How to make a 24 inch Radiator fit in a Classic Mustang

[@kennethabrazee3540]

You cannot get this kind of information from your average garage. Andy you show real world problems with real world solutions. Thank you

[@AndyKruseChannel]

I appreciate that. Now I don’t want to let you down. 😁

[@Mustangshow67]

Good work, Not that much work on my 67 to do this but it is great with a shroud, I installed a 24" radiator and I run a 14" and a 12"fans off a Flexalite probe setup. Even with AC in Texas I have no problems for 12 years now.

[@AndyKruseChannel]

AC, no that's something I'd like to add. :)

[@SmackeysGarage]

Nice mod. The 24" radiator is a great upgrade for these older cars especially if you are going for a larger or more high performance engine.

[@AndyKruseChannel]

Thanks brotha!

Glad to see a guard on a cutting wheel - so many NUMBNUTS risk 'life & limb' using a cutting wheel without a guard. CHEERS from AUSTRALIA.

[@AndyKruseChannel]

Thanks 👍

[@heathhenderson7217]

Lots of discussion on this topic, handful of pics shared but your the first to show a step by step process. Thank you sir

[@AndyKruseChannel]

Awesome, thanks for the support! :)

[@TehShawns]

I used a very similar setup on my 68 but I just threaded bolts through the radiator mounts and welded them to the core support instead. Figured it'd make it one less tool/thing to keep track of if I removed in the future. Cooling setup has no problem keeping a small block at bay. Really happy with it.

[@AndyKruseChannel]

I thought about the bolt thing, but my fan shroud is a pinch too small for that to work. 😀

[@patwelter5092]

When I cut my core support open for a larger radiator, I used a 22" Mopar radiator. Inlet/outlet are staggered, so that worked out great. The fan from a Ford Taurus fit the radiator core perfectly. Cools great, and the fan works flawlessly. Looks like your setup will work quite nicely. Perhaps you could fab up "Z brackets to attach to the body of the fan rather than the sides. Great job.

[@AndyKruseChannel]

Great tip!

[@cesarramos7918]

Which radiator did you buy? My mustang needs this exact set up.

[@MrJoea11]

Making it look easy. 😊

[@AndyKruseChannel]

Nah, it's just the fancy editing I did. :)

[@LeeFred78]

Running an aftermarket stock sized radiator to keep a built 331 cool here in Arizona. Stock type water pump, thermal clutch fan, and a factory shroud keeps everything flowing.

[@AndyKruseChannel]

That’s good to know. 😃

[@jasonmartin3587]

Wow. You’re up to 7k subs! Great info, as always.

[@AndyKruseChannel]

Thanks! It's great that more people are finding the channel, I just hope they can find the same value that a lot of you early followers have found. :)

[@raptorjesus99]

Great video! I did this. You should toss the regulator. You need to upgrade that alternator for the dual fans.

[@AndyKruseChannel]

Alternator already upgraded, there’s a video on that if you’re interested.

[@rogjackson]

I agree with waiting for the final mount details to be ironed out after engine installation. Other adjustments may be necessary anyway. Sweet looking aluminum radiator though. Nice work Andy!

[@AndyKruseChannel]

Thanks! Hopefully everything goes to plan when I put the motor in. 😁

[@mikebroszczak5767]

Nice upgrade

[@AndyKruseChannel]

Thanks!

[@tfalcon1428]

I have the same radiator MCC 338 in a 1964 falcon & 1965 mustang what I did for the mustang was buy another radiator core support cut in 1/2 Move the parts right and left to make a bigger opening where it looks factory but just a bigger opening . Can bolt in also as well as weld in

[@tfalcon1428]

After you can bolt radiator like normal

[@AndyKruseChannel]

Hmmm, seems like more work. :)

[@tfalcon1428]

Wish I could send a picture , it is work but better in the end just saying

[@leovargas3013]

The 68-69 Ford Torino has an option for a wider radiator, it uses mounts that attach at the top and bottom with rubber cushions and steel brackets. Could be an option. All parts available from AutoKrafters and Mac auto parts.

[@AndyKruseChannel]

Good to know. :)

[@Menace510]

Nice Andy! This is the next upgrade I’m actually getting ready to do as well on my 1965 Mustang! Except I’m putting a crossflow style radiator in. Im going to have to chop the whole top of the support out and and build probably a housing and lean it towards the front of the car for clearance issues with the motor. Did you ever do a follow up video on this?

