Answer 1

check your fan motor then water pump if negative check oil 4 water if yes you have cracked head or block

Answer 2

you could be low in coolant due to a leak, or the radiator may have some cold spots, which means blockage, or the thermostat could be stuck closed, due to coolant temp sensor or sending unit faulty, or the heater core could be stopped up. first check to see that coolant is full, then crank car and look at temp guage and when it gets to 200-225, see if the cooling fan is coming on.. also feel the hose coming off the engine going to the bottom part of the radiator is hot, also check the hose going into the firewall to heater core--inlet hose should be hot and outlet hose a little cooler, have someone check radiator with infrared thermometer for cold spot.. If the coolant is not flowing, then you will not have adequate heat..

First: did you replace the right recomended thermonstat for your specific region, also did you install it correctly with a coil pointed toward the engine not to the radiator? since you lived in Minnesota, a hotter thermonstat is recommended ( not 220F or 275 degF, because this is when it starts to open, you want a lower temp~ 180 degF-195 degF ). Second, since it was overheated, did you checked for enough coolant has been added ( leave your engine running with radiator cap open, at a certain temperature, thermonstat will open and drawn in water then shut off your engine and add more water ). Third, 40 % antifreeze with 60% water ( it boils at 100 degF). Last, check your temperature connecting cable, it could came off; broke or froze up? Last of all, if all the above suggestions have been inspected and all good, last thing you want to replace is your heater evaporator, it could gone bad since you uses it extensively in cold region.

Answer 4

I'm not saying you did, but are you sure you didn't put the thermostat in up side down,it's easy to make that mistake.
If that is OK make sure you got all the air out,start your engine and Waite for it to get hot enough to open the thermostat you will see the antifreeze go down then fill it up before you put the cap back on.

Answer 5

Cat woman is the nearest to easily right. in case you've an air lock interior the cooling gadget if the leak became mounted and that is refilled. one concern you may attempt this can artwork is, run it or force it lengthy adequate to warmth it up and get the water to flow and park on an uphill grade. That seems stupid yet air bubbles will bypass uphill and could artwork their way "up" to the radiator and get away. be confident and run the heater huge open even as waiting. save a watch on the temp gauge. in case you want to operate coolant, upload slowly to allow the air to flee. in case you force for 1/2-hour or enable it run even as sitting uphill for quarter-hour or so, and it nonetheless does no longer artwork, there is likely something else incorrect. If the thermostat is stuck open, the coolant isn't heating up adequate. when you're low on coolant, that is not in a position to flow by ability of the heater center and for this reason the heater isn't heating.

Answer 6

Check to see if the thermostat is in upside down, also check your coolant level, it must be to the top of the radiator.
