Faulty Thermostat

Thermostat failure is the most common cause of Code 89. The ECM may display a warning code when it believes something is wrong if your engine runs hot or cold due to a faulty thermostat.

Coolant temperature is regulated by a thermostat during engine operation. Cold weather prevents hot engine coolant from entering your radiator by closing the thermostat.

Warm engines allow coolant to flow through their systems as soon as their valves are opened.

A thermostat can wear out over time, particularly on Vauxhall vehicles due to normal wear and tear. Over time, the plastic housings of the thermostat can crack, leaking coolant.

A cracked or faulty thermostat housing may cause your Vauxhall Mokka to run hot.

Bad O2 Sensor

An oxygen sensor measures oxygen in an engine’s exhaust. Prior to or after them are catalytic converters, which reduce harmful emissions.

After replacing the thermostat on your Vauxhall Mokka, if the code 82 persists, one or both oxygen sensors may need to be replaced.

What Is The Best Way To Fix Vauxhall Mokka Code 82?

The thermostat should be replaced as soon as possible. If you don’t want to do the repair yourself, you can take your Vauxhall Mokka to an auto repair shop or to your nearest Vauxhall dealership.

Your thermostat should be replaced if you have overheating and the code 82 problem.

In the event that your thermostat is fine, it may be your oxygen sensors that are causing the problem. These should also be replaced.

Coolant Leak

If you see coolant leaking from somewhere, your thermostat may be malfunctioning.

Clicking Sound

When your Mokka’s thermostat is malfunctioning, you may also hear a clicking sound. This problem may be caused by a malfunctioning thermostat. If your engine overheats, it can cause damage.

Thermostats That Don’t Work

Having a Vauxhall Mokka code 82 may have you wondering what other signs you should look for. Bad thermostats usually cause this code. Other signs of a malfunctioning thermostat include:
