The Evans Prowler aluminum radiator has twice the capacity of the stock Prowler radiator. Steve said they estimate the total cooling system capacity is increased by 50%. The Evans Prowler radiator includes two (2) 1" aluminum fins replacing the two 1/2" copper fins in the stock (not sure what the stock is made of - I know it is not aluminum).... Evans contracts some of the mfg. work out for some of their radiator designs. However, the Prowler radiator is built by Evans and stocked at their PA facility. If you have any questions, I suggest giving Evans a call.

Here's a comparison of 1/2' fins next to 1" fins. Again, these fins are made of aluminum versus the steel or copper in the stock Prowler radiator.

Here's a picture of another Evans radiator similar to the Evans Prowler radiator...

They have an agreement with Dean from Prowler Pro to handle their radiators and you can also order them directly from Evans Cooling at 888-990-COOL (2665). Steve told me Dean was currently installing one in a Paxton supercharged Prowler and one in a stock Prowler. Steve said there Evan's suggested retail price was around $790 ?? (Steve said it's about $100 more than stock Prowler radiator).

In addition to the Prowler, they were working a external thermostat solution for the LS1 Corvette motor. The LS1 has a similar setup to the Prowler motor (99 & up) where the thermostat is on the intake side. Steve said this setup requires a thermostat 15 degrees lower than one on the output side of a thermostat to achieve the same normal operating temperature. They're leaning toward a German external mechanical thermostat for the LS1... And, I saw a new water pump for the new Hi HP Cobra mustangs where they've developed a new impeller with more fins...

Here's more pics from my visit.

Here's the LS1 Corvette motor on the Flow tester...

Engine Dyno in their shop...

One other bit of information I learned was that if you use their NPG+ product you must remove all the water from the cooling system. Just removing the radiator hose will not get all the water from the block. You may have to remove a couple of drain plugs on the block. Another product they sell can be used to ensure you have properly prepped the system. You add this liquid to a drained radiator and running the car for 15 minutes and than redraining the system.

Any questions should be directed to Evans Cooling... I want to thank Steve Pressley for taking the time and giving me a tour around the shop.

My radiator is a 4 row, serpintine radiator with dimpled tubes. That is the water flows like "S" through the radiator so it will go accross the fan 3 times.

Even though I spent all kinds of money to modify my front end my heating issue did not completly go away. With tony's panels the temps have been better.

With the other coolants you would be correct, but this time you are misinformed because of the different way Evans coolant works.

To get the technical answer as to how this works you have to call Steve at Evans cooling but Evans cooling said I could take out the thermostat without any problems because of the way their coolant works and they are correct. Today the car was up to temp in less then 3 miles, and always runs in the same temp range in the heat of summer or the cold of Texas winter (right in the middle) If you drive the car in Minnesota winters you would have to put in a thermostat, but I live in Texas.

Tell me what problem I should be having so I can look for it. But this systems works for me and is much better then overheating on a regular basis.

(as stated above) I have the Evans Radiator and fluid in my 99 prowler for over 6 months now with no thermostat and all my over heating problems are gone!!! 100+ Texas heat, A/C on max, Pulling a trailer with 20" wheels, 70 MPH, with a Metal Crafter front grill that only lets in about 2/3 the air of a normal grill, and no problems with over heating. Now that it is cold in Texas (below 40) the car warms up no problem. The People at Evens are the best.

I have read the posts about bleeding the system, but it did not fix my problem. Only 15,000 miles on the Kat now, and I drive it most every day. Turning on the heater to cool the car down is not the way to go.
