Hi I've got a 1996 c1500 with 5.7 Vortec and about a month ago the thermostat got stuck closed and it was overheating and then I replaced the thermostat with a stock 195° Thermostat and now my motor will warm up to the 195-200 then the thermostat will open then it stays at around 155° and no matter what I do I can not get the motor close to operating temp. the weird part is before the original thermostat got stuck I had no problem staying at operating temp. I have rebled the coolant multiple times replaced the thermostat twice and still nothing. it is colder where I am around 30-55F but it's odd even trying to rev the motor higher I still can't get it warm and tips or help is appreciated. Thank You