[@AndyKruseChannel]

Sounds good, I hope everything works out for you. :) I did not do a specific follow up video, but everything has been great. I took the car out on one of the hottest days here and the temp never got above 195 while sitting at a light, so that's a win.

[@stevenl378]

Very helpful thank you answered questions I didn't know I need to ask yet Haha 👍👍👍

[@AndyKruseChannel]

Happy to help!

[@wolfthornhawkridge5705]

Radiator cap will clear, however, if you got the Champion radiator do not use the radiator cap cover they send with it. It sits up just high enough with the cap cover on a 65-6 to make the hood not close good. Also, your system should run 10 to 15 degrees cooler.

[@AndyKruseChannel]

Cool. This Rad did not come with the cap you are describing, but I did get one for my last car.

[@tfalcon1428]

Mine works great with no problem

[@mdean73022]

FYI I installed a Ron Davis radiator it is 26" wide. Alot of work but seems to work.

[@AndyKruseChannel]

Yeah, there's a lot of good radiators out there, one for everyone's build. :)

[@Titan-uy1qy]

Awesome!

[@AndyKruseChannel]

Thank you! Cheers!

[@ILoveToMTB]

Great video. Thanks for the info. Can you say how thick the radiator is & how thick the fan is? I'm wondering about clearance issues in my application.

[@AndyKruseChannel]

The thickest point is about 5-3/8" (about 4-3/4" where the fan motor is not in the way), but that's where the fan motor is. Since there are two fans, they're offset from the middle, so something like the water pump pulley has more clearance since the fan motors are not at that location like where there's a single fan (like what I had before). Also, please note that I cut some of the core support out, so the radiator sits a farther from the engine, making more room than before. :)

[@hemlock911]

Great info and video! I have been planning a larger radiator swap. Did the upper and lower radiator hoses work or were others needed?

[@AndyKruseChannel]

The stock hoses for my '66 fit. The inlet and outlet of the radiator is essentially in the same location (relative to the engine) despite the radiator being wider. This allows the use of the stock hoses to be used. :)

[@elbronco5532]

Great videos andy any results reviews where it runs with mod set up,?

[@AndyKruseChannel]

Sorry Boss, I'm not understanding the question.

[@3wbasie]

Hi Andy I have a really similar engine build to yours and I'm having some over heating issues with an a 3 core aluminum radiator that is the stock width. I have two electric fans with a shroud and when I'm moving the engine runs around 178 but as soon as I get caught in traffic the temp creeps up. I am looking into doing what you have done in this video but I am concerned that it will run too cold when I am rolling down the highway. So, I am curious as to what temp you run while your moving.

[@3wbasie]

Also, when you dropped your engine in did you have any clearance issues with the electric fans?

[@AndyKruseChannel]

Temps on the highway, are around 180. I have not seen the temps get above 195, even on the hottest days of this summer. I am running a 180 degree thermostat. You engine will not run any colder than the thermostat you are using because it won't open until it seems the temp you have chosen. No issues with clearance, plenty of room between the water pump pulley and the electric fans. :)

[@chrisdavis4545]

What amp relay did you use? What awg wire did you use? I'm reading answers all over the place on a Google search. My engine compartment is getting cluttered with relays so i was looking at relay boxes on Amazon and most come with 40amp relays and 12 awg wire if you get the pre wired ones.

[@AndyKruseChannel]

40A relays and 12AWG wire is sufficient for your application. However, you should also put fuses inline for your fan(s) as they can be very power hungry and it's easier to replace a fuse instead of melted wiring or a blown relay. :)

[@BigFish6161]

Now that you've had the 24" radiator for a few months, what do you think of upgrade? has it been helpful?

[@AndyKruseChannel]

Yes, the 24" Rad and dual electric fan combo brings the temps down fast. I haven't had it through a Summer yet, so we'll see this year how she does. :)

[@pauls7751]

Did you have this in mind when you moved the battery to the e trunk?

[@AndyKruseChannel]

Yes. (where's the evil smile emoji?) :)

Absolutely. Was just driving yesterday where it was 90 degrees out and I did not see the temp go about 185. It was glorious. :)
