using a "dab" of RTV" to mitigate sound.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Powerful!
Color: Lux Galaxy, Size: Rechargeable Z1 Motor Max
This thing is powerful and works great! I was hesitant about some of the negative reviews, but this is worth it so far. I use it every day and haven't charged it in the week that I've had it. Some people complained about turning it off.... It's not that hard. Just hold the button down for a second or two and it shuts off, no fuss. If you tap/press the button you'll cycle through the next speed and then off. I only use the first speed to make my protein shake and matcha. I feel like the high speed would just whip everything to pure foam! I'm hoping this lasts me a long time.

Quiet and Effective frother/mixer and Terrific Customer Service
Zulay Kitchen Powerful Milk Frother Wand We ordered two Zulay frother wands and after just several months of continuous usage one of the units stopped working and the other one was sporadically working, where sometimes it would run “full power” and at other times it was barely spinning or turning the beverage. I called Zulay and gave them my Amazon order number. After the Customer Service rep walked me through some minor things to check on the units she was also convinced that the units were probably defective. She had a replacement sent from Zulay along with a mini as a bonus for our troubles! And she had Amazon ship the other replacement unit. Both shipments arrived promptly within days and we have been using them for months now without any major issues. We use the units (the two “standard” wands) almost every day and they get used two to three times a day. They only take ten to twenty seconds to mix up cocoa powder, hot or cold. And the same goes for different protein powder shakes. What I especially like about these units is that there have been many times when I have had to use them off-hours, like between 5:00 and 6:00 AM. They are Whisper quiet so nobody gets disturbed. One generally can’t do this level of quiet stirring/mixing with a kitchen hand blender/mixer or shake blenders. These Zulay mixing units have really come in “handy” for us. We are very Grateful to Amazon for their prompt delivery, and especially to the Customer Service representative at Zulay for her help, and to Zulay for standing behind their products and providing us with terrific and prompt Customer Service! Thank you! Cheers! November 3, 2025

Powerful and silent!
Color: Lux Metallic Blue, Size: Rechargeable Z1 Motor Max
Wow, call me impressed! I just got the rechargeable version in blue and it's gorgeous! The metal shaft is thick, high quality and long enough to reach the bottom of a tall mug. And the double whip end works like magic. I had a cheaper frother (another brand) and this one blows it away! I couldn't even get much of a froth with my other one and having to hold the button the whole time was annoying. One press of this button and my milk was frothed in seconds. I didn't even use the higher setting! My morning latte is very happy.
