I am having an issue with my s-10. It runs hot but is not overheating. It started when I replaced the temperature sending unit and thermostat. I put in an additional thermostat to make sure the first was not defective. I replaced the radiator a year and a half ago with a brand new one. Flushing the coolant has not fixed the problem either.
The truck has had performance issues. In the mid range power, the truck stutters and seems to miss. I think that this issue is related to my cooling issue because the power stutter is more pronounced when the engine is warmed. I ran a compression check to see if my power loss is due to a lack of compression in one cylinder but all 4 cylinders have the same compression.
The fan clutch seems to be fine too. Any thoughts?
