What should I change next.

This week, my old radiator decided to do its impersonation of the Bellagio Fountains in Las Vegas. I was able to go with the Mishimoto radiator and have noticed a real difference in the way it functions. I have 324,000 miles on the truck. Anybody got any suggestions on what I should replace next.

Thanks in advance.

The rig will let you know what's next. But if you want to spend money on to prevent issues, engine rebuild would be a good start, vacuum lines, might as well get a new wiring harness, new bearings for axles/hubs, all fluids change, might as well do a frame off and get the rust taken care of before thing falls apart, front end joints/bushing, springs/shocks, headlight/bulb all around, tires/alignment, brakes/pistons, exhaust might need redone if rusted, I am sure there's more but that just what comes to mind.

Not apples to apples but cooling systems can be a "weakest link" scenario.

A couple years ago on an '01 Ranger I noticed the rad cap would leak, just sitting in my shop, vehicle not running, on warm days as the ambient temp would climb.

Tested cap and it was bad of course. Replaced cap and then Ford's stupid 4.0 plastic thermostat housing sprung a leak. Replaced that and then radiator side tank began to leak LOL

The point: not a bad idea to pressure test your cooling system to see if anything is "NEXT"

If you're gonna do P.M or restoration work, focus on one system at a time until that whole system is 100%.

Did you put in a new thermostat? Was the cooling system flushed? Did you replace ALL the coolant lines? Not just the radiator hoses but the other misc. lines like the heater core, oil cooler and overflow bottle lines? Does the heater core need replacing? If the radiator let go because of age, that's probably not far behind it, even though it should last a little longer because it's not exposed to the elements.

I am religious about changing fluids. Transmission, front and differential, coolant. I need to change the brake fluid because I have been taught that brake fluid is hydroscopic, meaning is absorbs water. Truck was bullet-proofed 150,000 miles ago. New glow plugs, new starter and I had an injector go bad and while the engine was opened, I had them change all 4 injectors on the one side.
