    If I'm in the wrong spot sorry I'll move it to the right area if someone lets me know
    Any, what is everyone running for radiators? Just the rockauto/aftermarket ones? Is there a better performing one that fits?

    First, there are two different versions of radiators for our cars.
    The 26” wide version (used on FMJ's with A/C, trailer towing, police or taxi) and the narrow version (which can be 18”, 19”, 20”, 21” or 22” wide, depending on the year) on FMJ's that don’t fit the above description.

    My ’77 Volare wagon 318 (no A/C) has an 18” wide radiator.

    All the factory FMJ radiators are made of brass. Brass is not as good of a conductor of heat as copper or aluminum. Copper is too soft a metal for radiators, so not used. If you don’t have other issues (ie: blown head gasket, rust/crud in cooling system, stuck thermostat, etc.) the brass unit works fine.

    I might have purchased the very last all-brass (Modine) 26” radiator for my ’86 Fifth Ave, a few years back. The ones they have now for our cars are aluminum with plastic tanks. They work ok but look odd for our cars.

    This is an 26" plastic/aluminum radiator, which most likely came from China.

    I have an opinion that plastic has no place in an automotive cooling system because of warpage and melting, but the industry has gone that way. I’m surprised they are not making engine blocks out of plastic now days (OK, rant over).


    Personally, I recommend taking your original radiator to a radiator repair shop to get repaired.
    In most cases they can fix your existing radiator for less money than you can get a cheap Chinese unit for. Also, most the cheap Chinese radiators need some work to fit correctly and they have poor quality control (if they have such a thing as quality control …).


    Note: if you currently have a narrow radiator (ie: not the 26” wide version), it is a bit of work to upgrade to the 26” version. The two metal pates on both sides of the radiator core support are made differently between the wide and narrow versions. It takes a bit of cutting/welding to change the plates out.

    Another method is to bolt the wider radiator in using new holes (that you make).
    If you do this, you have the option of getting out a saw and cutting the core support plates for the increased air flow OR leave the wider radiator with the smaller air entrance hole (ie: not all radiator cores will get any airflow).

    This fellow forum member converted his narrow radiator brackets with no cutting (on the car). He made plates to fit the wider radiator - but he also has a few core tubes that don't get any (or much) airflow. The original plates are circled (below).

    If you already have the 26” wide radiator, then the above steps don’t apply.

    Hopefully this helps.

    You might want to make note of what vehicle you have (I found it, but it took a bit of digging.

    I then went to RockAuto.com and they only show two radiators in stock (both are 26"). Most Fifth Ave's come with A/C so I think you have a good chance of having the 26" version.
    The cheaper one has a picture looks brass but the “info button” says it is plastic/aluminum.

    (the picture will not be what you get).

    The more expensive version is also plastic/aluminum:

    The top/bottom tanks are plastic. The core (light colored part) is aluminum. The black side straps will either be metal or aluminum (painted). The bottom picture is made to fit many cars

    BudS sorry didn't even think to post for what car. 86 5th Ave with a.c.. ya I saw the one on rock and it just looks cheap. Glad to know about the size difference and what the measurement was for. Ill see if there are any places that do repairs/rebuilds but seems those are getting fewer and further between. I have had very mixed results with plastic tanks on cars that didn't come that way.

    My Aspen has a Be Cool brand aluminium cross flow radiator. It was installed by the previous owner for the silly crate engine he installed. It does work quite well, but it is not a direct replacement.
    Some checking on summit racing no longer shows that radiator listed for that application, but a universal fit one could be an option.
    Summit racing does list a direct fit aluminum radiator made by Griffin, which according to Griffin fits both Aspens and 5th avenues. It appears to be an all aluminum radiator. It is offered in two sizes. It is however rather expensive.

    I posted this in the other rad post, this 2 1 inch core direct bolt in all al, has worked great in a car with a 4:56 rear gear. $130 to me. I also us a crossflow in another car with the same great results at a far greater cost overall.

    I painted the top satin and the side and lightly misted the core.

    Most radiator shop don`t do the business they did some years ago. The recore cost twice as much as a new radiator sometimes.

    The first shop got back to me with a quote of $360 to recore the radiator.

    I think that's more or less what the radiator shop here (Glen-Ray Radiators) charges for a copper/brass recore now days. They built mine back in the '90's (26" F-body tanks/sides with a 3 row core). Back then it was $200 and they supplied the tanks and side brackets. Best part about them is, they are VERY Mopar friendly.:cool: Worst part is, the shop is in a part of the city that I don't feel real comfortable in anymore. Same location since the '40's, city changed around them unfortunately but I digress...............Only place I know of in the area who can bubble crimp R134a A/C lines and silver solder fittings also.
    All the other rad shops around here closed years and years ago because they couldn't justify the cost to comply with the ever increasing regulations, and doesn't that sound familiar.

    Bud, Im the only person thats been in my shop in over 7-8 years with the exception of a big spider or scorpion from time to time, wifes not allowed or desires to go there, so If I gently set things here or there I dont worry too much. Its rare I drive them and some say I use cotton balls to wash them, but really soft warm declawed kittens do a better job, not!.

    A500 I dont feel comfortable in the nearest town of 3000. I like my indoor cars, my wombat and like my 10 outdoor guard cats. Keeps the big owls away.

    hehe.

    I don’t think my wife has been inside of either of my garages in the twenty years we've lived there. My kids do, until I ask them to help with _ . . . and they vanish.

    I’ve got a 22 inch Champion Aluminum rad for an A Body in my 1979 Aspen RT, I forget the part number.

    Would anyone have the part number for the fan shroud?

    Sorry, a bit late to the topic, but the pic BudW posted was mine as I documented the re-do of the coupe and in particular the move to the wider rad given that the car was originally a /6 setup.

    Anyways, for what it is worth I actually went with the following setup:
    43-3959 Radiator, ReadyRad (Proliance), $129.99 USD

    Now that was a few years ago (yikes, my build spreadsheet says 2006...LOL), and the rad was purchased at the local AutoZone.

    As I went looking for the up-to-date info on that part I actually found the prior forum post on this very topic => slant 6 to v8

    Alright, looks like you have found something already, aluminum will xfer the heat faster, so should be a better performing rad.

    M_Body_Coupe: its amazing how quick it goes by. i still find it hard to believe that i've owned my shelby charger that long and that my oldest daughter wants it for her first car and that will only be another year. i need to get my 5th ave done so i can have the space to tear into it and rebuild it before she gets driving
