Truck Gets Hot

[Sparkplug]

I got my truck running. Runs pretty damn good, except it gets a lil hot sometimes. If im goin down the freeway at about 60, its fine, but if i go 70+ it gets to about 220 degrees. Normally its around 190, but if i get on it it will go to 210-225. Same with off roading, if i get on it for a while in 4lo it heats up. Its got a brand new radiator, fan clutch, 1 yr old thermostat, and aftermarket temp gauge. Im just wondering if this is normal for these engines, or if I should be looking for another problem. I know hg goin bad can sometimes cause overheating, but my oil looks good, and it runs tits. Thanks, input is appreciated.

Any time my temp gauge goes anywhere above "that right there" I know there is something wrong, but that is with the stock gauge.

Could have a blockage somewhere, also did you replace the hoses. If you have a weak hose it can and does collapse under load which will restrict flow. I'm guessing that you've replaced the cap since you did all that other work. If you have an air pocket it can cause that too. See if by turning on the heater when it gets that hot if it helps. That usually is the tell-tale sign of poor flow. You may want to see if it is the pump after a while the fins can corrode reducing flow.
