I have an 05 Kia sorento. It is showing signs of over heating, I checked fluids changed coolant and there are no leaks. Thermostat only goes to the middle.

Generally and engine heats up a little more when you shut off engine and it may be boiling out into over flow tanks as vapor (no leak) when it makes that sound. A overheated engine feels very hot when you open the hood, gauge works but maybe not accurately.

I have a 02 Grand caravan that has new radiator, termostat, one new fan. the temp gauge goes up to max hot the drops right back down in seconds. what could be the problem?

it could be you have an air lock in the cooling system
remove the rad cap from the rad, start the engine and let it run until the coolant drops (add to fill it back up) or until the coolant boils out of the rad spout.

maybe pull the heat sensor. -replace it OR clean it off, reinstall it.

Ford Taurus heater only blows cold air

remove the wire to the temperature sender unit and earth it out on the head. Turn on the ignition and see if the gauge goes to hot quickly. If it does then the problem will be in the sender unit so replace it. They are a resistance material inside that has high resistance when cold and the resistance becomes less as the water heats up so letting more current flow through the gauge so it goes up. They are prone to failure in an overheat situation. From your description the sender unit has failed inside

Running hot?

2 possible things. 1st(cheapest) you have air in cooling system. Need to burp it. 2nd(expensive) you may have blown head gasket. I tend to think air is in cooling system and your level is low.

My 1991 volvo740 bertone coupewater temp. gauge doesn"t move at all after the engine is warmed up. The upper hose is hot. The water in the resevoir is cool as is the bottom radiator hose. There was...

The thermostat is on top of the engine, just aft of the upper radiator hose. The temperature sensor (first one, closest to the front of the engine) is the one responsible for the coolant temperature gauge. It's an NTC with two resistors in it - one for the sensor gauge, one for the ignition computer. There is a second one for the Luftmassenmesser Hidtstraht system, bottom right side under the intake manifold.

If you have a drop of anti-boil on the water pump - it is coming from the weep hole and this is indicative of failure of the internal seals on the pump and it must be replaced.

There is a possibility that the thermostat is stuck closed, which can be easily verified in cool weather by cool air coming out of the vents at normal operating temperature. Check the heater core hoses - one should be warm.

Be careful when working on the cooling system - it can scald when hot! Always work on it with the engine cool to the touch and never put cold anti boil in a hot engine.

Checking the temp sensor is easy - remove the connector and place a 68 ohm resistor across both terminals (or one to ground if it is a single spade connector). The temp gauge should read approximately 3/4 across the scale. Don't short it to ground as this could destroy the sensitive coil inside the sensor. If no reading occurs, then the gauge or wiring is broken.

Temp gauge goes over hot and clear down past cold mark. water boiling fans working car stalled and filled coolant ran normal then

You should check and top of if necessary your coolant reservoir at least once a month. Other fluids to check at least once a month are, brake fluid, engine oil, transmittion fluid (automatics to be checked warm, idling in park).
Overheating is very harmful to your cars engine, and should be avoided/prevented at all cost. Once an engine shuts off due to excessive temperature, damage has already been done.

Overheating,reserve coolant tank boiling I have a 2000 Ford Taurus with the similar problem. I had my water pump replaced then this started.

Ford 2000 Taurus

To solve the problem you have the things to do in this order;

) When the engine is cold top off the radiator with fluid. (When the pump was replaced the fluid should have been also)
) Make sure the radiator fluid has anti-freeze in it. This is also anti boil also !
) Add fluid to the overflow reservoir.
) Make sure the drive belt was replaced on the water pump.
) With the engine running, you can add fluid to the radiator for the first minute or so. You want to get air pockets out.
) Replace radiator cap.
) Let car warm up. When it's hot you should get the radiator fan coming on.
) When it get hotter the air-conditioning fan may come on.
) If the fan does not come on, the heat sensor is probably bad.
) If all fans come on, and it overheats, you may have a bad thermostat. Trace the upper radiator hose to where it connects to the engine. That's where it located.

Do not operate the engine when it overheats, You will damage the head gaskets and cause radiator fluid to leak into the cylinders.
If you smell radiator fluid in the exhaust fumes, it may already be leaking.

Engine runs hot on 2001 Stratus R/T 3.0L V6

Hello, as previously suggested by my collegue it appears you have an air lock. Have you tried parking the vehicle on level ground, from cold with radiator cap off start the car and leave it idling. Make sure the fluid/coolant levels are o.k. and let the engine reach operating temp. Keep some warm water handy and watch/listen the water/coolant system (Keep a safe/sensible distance from radiator) hopefully after a while the system will bubble and boil up let it settle for a few seconds and then top up with very warm water do this until it hopefully stops belching out of radiator. Replace cap and hopefully top and bottom hoses will be warm. Oh! nearly forgot keep all heater controls on hot with blower on full..(Inside the vehicle)
Finally I'm not joshing but is the thermostat in the right way round and functioning correctly? to test drop it in some boiling water it should open almost immeadiatly.
sorry for the epic but I'm here to help and hopefully save you time and money.
Good luck and a Happy New Year to you and your family!
