I understood that 221 was just a spike...perhaps I should have said reaching 221F is not normal? that said, you need to find out what aspect of the cooling system isn't working properly, and you haven't ruled out air in the system until you do a pressure test. After that, install a 180F thermostat b/c even if the t-stat isn't the issue, this needs to be done anyway. There's other posts on how to check and see if your radiator is clogged by Savanahbuzz...something about taking temp readings at the top and bottom of the radiator, ensuring >10F difference. Checking the fan clutch is fairly easy if you have a basis for comparison. All these things are good preventative maintenance anyway, so you're not out the time/$ if it doesn't fix the issue.

Thanks for the offer. This texas heat can really kill a car! I'm hoping to change the tstat and see where I stand. Savannah buzz had said he uses a fan from a Chevy blazer. Anybody use it on a disco2?

And when off roading in the desert with ambient temps of 115 degrees my engine doesn't go above 200, And that's with the stock 190° thermostat
