Question about 2003 Chevrolet Blazer
Changed thermostat three times this month, changed radiator, vehicle has 13 psi coolant pressure. changed for dex cool to regular anti freeze. hottest temp is about 155. heater core lines with in 10 degrees of each other
I agree with mosthated357's post but i still would like to see that outlet temp at the t-stat/radiator in/heater core in closer to 190 degree F! This is a long shot here seeing how you changed the t-stat out 3 times already but have to ask ;are the t-stats rated at the correct opening temp?,are they the same brand and/or batch and/or standard/premium style, it was not so long ago I changed out a wheel bearing for an ABS issue 3 times in a month because of a defective batch from 2 diferent parts supliers! Turns out same company made them for both. Go figure! Bear with me here as here's another long shot in the dark but, Is the radiator fan clutch locking up to soon and over cooling the system?! good luck!

The chevy blazers are known fior heater core issues clogged going bad etc... The reason im saying this is because the only reason i could see you having a problem with the temp not getting hot enough is because then your heat in your car isnt getting hot or its taking super long to get luke warm, is that correct? If so 9 times out of 10 its a bad heater core...

3.7L & 4.7L Engines WARNING Do not loosen radiator drain **** with system hot and pressurized. Serious burns from coolant can occur.
NOTE Do not waste reusable coolant. If solution is clean, drain coolant into a clean container for reuse. If thermostat is being replaced, be sure that replacement is specified thermostat for vehicle model and engine type.
