make sure there is no air in the coolant system. As a air lock could accure preventing coolant from circulating and over heating resulting.
look for a plug at the highest point in coolant system. if no plug is found remove thermostat and housing. pour 50/50 water/antifreeze mixture slowly into cold engine block till full. install plug or thermostat. remove radiator cap making sure coolant is full right up to radiator filler neck. also make sure coolant is up to the lower mark on radiator reservoir leaving radiator cap off run engine to operating temp. coolant is flowing threw system when upper rad. hose is hot. shut off engine let cool check and top up coolant levels while squeezing upper rad hose to expel any air that might still be in system. eplace rad cap. take for test drive making sure temp. stays in normal operating range recheck coolant.. as stated at the beging very important that all air is out of coolant system as a air lock could acure preventing coolant from circulating resulting in a over heating situation... hope this helped
