Check the radiator fins. Sometimes they get plugged with dirt, dust, and mud. Wash the radiator from the opposite direction of the air flow.Not the same direction as airflow. Also Highlifter offers a bigger and better flow radiator.Sorry I didn't see this sooner. Us 3rd shifters can't see a computor screen that well, in the sun light.

Do you plow snow in low or high range? Should be low range only.

hey thanks for your input, i decided to ignore my dealers recommendation and pull the water pump apart the impeller was sheared off, no coolant flowing, so i ordered the parts today, one question i have is the water pump and oil pump are chain driven, but that chain seems super loose with no tensioner my dealer didn't even have a good view of this or any specs on chain tension, i dn't know if this had any thing to do with that or what? or if i should just replace it or what, thanks again.

Not sure about that question. Ronnies mail order has some pretty good pictures on it, In the oem replacement section . Also going to PM you about some other options.

Hey Buddy

Im new to hear, but found an old article of yours.

Did u have any luck with the loose oil pump chain?? I have an 03 model with an incredibly loose chain, sounds like it skips along while trying to start.

Can you please let me know how you went, or any info on whether I need to replace, or somehow tension??

Any info would be greatly appreciated.

Cheers
