Question about Cars & Trucks
Car keeps running very hot, changed engine coolant sensor and upper thermostat
Unless the water pump is leaking that is not the problem. You may have a leaking engine cylinder head gaket have it checked by a local shop.

Firstly, ensure you have the required 'mixture' of coolant/water (must have required coolant).
Second, I would recommend you re-test all the cooling system sensors again (make sure they're within specifications), in case a new one is faulty.
Third, ensure the new thermostat was of the correct temp setting (they all differ), so that it opens at the required time. Most cooling systems operate within 90 - 100degC.
Fourth, make sure the radiator (and associated hoses) aren't blocked.
If your temp gauge is reading higher than normal, but NOT in the danger zone...then this can be considered normal (especially if you've replaced with new components) and nothing to be concerned about.
However, if the temp gauge IS in the danger zone....then this suggests the coolant is not flowing through the cooling system properly.
If all above components test ok, then it's possible your water pump may not be pumping enough volume.

Testimonial: "I appreciate your help...Maybe I should just relace the water pump, that would be the last thing that I would need to replace."
