I have a 2000 Toyota Camry from Carhop and I've had it less than 3 months. A month ago, the engine blew and the water pump and timing belt was replaced (at least to my knowledge.) Last night, I slowed to a stop while at a toll booth and my car started to rock and shake. When I pulled off, it stopped. When I made it home, my car overheated – really, really quickly – and stalled. The next morning, I went to the gas station, less than two blocks from my house, and my heater stopped working. An hour later, it was fine. My fiancé checked the coolant levels and everything was fine. My car conti

The most common reasons a Toyota Camry is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
The most common reasons a Toyota Camry heater isn`t working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.
There`s an issue with the radiator: Radiator issues, including blockages, fan issues, and leaks all could cause a car to overheat.
One common reason engines overheat while idling is a faulty or broken cooling system. This could include problems with the radiator, water pump, or fan belt. If any part of your car`s cooling system is not functioning properly, your engine may be at risk of overheating.
If your coolant level is a-okay, but your car heater is blowing cold air and your engine is overheating, then you have a clog in your cooling system. Conversely, if your engine temperatures are unrealistically low after a drive, your thermostat is likely the culprit.
One of the most common issues with a heating system not functioning is dirty air filters. If your air filters are extremely dirty, then the airflow can be blocked. Check for clean air filters, vents, and registers. Make sure there are no rugs or furniture blocking vents or registers as well.
How long can a car overheat before damage occurs? It only takes 30-60 seconds of overheating for permanent damage to infiltrate a vehicle. As soon as you notice signs of overheating, you need to act. Failure to do so might result in troubles like coolant leaks, damaged radiator caps, and a faulty cooling fan.
A Broken Radiator Fan
If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it`s most likely due to a broken radiator fan. When the coolant goes to the radiator, it`s spread over a large surface area to cool it down.
Pull over and shut off the car. Allow the engine to cool for at least 15 minutes. Keep an eye on the temperature gauge, as it should move back to a normal range as the engine cools. While you`re waiting (and watching the gauge), put together a plan to get your overheated engine checked out.
Wait until the gauge moves back to the normal range or the light extinguishes before you open the hood. DON`T wait for it to get better on its own. An overheating engine won`t repair itself, and you should bring your car in to Jiffy Lube as soon as you can.
Repeated overheating can be a sign of serious engine damage. Repeated use of an overheated engine can accelerate that damage rapidly. In extreme heat, core parts of the vehicle`s engine can crack, warp, and fail — resulting in instant death to your vehicle`s powerplant.
One way to check for proper coolant circulation is to check the upper and lower radiator hoses. The upper radiator hose should be hot, around 190–200 °F. (The safest and most accurate way to get this temperature reading is with an infrared thermometer.)
A blocked heater core might restrict coolant circulation, causing the engine to overheat. In any case, keep an eye on the temperature monitor if you decide to drive with a blocked heater core.
If an engine “feels” cold, or “normal” but the dash gauge shows overheating, you could have a faulty temperature sensor and/or gauge. No cabin heat could be due to low coolant, blocked passages, faulty heater control valve and/or faulty blend door(s) in the dash ventilation network.
A malfunctioning thermostat can make your heater or air conditioner unable to turn on. In most cases, this indicates the wiring has failed. Normally, electrical wires transmit messages from the thermostat to the HVAC unit, such as telling it when to turn on and what temperature to make your house feel.
If your heater doesn`t start, chances are the problem stems from having a dirty furnace. Having dirt on your blower motor or flamer sensor could render your furnace unable to perform. When the blower motor is too dirty, it won`t pass enough cool air to the heat exchanger, leading to equipment failure.
If you think the cause for your car heating not working is related to the blower fuse, be sure to replace it with one of the same amperage. The fuse may have blown due to age, or it may suggest an underlying problem. If the replacement fuse (of the same amperage) does not blow, you may well have identified the problem.
The heater core in your car works like a radiator to move hot air through your car`s vents. Damage to your heater core will have some telltale signs. Excessive condensation on the inside of your windows tends to indicate a leak. Your heater will also only give off lukewarm or cold air if your core has a problem.
Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle`s cooling system.
Frequent fault symptoms are: Higher idle speed. Increased fuel consumption. Poor starting behaviour.
Loud popping, knocking, and stuttering noises from the hood of your vehicle are cause for concern, and could be a sign of major engine damage.
If the water pump in your engine isn`t doing its job, you`ll likely notice the car overheating when idling or headed down the road. The water pump does just what you would expect by pumping coolant through the system.
Overheating and a rough idle that happen at the same time can be caused by a blown head gasket. A blown head gasket means that the cylinder is not sealed, so the compression from the bad cylinder leaks into the cooling system. This causes a rough idle because the cylinder is not working properly.
Driving your car when it`s overheating can cause serious – and sometimes permanent – damage to your engine, so it`s best to stop driving as soon as possible. Pull over and away from oncoming traffic, then turn off the engine. Open your hood (or call for help).
