I've had good results as well. I think I've used the FlowKooler pumps on 3 different cars, and nothing bad to report. It's too bad people don't speak up as often when everything is working OK, as much as happens when problems arise . I think that's just normal. Even so, there's no good way to know how pervasive an issue is with any one manufacturer..Luck of the draw I guess. Mine has been running fine for over a year now. It will be moving to my new engine soon.
Hey, no problems here. Granted it's not well seasoned but it's been probably 8 or 9 months with 4500 miles? Something like that.I've had good results as well.

Which Flowkooler part number are you looking at that is back ordered until April? If the two linked water pumps are indicative of your setup, 289-351w with the water outlet on the passenger side and standard rotation, why don’t you just get the Flowkooler 1681? The estimated ship date shows as tomorrow if you ordered it today or even up until about 6pm tomorrow night PST. I’ve had this same water pump on my 351w with 450hp for 7 years now and without any issues at all. Knock on wood. If this is the water pump you’re referring to, it’s also available and in stock from Mustangs Unlimited.This is my first post on this forum; so much information available just by searching that most of my technical questions have been answered.
While I can't add anything to the quality of the FlowKooler water pump discussion, the data point I do have is that I had ordered one early February knowing they were back ordered until February 22... I could wait a couple of weeks. February 23rd comes and I get a notification that they are now back ordered until April 12th. This leads me to believe things aren't running as smoothly as they should over at FlowKooler.
Anyhow, April 12th is too long for me to wait so I'll be moving on to something else (probably one of the below options).
1966 FORD MUSTANG GMB High-Performance Water Pumps 125-1420P
Edelbrock Victor Series High-Performance Street Mechanical Water Pumps 8841
The GMB has great reviews on Summit and the Edelbrock has great reviews on this thread. The price difference is significant at 4x for the Edelbrock.
I hope FlowKooler gets things straightened out as their product at ~$120 was filling a middle ground price option.

Heck no. Aluminum over cast iron any day of the week IMO. They're lighter and dissipate heat much more easily than the cast iron will. It's a similar analogy with aluminum vs cast iron cylinder heads. Plus the aluminum is in stock, ready to ship and it's even $2 cheaper :grin2::grin2::grin2:
Wouldn't your car run cooler with an aluminum high flow water pump? I'd have to think the aluminum would make it run cooler, especially a higher flowing one as compared to cast iron. And no doubt it's not going to be quicker with the aluminum. That being said... I'm all for shaving off weight, especially in the front end where it's not needed. A few pounds here and a few pounds there will add up over time, especially if moving the battery to the trunk, using an aluminum intake, carb, heads and other weight saving pieces. I know that some water pumps come with shims and whatnot, I guess I had success with my Flowkooler water pump and the original style timing cover.Not all aluminum water pumps are interchangeable with an original cast iron water pump. Depends on things like does your water pump have a backing plate, and what type of timing cover do you have. Nothing wrong with a cast iron water pump. All things being equal, Your car is not going run cooler with the aluminum pump, nor will you be quicker with all that weight savings
