I took my truck for a test drive today after the oilpan,valve adjust, vac adv replacements and it overheats. went to 210 in about 5 min on the road. came home and checked the radiater , full no leakes. I pulled the thermo housing and no thermo , went to napa got a 180 and replaced it. filled tank to about a half in above the cores. around the block still 210. checked timing ,on the dot with no vac. the centrifical moves when i rev . vac works when reconnected. i had put in ac r45 plugs with the valve adj . replacing r43. it ran around 180 before i started to "fix" it any ideas where to start?
