1999 Ford ranger overheat issue

(1999 Ford Ranger)
Changed everything on 199 Ford ranger as far as cooling goes . Runs fine on startup w/ AC on. Drive it down the road,runs fine,but the first time I slow just a little ,temp start to rise toward hot. The only way to get it to start running co heol is to accelerate up to 70 or 80 mph or shift to neutral and rev for about 10 seconds. No water leaks visible. Does I have air in my cooling system. If so is this causing my problem.
What seems to make the problem better or worse? When hot
How long have you had this problem? Few months

Well since “everything” related to the cooling system has been replaced - like the radiator - cooling fan clutch - water pump - thermostat - the engine passed a combustion leak test and this has been an ‘ongoing’ problem - it isn’t likely caused by air trapped in the cooling system..


Therefore It’s a mystery wrapped up in an enigma surrounded by a quagmire..

Good luck!
