While in recent years Maserati models have been beset with a whole host of technical issues resulting in recalls, there is no doubt that the Italian manufacturers know just what a good car looks like. With modern, futuristic designs that also seem to retain an element of classic car styles, a Maserati is all clean lines, curves, and sex appeal.
However, one thing that certainly isn’t sexy is a failed or leaking thermostat in your Maserati. An issue such as this can cause a whole host of problems down the line, so it is best identified and dealt with quickly. In this article we’ll be taking a closer look at the purpose of a thermostat in your car, as well as exploring some of the signs of thermostat failure.
What is a Thermostat?
Similar to a thermostat in your house, your Maserati’s thermostat is in charge of regulating the flow of coolant through the engine to prevent overheating. The thermostat is able to regulate the coolant levels in the engine by opening and closing with changing heat levels. When your car is off, for example, or still at a cooler temperature, the thermostat will remain closed, preventing coolant from entering the engine. When the engine heats up, the thermostat will open, allowing the coolant to lower the engine’s overall temperature.
Common Reasons for Thermostat and Cooling System Leakage
Because the thermostat and coolant systems work hand in hand, a problem with one often indicates problems with the other. In this list we’ll be exploring some of the most common causes for issues with these systems.
1. Coolant Leaks
If you find coolant leaking from the exterior of your Maserati, then it is usually from a leak of either the radiator or heater hoses. If the coolant leak is more towards the front of your car, then the culprit may even be the radiator itself, which can often rust and develop holes, allowing the coolant to leak out.
2. A Stuck Thermostat
The valve which controls whether the thermostat is open or closed can commonly become stuck, and can result in an engine either overheating or running cold. This can cause an excess or unnecessary build-up of coolant in the engine or in the coolant valves, potentially causing any weak spots in the system to leak.
3. Cracked Thermostat Housing
If the housing of your Maserati’s thermostat is no longer watertight due to damage or cracking, then it can cause coolant to leak out of the system and in to your car. The same can be said for many of the gaskets found near to the thermostat.
4. Faulty Thermostat
If the sensors in the cooling system are faulty, then the thermostat may open and/or close at inopportune moments. This can lead to sudden drops or unintended increase in temperature, which can put strain on many of the other systems in your car.
5. Regular Refills
Having to top up your car’s coolant regularly may also be a sign that you have a leak in or somewhere around your thermostat. Leaks within the interior of the car can be difficult to find, so if you think a leak is likely but you cannot visibly see it, then it’s best to take your Maserati in for service.
6. Milky Oil
If when going to check or refill your oil you notice it appears paler, almost like chocolate milk, then it’s likely that you have a leak somewhere in your coolant system. The whitening in the oil is down to coolant that has been able to enter the engine oil through your cars’ piston rings. This can be a sign of problems with your head gasket, which should be addressed as soon as possible.
