Your belt is a 7480. top width is 7/16" which is most likely what your rig calls for. the alternator you got is aftermarket. it's also well known that the auto parts stores carry most things nowadays as a "one size fits all" on a lot of parts. I question if the alternator you got has...

what series belt (top width) are you running? some use the 70 series but the pulley on the new alternator might need a 90 series (old Napa part numbers top width sizes) for reference a Napa 7560 belt has a 7/16" top width and a 9560 has a 1/2" top width. both will fit around the same...

Check the belt wear if it's already tight. if the bottom of the belt is against the pulley then the belt V section is worn and needs to be replaced. not unless the pulley is not the right one and the V section is too wide made for a wider V belt. in that case you;ll need to swap the pulley...

Yeah, I didn't look at the overall size. we would need to measure ours to see which one fits best. I would assume the larger one. Honestly for core rows, I can see where the difference between 3 and 4 could be negligible on cooling performance, being more are stacked and more air flow would...

Welcome @Eugene Rider tell us a little about your rig. 69 model with a 6.5! we have to see some photos please :) what year is the engine and it's electronic system from? my first thought is if it has the DS4 IP and it still has the noise filter connected to the optic sensor on the IP, that...

Belt sounds like it's loose, that will end up busting and leaving you. hows your gauge reading?

The one I posted showed to be a 4 row core, but I didn't look at the hose bibs or fitting sizes.

Only drawback is the cores. this one is a 3 row core. I'm sure we can find one that has the 4 row core and the larger ports.

it's not a bad price for a copper /brass radiator. I looked at the application listing and it shows all of the big block engines, the pic looks like it has all the right hose bibs, even for the heater hose. I would reach out to Summit and get them to send you the specs on it for sizing and...

Yeah the older chevys used them and had cross flow radiators as well. my old El Camino used one just smaller. Looks like all of the auto parts now used the aluminum with plastic tanks as replacements. I did find this on Summit racing. this one will fit a 77 pickup with a 5.7 or 7.4l...

I was thinking about a copper radiator, but not sure if they make one for our rigs. maybe the same one that fits the square body rigs with a 454 or 6.2 diesel will work if they are still made in copper from normal suppliers

The condition of those batteries is most likely what took your alternator out. they will take your new shiny chrome one out too!

Since they are still new, you might try a battery desulfator to maybe rejuvenate them. it's basically shock therapy for the battery, but it's unlikely they will recover. with the test results showing under 400 cca left in them, I would not try and crank it with them at all. any electronics...

My first thought was since it's at the first few tubes, check the welding at the bracing that goes across between the tanks. wondering if that has also cracked allowing the core to flex. where it's fins are damaged, I know it's real easy to damage them where it looks worse than it really is...

I vote you have the best looking 6.5 under the hood there! I jeally LOL all that shiny stuff! Those nuts should hold and lock in place well, I was also thinking nord locks too but looks like you mastered that with those nuts.
