Maxx Power Ford Chrysler Style Tri Flow Aluminum Radiator 28 Inch

Description

Maxx Power Tri Flow Radiators are designed to eliminate your overheating issues. Temperature reductions of up to 24 degrees F over your current temp are not uncommon. Independent lab tests with LS motors have shown 20 degrees F drop in temp over conventional aluminum radiators and even more over OE copper/brass.

  • Designed to eliminate overheating issues
  • Temperature reductions of up to 24 degrees F
  • Fully TIG welded 6061 aluminum tanks and core
  • Unique design passes coolant though core 2x more than other radiators

It was developed with 2 rows and a 1 inch oval tube core and a unique coolant path that routes the coolant through the radiator core 3 times and increases turbulent flow while passing the coolant in front of the fan 3 times. Traditional radiators only pass the coolant 1 time in the front of the fan. This is what makes this Radiator the best on the market.

Fully TIG welded 6061 aluminum tanks, with 2 inch mounting tabs on each side make mounting in your car or truck easy, no matter what it is. Configured for universal fit with 1.5 inch inlet and 1.75 inch outlet, a machined radiator cap opening and overflow nipple on passenger side, plus a welded 1/4 NPT bung that can be used for a LS steam port or temperature sender up top, and another one for the petcock. Complete the cooling system with no fastener aluminum shroud (#20298) and 16 inch electric fan (#20243) specifically sized for MaxxPower radiators.

Specifications

  • Configured with proper inlet and outlet for Mopar and Ford motors
  • Radiator holds 1.45 gallons of coolant
  • 1 1/2 inch inlet on passenger side, 1 3/4 outlet on driver side
  • 28in wide x 19in high x 2in thick
  • Universal 2 inch mounting tabs on both sides
  • Machined radiator cap fitting on passenger side with overflow nipple
  • 1/4 NPT bung for LS steam port/temp sender fitting on passenger side
  • 1/4 NPT bung for petcock drain on driver side

Warranty

365 days warranty.

Customer Reviews

Rated 4 out of 5 by from Good built radiator This radiator is a great quality product. The only reason why I gave it four stars instead of five is because there’s not enough of an aluminum lip on the top and bottom parts of where the radiator fins are to mount a fan shroud and electric fans.

Rated 4 out of 5 by from Max Power Tri Flow Works with Install Skills Radiator works very well, but you must engineer a lower hose application to connect with the water pump. Fabrication of the installation mounting was not too complicated, but installing an electric fan other than the one Eastman sells can also require considerable engineering and fabrication.

Rated 4 out of 5 by from laking installation instructions Just installed the rad and transmission cooler. Had to go online to find instructions. Mounting studs for the cooler not strong enough, I broke two. Emailed Eastwood... never got a reply. The female connector for the fan, cannot get a match male connector to plug in. That male connector should be a pig tail included in the installation kit.

Rated 4 out of 5 by from Really nice I bought this radiator to put in my 57 plymouth running a 5.7 Hemi. I am in the start up stages so it has no miles to speak about but it was an easy install. The only problem I have is the angle of the bottom hose outlet . It would have been a perfect fit if that outlet were straight and not on an angle..Not a big deal to cut and rotate. The radiator looks to be well built.

Rated 4 out of 5 by from It looks good. I am going to have to make some changes to the radiator to get it to fit my car.
Date published: 2015-05-19
Rated 3 out of 5 by from Its an unknown as to the way it works. I purchased the radiator based on the online claims. It looks to be of high quality but isn't an exact fit for my 73 Camaro. I had to remove the stock core support and create a tray to hold the radiator low enough to clear the cap. Cap location is not great because it is over an inch higher than the radiator standing straight up. My champion radiator was a much better design. We will see if it works as advertised but I'm waiting for the delivery of my transmission and cooler si I can modify the lines since this radiator doesn't have an integrated trans cooler

Rated 3 out of 5 by from No difference! Replaced 22” Griffin Aluminum cross flow with this triple pass 22” , no difference in cooling. Sorry

Rated 3 out of 5 by from Pontiac GTO Have been having trouble with overheating on a GTO with overbored 455. Building another with an overbored 400 , so to eliminate a potential problem I got this radiator. The universal install flanges are facing the wrong way for my needs, so I had to cut the off completely. If the radiator had a "bridge" between the tanks especially on the bottom life would have been simple and could be installed using stock lower brackets. Called Eastwood and was advised not to install on core flanges as they would be damaged and cause damage to the radiator. Having to relocate brackets further out from original position and modifying them to fit the support where they'll hold the tanks. Also having to make top brackets. This more than I anticipated having to do with an "easy installation" product. Hoping I have the same good luck and and satisfaction as others when I get things running.

