![]() ![]() Your 200 will be equipped with a temperature warning light and/or a temperature gauge. ![]() Here are the most common symptoms that your Chrysler 200 is overheating. If any part of this system fails, your 200 will eventually overheat. Radiator Hoses– Connect the radiator to the water pump and engine block.It is needed when driving at lower speeds. Radiator Fan– Your 200’s radiator fan pushes extra air onto the radiator when the engine coolant gets too hot.Radiator– Pulls heat from the coolant before it cycles back into your 200’s engine.Thermostat– The thermostat opens up once the engine reaches operating temperature and allows coolant in.The coolant starts in the radiator, enters the engine, pulls heat out of the block and heads, and returns to the radiator to be cooled again. Water Pump– Your 200’s water pump pushes the coolant through the entire system.Your 200’s cooling cycles engine coolant from the engine through the radiator. ![]() If your Chrysler 200 is overheating, the first thing you should do is check the coolant level. A blown head gasket, engine block, or cracked head are much more expensive than a thermostat or water pump. Ignoring an overheating engine can lead to serious engine problems. If your 200 is overheating, stop driving it immediately to avoid damaging the engine. Common symptoms of overheating include smoke coming from under the hood, a pegged temperature gauge, and (eventually) a blown head gasket. Lower PSI will make it send coolant to the expansion tank too soon, higher PSI will put the system under too much pressure with the risk of blowing a hose, damaging the pump, probably even the head gasket.One of the worst problems that can happen to your Chrysler 200 is overheating. I could be possible to have a cap tight without no leaks, but having its valve damaged, which would lead to overheating as well, since the cap won't be managing system pressure as it should, probably sending coolant to the system's expansion tank.īe careful when replacing caps: the new one should have the same operating temperature AND system pressure (PSI) than the one original for the car. Loose cap = possible leak from the cap (liquid or evaporated coolant) OR cap internal valve damaged or not sitting well in its base. If the system is "open" somewhere that could suck air, it is also an engine overheating risk point, since air pockets interferes with the system function as well. If there is a leak, pressure is lost, boiling point is reached, increasing the leak and loosing coolant to the extent to get the engine overheating because a lack of it. When the engine reaches its operational temperature, coolant is just a pinch below boiling point (thanks to be under pressure). And other less talked effect: rotting of metallic parts around the radiator, especially the support underneath it (even more pronounced below the rubber supports).Ĭooling system is an under-pressure, isolated system that shouldn't have leaks and/or air intake. Short answer: engine overheating by loosing coolant. You will be fine as long as you have liquid in your reservoir and you are not living on very high altitudes. In addition, if you have a leak in your system, you can loosen the cap and drive slowly/short distance while avoiding pressure buildup Because if you have a leak, with pressure you will loose liquid much faster than evaporation or through the cap. Because pure water boils at 95C at 1500M and glycol in your coolant already increases the boiling temperature (50-50 mixture has boiling temp of 106C at sealevel) and normal operating temperature of engine is between 85C-95C (on most car the needle sits on 90C mark when car warms up to normal temp). You have to be at altitudes over 1500M for your coolant to boil at normal operating temperatures. The information about boiling and destroying your engine is possible but unlikely to happen as long as you are careful. Because system is under pressure and the reservoir is the highest place where the liquid is, it would just leak out if it is not tight enough. I can't think of any reason for coolant to evaporate. If your liquid level is going down (remember to check with cold engine), this means you have leak. If you do not see any leaks, you are good to go. The most used coolant liquid is pink/red color (see your car manual for the color/type) so it is easy to see even after it dries, therefore easy to identify leaks. If you see liquid around your radiator cap, then it is loose or broken and must be fixed. Then tighten the cap and run the engine until it reaches operating temperature. Open the hood, check that your radiator is fully filled by opening the cap. ![]()
