Vehicle overheating tips

If your vehicle engine coolant temperature gauge indicates overheating, if you experience a loss of power,or if you hear a loud knocking or pinging noise, the engine has probably overheated. You should follow this procedure............

Pull safe off the road, stop the vehicle and turn on our emergency flasher. Put the transmission in "P" (automatic) or neutral (manual) and apply the parking brake. Turn off the air conditioning if it is being used.

If coolant or steam is boiling out of the radiator or reservoir, stop the engine. Wait until the steam subsides before opening the hood. If there is no coolant boiling over the steam, leave the engine running. CAUTION: To avoid personal injury, keep the hood closed until there is not steam. Escaping steam or coolant is a sign of very hing pressure.

Visually check to see if the engine drive belt (fan belt) is broken or loose. Lock for obvious coolant leaks from the radiator, hoses, and under the vehicle. However, note that water draining from the air conditioning is normal if it has been used. CAUTION: When the engine is running, keep hands and clothing away from the moving fan engine drive belt.

If the engine drive belt is broken or the coolant is leaking, stop the engine immediately and call your mechanic of assistance.

If the engine drive belt is okay and there are no obvious leaks, you may help the engine cool down more quickly by running it at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed.

Check the coolant reservoir. If it is dry, add coolant to the reservoir while the engine is running. Fill it about half full. CAUTION:Do not attempt to remove the radiator cap when the radiator are hot. Serious injury could result from scalding hot fluid and steam blown out under pressure.

After the engine coolant temperature has cooled to normal, again check the coolant level in the reservoir. If necessary, bring it up to half full again. Serious coolant loos indicates a leak in the system. You should have it checked as soon as possible at your mechanic's workshop.

Good luck.

My car said "engine hot

Full coolant level does not mean your engine cannot overheat. You need to fix the problem as overheating will destroy the engine if not addressed.

The radiator cooling fans must be working, as must the water pump. The thermostat must also be working properly.
There must also be no air in the cooling system as air locks will impair water flow. When cooling systems are drained fully or partially and re-filled air in the system must be bled out using the correct bleeding procedure for the particular engine/cooling system. Failure to do this properly will lead to overheating.

If you ONLY see the overheating warning when running your aircon you need to check that the electric radaitor fans are kicking in at idle when you switch on and run the aircon and the engine has been warmed up some. If they do not start operating when the a/c is running you will get an overheating condition in normal driving conditions.

If the radiator fans are operating normally and you still get an overheating warning when the aircon is on or off the most likely culprit is a faulty thermostat in the engine's cooling system which will need to be replaced.

If you have either a faulty thermostat or if the water pump in the cooling system fails you will get continuous overheating whether the aircon is on or off.

Hello... I got problem with my honda odyssey. For the past 3 days, if i start the engine, after 5 min the temperature will goes up to HOT and engine indicator light-up. I turn-off the engine and then start...

Your English is very good.

From what you have described, which is a rapid over heating of the radiator coolant fluid and therefore a hot engine condition, it would appear that the thermostat in the engine's cooling system is faulty.

If the thermostat is sticking in the closed or nearly closed position temporarily, there will be no flow or very little coolant flow between the engine and the radiator and the engine will overheat.

You have advised that after the engine is shut off , and radiator coolant fluid has cooled, you re-start the engine and drive the car without the overheating condition occurring again and the radiator coolant temperature is normal. This time there is no overheating because the thermostat is working normally.

You should have the thermostat replaced as soon as possible because allowing the engine to overheat can cause very expensive engine damage.

If you had a continuing overheating condition then I would suspect both the thermostat and the water pump. However as the overheating seems to be only temporary, and clears itself after you have shut down the engine and re-started it 10 minutes later (without further overheating arising) then I think you only have a faulty thermostat.

