We are temporarily ceasing the restoration service due to intermittent labor issues.

Restoring Pumps with a FlowKooler Hi Flow ImpellerPLEASE READ PRICING INFORMATION AT THE BOTTOM BEFORE ORDERING and NEVER SHIP US ANYTHING WITHOUT YOUR CONTACT AND PUMP INFORMATION ENTERED IN OUR SYSTEM IN ADVANCE. KNOW THAT THE PROCESS CAN TAKE 3-4 WEEKS.
If you are interested in a rebuild you are probably (A) restoring a numbers-matching car or (B) cannot find a new pump anywhere and either want a conventional pump or have experienced the benefits of hi flow. We have been helping restorers for 40 years in the construction of our radiators so it was an easy decision to use our hi flow impellers designs for numbers-matching cars and unavailable castings.
There are 3 scenarios we commonly see:
A. The casting volute, diameter, depth, angle and rotational direction match an existing pump impeller
B. The casting volute, diameter, depth, angle and rotational direction is close to an existing pump impeller but requires some modification
C. Nothing matches an existing impeller and we have to design from scratchWhat’s the process?
Step 1: Notify us that you have a pump and what it 'fits" in the order notes section of the check out process.Step 2: Send us the pump and the timing chain cover if it is available.FlowKooler500 Linne Road - Unit IPaso Robles, CA 93446
Step 3: We’ll receive the pump and inspect the casting and impeller.
Step 4: We call you with information and a ballpark estimate of the cost to create a hi flow impeller for your pump. At this point, you move on to the next step or we just return your pump to you.
Step 5: If we proceed with a re-build, we'll ship your pump to a specialist that dismantles, cleans and installs new bearings and seals.
We use this company because they're experienced with dismantling fragile castings and can source, create or modify bearings on site that may take us weeks to source. They are fair, honest and have a quick turn-around. If they find a cracked casting they can sometimes repair it for an added cost.
Step 6: The pump is returned to us and we install or modify or design a bespoke impeller and then install the impeller. The process can take 3-4 weeks.
What’s the cost?
Obviously it ranges but the costs for the first scenario described have been tracking $299. Modifying can be ~$60-350 more. Designing a one-off bespoke impeller costs a far more. After digitizing the volute, drawing the model, procuring vice jaws, programming CNCs, and setting to machining a batch of one unit the cost can approach $700-$1,000. Group buys and clubs can help divide the development costs.
The price you pay when ordering on our website may be the final price or a deposit toward the final price. We do not know until we see what you provide us and we assess what is involved. You can email us with the details of your build for more information.
We do not undertake any work on your behalf without your consent and your exposure is always limited to the cost of the freight.
What if I think a high flow pump costs too much?
If the costs are too much for your wallet to bear we can simple rebuild your pump with new bearings and seals and reinstall the original impeller. This is not a hi flow solution but the costs range $180-$200.
Isn't there a way to get the cost down?
Absolutely - volume. The more people that need the same application, the more we can divide out the costs of design, drawing, programming, set-up, materials and machining time.
Will you design for our club?
We can work with clubs and specialty catalogs and, if we hear a common request, we’ll keep the customer names and when we get to reasonable “batch”. If the design costs can be spread and the cost is reasonable, then we’ll contact all interested parties and they can buy together. If we perceive there is a market, we'll even subsidize the development costs of the impeller.
Can't you sell me a kit? We do not sell a kit.
Here is a short list of some of the past restorations, rebuilds and retrofit pumps. This is not the complete list; we add to it when we have time.