Rated 3 out of 5 by from Kind of helped I put mine in a '62 chevy c10 with a with a stock 327. I also used the electric fan and shroud recomender by Eastwood, as well as the coolant. My summer temps dropped from 220 to about 195. Better, but not the 180 Eastwood's video claimed. My brother also bought one for his F100, which has a 428 cobra. He was running 235 and dropped to 220. Not very significant and is running 2 pull fans and one push fan. Overall, it is an improvement, but not what we had hoped for.
Date published: 2015-09-06
Rated 3 out of 5 by from Temperature drop is only half the story How much the temperature drops in the radiator is only half the story on cooling efficiency. If tri-flow is so great, why not put the water back and forth 10 times instead of 3? Because it would be 10x more restrictive that's why. It's possible that this radiator might be better than some others, but I don't see the tri-flow as a real feature since it's 3x more restrictive than a regular aluminum radiator. Compared to a regular aluminum radiator this radiator probably cools 3x more, but with only 1/3rd the amount of flow (depending on your water pump) it doesn't matter.
Date published: 2015-06-25
Rated 2 out of 5 by from Not easy Bought the radiator to try and lower the running temp in my 55 Chevy. It was not tall enough to have the filler above the radiator frame. It would have taken to much fabrication to make it bolted up to the car. Not worth the effort. Wouldn't look very good either for a show car. Needs to be at least 4 inches taller to reach the lower hose and have the cap up high enough so it can be easily reached. Not really workable for the 55 Chevy. I returned it.

Rated 1 out of 5 by from Rad looks good On a 57 chevy nomad with B&M supercharger. I had a 3 core aluminum rad which the temp ranged from 190 to hot day trafficof 210. After installing the new rad system with shroud and fan the temp went from 220 to city driving of 280 and boil over. I was not happy with the results and all the extra work involved. I went back to my old system where I do not have to phone for a tow truck.

Rated 1 out of 5 by from hose problem... the lower outlet size of this radiator is 1 3/4''......it's the same size as the end that hooks up to the water pump. They DON'T make a lower radiator hose with 1/3/4'' at both ends. I spoke with a rep at Eastwood and he told me to be creative and make an adapter. hahaha , I understand the radiator will need some modification to fit in your vehicle but making the outlet end of the radiator 1 3/4'' is plain goofy. The lower end outlet of the radiator should be 1 1/2'' ....that is the stock dimension of most Ford, Chevy and Chrysler on their radiators. I'm off to the muffler shop to ask the guy to stretch the heck out of my new hoses to fit this odd ball radiator.....same story with the inlet at the top of this sub standard radiator. Good luck.

Rated 1 out of 5 by from Defective Radiator was defective. mounting bracket was welded on so crooked not sure how it even got out of the factory unnoticed. Picked up right away no issues there. Had to call over a week later when I heard nothing back only to find out it was on back order until 5/28. no email, no phone call.

Blown 351 Cleveland in an early mustang with a 4 speed, its always overheated. I used a griffin radiator 20 years ago, couldn't get a 4 core. Belt off the motor runs fine 150-160, belt on 200 plus. Will your rad make the difference over the griffin?

Asked by: Hotrods512
These 2 core, 3 pass radiators work to cool vehicles up to 500 hp or less. On average it will give you about a 24 degree temperature reduction.

Asked by: Abdu
Our Tri Flow Radiator is not a direct replacement for your Jeep. If your Jeep has a automatic transmission, then you will need to purchase the external cooler for the Transmission. You will also have to have some mounting bolts and a drill... Check this video out. https://www.youtube.com/watch?v=kJIR5-Sibvg https://www.youtube.com/watch?v=2lXvb7I_YHo

Will these work with an ls based motor? Isn't the outlet on an ls the lower hose and the inlet the upper hose?

Passenger side upper inlet from the thermostat and a driver side outlet. The stock hoses may not be long enough so you may have to swap out to longer hoses.

You only provide half of the heat rejection equation - temperature change. What about coolant flow? The triple pass flow has to add a significant amount of pressure drop. If you double the temp delta, but cut flow in half, you don't gain any cooling.

Asked by: Engineer
In an automotive cooling system the water pump and thermostat will determine coolant flow rate, not the Radiator. With our Triflow radiator the coolant flow rate will remain the same but the coolant will have the opportunity to spend more time flowing through the radiator.

These Radiators are not a direct factory replacement. You will need to measure the rad. support opening and then check on our web site to get the correct one you will need. The important measurement is to have the core of the radiator exposed to the opening in the rad. support.

When your sitting in your car, and the inlet at the top is on the passenger side, this is where the coolant is coming out of the engine, and the bottom of the engine coolant going into the bottom of the Radiator is on the driver's side. then the #20274 is what you will need.
