RACE ON!!!
Whenever I see this posted I can't help but imagine a guy poking around under the front end of the car with a garden hose.

This will do nothing to clear the radiator, that's your a/c condensor there. The radiator is the one behind it with 4 plastic shopping bags and 22 bird feathers stuck on it. Shroud has to come off, it takes some elbow grease to clean the radiator.

Several years ago, I had an overheating problem. Talk about throwing parts at a problem, I did.

1. Changed thermostat (160)
2. Changed hoses (both)
3. Purchased a "big mouth air dam"
4. Flush coolant and replace with 50/50 mixture & burped system
5. Pulled and cleaned radiator
6. Changed to new radiator cap
and more.

Turned out I had a bad (stuck) thermostat.

Needed a new thermostat and hoses anyway. The rest was just trial and error. My bad.

Runs now at 170-174 highway and 190-199 in heavy traffic.

Yeah, I did it right last fall before it went away for the winter. It's had less than 500 miles put on it since then and it is visibly clean except for a few oak leaves that I removed.

That's all preventative maintenance. The bad tstat is just the excuse to get you started. I've done the same.
