Having the same issue with my 2016 Camaro. After a few short 30 mile trips coolant gauge stops working and fan runs full blast. Reoccurring issue last couple of weeks. Have to disconnect the negative battery cable to reset. Added coolant, which wasn’t needed and also replaced relay. Looking for answers.
Why is the transmission cooler in my car overheating?
Most automatic transmission vehicles utilize a fluid cooler inside the radiator to help remove heat from the transmission fluid. When this cooler fails it will allow transmission fluid to contaminate the coolant inside of the cooling system which inhibits the heat transfer of the coolant.
When does a car coolant fan shut off?
The coolant fan will continue to run until the engine temperature cools down to a specific predetermined level. Once the temperature reaches this cooling stage, the coolant fan will shut off. Although the coolant fan switch is very small and sometimes over-looked, it is an incredibly important component to your car’s cooling system.
What are the symptoms of a bad thermo coolant fan switch?
Several symptoms may point to a bad or failing thermo coolant fan switch. 1. Engine overheating Engines generate an enormous amount of heat and as a result are subjected to very large temperature swings if this switch does not operate effectively.
Why is my Honda radiator fan not working?
If the radiator fan begins working, this is an indication that the fan relay is bad. If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.
