always good to clean the throttle plate with carb cleaner spray after removing rubber duct intake hoses, The temp rise may be low coolant or air in system going around, or a slipping water pump at higher speeds from a loose belt

Would cracked/bad gaskets cause this? I was told there is coolant flowing into the packs/plugs due to gaskets needing to be replaced.
