I have an 84 pickup with a 6 in lift and 33 boggers. It was running great with the 22r, I just changed the water pump and it was runnin around 185. Yesterday I was cruising an the temp slowly started to rise, I was practically home so I got it home and it was at 210. It was full of antifreeze/water. I have no idea why it's runnin like this. I changed the fan but still runs 210/230. At idle runs perfect 185 all day. Any help Is greatly appricated
