Steam coming from radiator

I always come here to read up on info about ranchers, but this is my first post. I have an 07 420 FM rancher. I went riding this weekend and my coolant temp light came on for the first time. I do wooded trail riding with some nice size mud holes throughout the trail. The temp light didn't come until after I had been riding for 4 hours (we stop here and there about every 20 minutes). I detailed everything yesterday, got it all cleaned up (and dried off) and after I drove down to my garage and parked (engine was at normal temp) I noticed steam coming off the radiator. I haven't pulled off the front plastics yet to verify, but I'm thinking I may have a cracked radiator. If that is the case; are long term fixes beside replacing the radiator all together?

Did your fan ever come on? Is it leaking coolant anywhere?

Yes, the fan kicked on as normal when I was riding and after I parked it in the garage after cleaning..............Good news though, I think I just jumped to conclusions. I went home and ran it last night till it was hot enough and the fan kicked on, but no steam at all this time. Probably just had water left in the radiator fins (even though I let it sit for a good 3 or 4 hours after washing) There was a good amount of steam coming off the radiator the night before, so that caused some alarm for me.

False alram, thanks though

Check your coolant level if you haven't already

Yeah, I will be checking the fuilds tonight, I didn't really feel like removing the radiator cap list night while it was still hot; but I'm almost a 100% certain they'll be good since I had a stealership do the full 40 hour break in service about a month ago...........After reading up on the other "over heating" threads, I'm going to get in there and detail my radiator because my fan seems to be running more than it was at the beginning of the summer.

Thank you for the quick responses
