Need to keep them rads clean.
Mine get cleaned with a Rad Genie after every field use but and I say but before I even set up to clean them, I take a 'spritz bottle with water and Dawn dish wash detergent in it and spray down the rad from the fan side and the front side, soaking the rad fins. Dawn has a desirable effect, it loosens any crud and allows the 'Geine' to flush it out much more easily.I never use water as it makes the dust turn to cement in the fins. I reverse blow out the fins with air EVERY time I mow and have never had a problem.
Be careful using Tide as it is alkaline in nature and can can cause corrosion with non compatible metals. Dawn dish wash liquid is much better.Something I do that works. Get a spray bottle. One of them garden sprayer one quart jobs with the finger trigger works great, with the adjustable tip. Fill it almost and then add a cup of powdered TIDE washing detergent, fill it on up. Use hot water. Spray on when everything is dry so that the dry soaks in the soapy liquid. Wet it down good. Let it set a little bit. Then hose it off. You can also use on a dry engine and not have to use a damaging pressure washer.
Also, inside the cooling system, you can use dishwasher detergent. It does not foam. You can put a cup in the coolant system and run it a week and see what all comes out. It'll flush your system.
