Your water pump may be getting ready to go out or your timing chain may soon break. Often the first problem can lead to the second problem. (not neccessarily at the same time) Check your radiator hose after idling a couple of minutes from cold startup. Shut off the engine, raise the hood, and carefully (making sure that you don't touch anything that may have become too hot) squeeze the hose that connects to the radiator. If it feels very flimsy, soft, or appears to be abnormally larger than further down the length of the hose you may just need to replace the hose. Make sure that the hose clamp is snug. Check your coolant level, if coolant is needed be sure to add the same color coolant that is already in your radiator. Mixing coolants can lead to much bigger woes in a short amount of time.

Why do i have lack of heat and low heat gauge reading on a dodge caliber 2007 2.0 and 115,000 miles s

I would bet the check engine light is on as well?

Low temp gauge and the lack of heat is typically the result of a bad thermostat. I would also bet that you fuel economy has nose dived as well. A new thermostat should get the engine running at the correct temp and restore the heat to the passenger compartment.

2004 santa se 2.4L Temp gauge reads normal, but heat from vents excesivlly hot.will not start after running for a while until it sits 1/2 hr.

There is a blower control resistor (manual system) or a blower transistor (automatic temp system) located behind the glove compartment in the HVAC box and this is a high failure item.

replace thermostat do not just remove old one as motor will still over heat at mid to high speed and fuel injection requires a certain temp range to operate correctly

Isuzu pup temp gauge reading high. Temp transmitter, radiator and thermostat all have been replaced. What else to try?

You would need to know if the engine is actually running above 220 degrees, or if the gauge is faulty. You could run the engine with the thermostat out as a test, and also use an inferred thermometer to measure the actual engine temp and compare that to the gauge on the dash.

2004 Jeep Grand Cherokee temp gauge high when heat is on

If your "check engine" light is turn on, I suggest scanned the PCM to know exactly what fault code is stored there. Additionally, could be some problem with the "temp sending unit".

Keep us updated.

Car is running hot (temp gauge rises above normal)

Try the overflow tank cap. The seal will go bad and not hold the psi causing the water to flow out this is something you will not always see which will cause the engine to overheat or temp gauge to rise. Also the thermostat could be sticking and cause the temp gauge to rise. Are the fans turning on when the temp gets high? If so then I would resort to the above first. If the fans are not coming on, the relay or fan/s could be the problem.

No heat

You need to bleed the cooling system of excess air and add aditional antifreeze.
