Hey all, new to the forum but I picked up a 2003 700, was running good but then the t in the radiator hose shattered when the kid was running it, long story short it got to like 250 degrees (have a aftermarket temp gauge on it) well they pieced it back together and put water out of the cooler full of ice in it. I replaced the head gasket now it doesn’t blow anti freeze out of the overflow resivor but it still gets to like 250 degrees…. Doesn’t boil over until I open the rad cap just a little. Jacked up the front end to purge it to get the air out. Another thing I noticed is it now sounds like it’s shifting into a different gear when you accelerate with it. It’s not loosing antifreeze but is it possible the head.is cracked from the cold water? And it only acts up going down the road. Sitting idling it will climb to like 220 fan comes on and it drops to like 160 ish. I cleaned out the rad and made sure the thermostat was working properly. Just don’t understand it. Thanks for any and all help
