The internal combustion engine in a Jaguar produces a significant amount of heat during operation. An elaborate cooling system is installed along the engine to dissipate heat from the engine. Failure to dissipate this heat overheats the engine, which occurs due to a malfunction in the cooling system. Understanding the malfunction and rectifying it in a complex European vehicle like a Jaguar requires an expert, experienced technician with advanced tools. EuroService Automotive in Warrenton provides you with this expertise in repairing your Jaguar’s engine overheating problems. However, it’s still important to know the underlying causes behind this malfunction and symptoms associated with it so you’re able to look out for warning signs.
Underlying Causes Behind Engine Overheating in Jaguar
- Leaks in the cooling system or irregular maintenance can create a shortage of coolant needed to cool the engine, causing engine overheating.
- The thermostat regulates the coolant flow throughout the cooling system. When it malfunctions, coolant flow stops, halting the cooling process and causing the engine to overheat.
- The water pump pushes coolant through the system, and when it malfunctions, the cooling process stops, which skyrockets the engine temperature.
- The radiator dissipates heat from the engine, and when its fins become clogged, the heat can’t escape.
- Similarly, if the coolant fan, which pulls air to cool the hot coolant, malfunctions, the cooling process stops, and the engine overheats.
- When the heat gasket fails, it allows hot combustion gases to enter the cooling system, rapidly heating the coolant. This causes an imbalance in the cooling system, leading to an increase in engine temperature
8 Symptoms Associated with Jaguar Engine Overheating Problems
When a cooling system malfunction occurs, the vehicle displays various warning signs, including increased engine temperature. Understanding these signs can help you make an informed decision about cooling system repair during Jaugar services. Here are 8 symptoms our expert technicians at EuroService Automotive suggest to watch out for:
1. Rapid Rise of Temperature Gauge
The thermistor sensor within the cooling system measures the engine temperature. When the engine temperature rises due to a cooling system malfunction, this sensor catches the change and sends signals to the Engine Control Unit (ECU). The gauge steadily climbs to the red warning zone, indicating to the driver that the engine temperature is rising beyond the safety limit.
2. Smoke Coming from Under The Hood
When the engine temperature exceeds the safety limit, the coolant in the system boils. This creates high pressure and bursts the coolant cap, allowing coolant to steam. Leaks in the system also let the steam escape. This steam resembles thick white smoke that comes out from under the hood.
3. Sweet and Syrupy Smell
The coolant leak causes the engine temperature to rise. When the leaked coolant drops on the hot engine, it evaporates. The primary compound in the coolant, ethylene glycol, is released as a vapor and causes a distinct, sweet, syrupy smell reminiscent of candy.
4. Coolant Puddles Under the Vehicle
Excessive engine heat can cause hoses, radiator end tanks, the water pump seal, the reservoir, or the heater core of the cooling system to rupture. This causes the coolant to drip or spray out. As a result, puddles of green, pink, blue, or orange fluid get deposited beneath the front of the car after it has been parked.
5. Unusual Engine Noises/ Knocking
When the engine chamber gets extremely hot, it ignites the air-fuel mixture prematurely at multiple points before the spark plug ignites. This causes pressure waves that result in a metallic knocking sound in the engine.
6. Decrease in Engine Performance
When the engine control unit detects engine overheating, it puts the vehicle into limp mode to reduce heat generated by engine operation. This decreases the engine performance.
7. Burning Oil Smell
Engine oil lubricates the engine, and an excessively hot engine can cause it to burn, producing a distinct oil-burning smell.
8. Check Engine Light
Upon detecting an overheating engine, the ECU generates fault codes related to the overheating. This results in the check engine light and the temperature warning light being triggered in the Jaguar.