Please also check that the electric fans which draw air through the radiator are operating. These run on a temperature sensor and will switch on automatically once the radiator coolant fluid reaches a certain temperature and then switch off again when the fluid temperature reduces. You will hear them running once they start up. If these fans are not working the radiator coolant can quickly overheat in various driving and temperature conditions because there will be insufficient air flow through the radiator to cool the fluid. If the temperature sensor is faulty or has died, or if the electric motors running the fans are faulty, the fans will not operate.

I hope this helps.

MY 2001 CHRYSLER LHS IS OVERHEATING. THERE IS NO VISUAL LEAKAGE. I PUT WATER IN IT AND IT DID NOT RUN HOT, HOWEVER, AFTER PUTTING WATER AND COOLANT, AFTER 10 MINUTES OF DRIVING, IT RAN HOT. WHAT CAN...

1. The thermostat in the cooling system could be sticking and need replacing. If it sticks in the closed position coolant cannot flow to and from the radiator and the coolant circulating through the engine will quickly overheat.

2. The water pump may be on its last legs and require replacing. If the pump has failed (and they do) the coolant will not circulate through the engine and radiator as it is designed to do and it will overheat quite quickly.

3. There could be a build up of debris in the cooling system that is impairing coolant flow through the engine. This can occur if the cooling system is not fully flushed out every 2 years and the coolant replaced. The cooling system must then be bled to remove all air. When replacing the coolant you MUST use the correct product as specified by the manufacturer and in the correct mix.

4. Radiator caps must be sound (and the correct specification) to ensure coolant does not escape and result in a low coolant condition and then overheating.

You need to get your car to a competent mechanic quickly to check and rectify the problem. (You may find it is only the thermostat as this is a common problem with time and usage.) Driving your car with an overheating condition WILL result in expensive engine damage. The head gaskets will blow and the heads on the engine will crack. Additional engine damage is also possible.

Cooling systems must be well maintained to prevent overheating and consequential engine damage.

Fan doesn't run while in idle and begins to over heat until I start driving agin then it cools back down to normal. Also the fan runs when engine is off and drains the battery.

The fan is only supposed to come on when there is excess heat .. in normal driving conditions it doesn't start. When you start your car in the morning the fan won't come on because the engine is cold.

With a hot engine - and it depends how hot the engine is - the fan will only kick in to prevent overheating. In heavy slow moving traffic or a traffic jam, the fan will kick in if needed.

The air flow through the radiator is usually sufficient -in normal driving conditions - to cool the engine.

When you park up and the car has a hot engine, the fan will kick in. This is perfectly normal. It is caused by a surge of hot coolant triggering the fan sensor. Perfectly normal.

The fan then should cut out after a while .. maybe 2-3 minutes at the most. If the fan runs continuously that suggests a fault in the temperature sensor switch.

Next time - wait by the car and see how long it takes for the fan to quit after you have parked up. It should stop of its own accord after a couple of minutes.

If the fan cuts off after a short while, and your battery is becoming drained, that's probably a battery or alternator fault.

Remember: when you start the car the fan won't kick in at idle speed because the engine is COLD, and there is no reason for the fan to start up ..
The fan WILL kick in for a couple of minutes after you have parked the vehicle and the engine is hot

CHECK TO SEE IF THE FAN RELAY IS FUNCTIONING BY SWAPPING IT WITH ANOTHER LIKE THE WIPER RELAY IF THEY ARE THE SAME. IF THE WIPERS WORK WITH THE A/C RELAY IN IT'S PLACE, THEN TRY REPLACING THE FAN FUSE. IF NONE OF THESE METHODS MAKE THE FAN TURN ON THEN REPLACE THE COOLANT TEMP SENSOR LOCATED NEAR THE UPPER RADIATOR HOSE INLET TOWARDS THE FRONT OF THE ENGINE. HOPE THIS HELPS YOU FIND THE SOURCE OF THE PROBLEM. LET ME KNOW. GOOD LUCK AND THANKS FOR USING FIX-YA.
