SOURCE: HEAT NOT WORKING WHEN IDLE

Sounds like you may have a thermostat stuck open. Try taking a piece of cardboard and placing it in front of the radiato. Don't block it completely, but just limit some of the airflow. See if this helps.

SOURCE: crank but does not start (Error code P0642)

p0642 = sensor reference voltage a circuit low voltage
p0300 = means random misfire
check firing order connections and must be in place.
check also cables especially the high tension cable and coils for required resistance.
primary = 1.0 to 0.5 ohms
secondary = 900 to 11,000 ohms (as requires per model)

Sounds as if the electric fan on the radiator isn't coming on. Most radiator shops also work with A/C systems and may be more qualified to do the work. However, any good "normal" repair shop should also be able to diagnose the problem. Try not to drive it very far and keep close watch on the engine temperature. An overheat can do extensive (expensive) engine damage. If you have a fill cap on the radiator, fill it there (when cooled down) filling the recovery bottle may not be sufficient to get coolant into the engine.

When you said you replaced everything, did that include the temperature sending unit?
The temperature sensor just operates the cooling fan or fans for the radiator.
The temperature sending unit operates the temperature gauge in the dashboard. If that thing is faulty, the gauge won't work right.
If you did change the sending unit, it could be possible that the computor is screwing it up, but in my 41 years as a mechanic I never heard of it, when a computor goes, nothing works.

Temp. gauge reads high some times. but the motor really isnt hot


It sounds like the coolant temperature sensor is beginning to fail. It is highly unlikely that the in-dash gauge is a problem. The coolant temp sensor inputs to the computer affecting everything from radiator fan speed, engine fuel/air calibration and a variety of other parameters.

Be absolutely certain to "burp" every bubble of atmosphere from the coolant system too. Air bubbles have the amazing ability to prevent coolant flow and will cause all sorts of problems, especially if the bubble wants to hang around the temperature sensor location.

Normal operating temperature is going to be around 210 F.

Most Autozone, Advance locations will read engine problem codes at no charge, so drop by one of those locations and let them read the problem code.

My guess will be the coolant temperature sensor. Then have the problem code reset, remove all air from the coolant and let us know how this worked.

You will need to change your thermostat as it is stuck and is not responding correctly to temperature changes. Have your mechanic change the thermo, do a flush of the system and all should be good again.
