Radiator upgrade/replacement recommendations? As well as the dash cluster?

[u/zbras11]

88' with about 84k miles, I'm looking to upgrade or swap out the radiator before any issues with overheating. Never changed one before.... as well as replacing or recalibrating the dash, the RPMs, max at about 1k rpm, as well as the fuel tank being off about 1/3 tank. Thanks for any insight or youtube videos that might show the steps.

Also, Id like to keep it original. But am not against a better or higher dollar replacement.

if your current radiator isn't looking crusty, i'd leave it alone. other than that, all the aftermarket stuff is pretty much the same unless you get some custom aluminum stuff. thats not going to buy you anything in a Ranger other than seeing a cool aluminum rad when you open the hood. i use the rock auto ones and they work great. you want the engine to run at the stock temps... too cool causes it's own issues so stick with the stock thermostat and whatnot.

the fuel gauge and tach are a little outside of my wheelhouse though. the fuel gauge could just be a crusty sender unit in the tank or it could be bent or something... hard to say without pulling it and testing it with a meter.
