Flowkooler high flow pump 1779 for the Cadillac 425, 472 and 500ci blocks. It has a CNC machined billet impeller designed with an increased vane count and a reduced impeller clearance to achieve greater flow rates, higher block pressure. A Type II Class II military grade anodize surface coating protects against corrosive fluids.

We developed this hi flow pump because Cadillacs are big and heavy and tend to get hot as they age.  It has been proven time and time again that reducing the cycle time between the heat source and the heat sink drops engine temperatures for slow speed cruising and stop and go traffic.

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

Asurion coverage was worth every penny!
Bought a window AC in 2020 and was offered Asurion coverage at checkout. Paid $39 for the 4 year plan and never expceted it would be worth the money paid. Honestly, never expected to even use it. That said...the AC failed about 2 years later so I made a claim online. The claim went in but required a call to an Asurion rep (very nice guy on the phone). He asked a few questions then told me the claim was approved. Total time to for the entire process was about 15 mins. I had the choice of having it repaired or a refund check. I asked for the refund. An emailed pre-paid UPS label was recieved a few minites later and the guy said they'd mail me a check when the UPS package was received, so I dropped it off at UPS. Three weeks later I had a check in my hand for $399 (the excact cost I paid for the AC unit 2 years before minus taxes paid). Really easy process and quick time to receive the check. The only thing to note is that if you make a purchase like that (large electronic or home appliance)...keep that box and packaging. Luckily I had it all and just popped it back into the box for shipment. Not sure how I would have dealt with that if I hadn't saved the box. Thank you Asurion, for delivering on your promise of quick and easy extended warranty payment. I'll defintely purchase the plan again with my replacement AC!

Clean air
I bought it to clean the air in the house took a few days to get it linked to my phone but finally got it working. It’s a little complicated because I didn’t know how to set it but getting better at it. I think it’s a good product.
