We designed and developed this upgrade kit so that you can have an early LOW ENGINE COOLANT warning system installed on your Volvo models mentioned above. From the day these models were introduced to the USA market- there has been an issue since there is no factory installed low coolant warning system. It is UNFORTUNATE, but many of our customers have had to deal with the cost associated with complete engine replacement due to loss of coolant and engine OVERHEATING.

We are proud to offer this solution to you . You will have a low engine coolant warning system on your Volvo after installing this upgrade kit.

Please UNDERSTAND - this is NOT a repair solution for OVERHEATED engine. If your vehicles engine is overheated- it has to be replaced first. Then you install the sensor .

Please understand that the actual design of the sensor may differ from the picture that you see.

Please understand that the sensor is monitoring coolant level and sending you a message that there is an issue. If the message comes after you have installed the sensor - there is a possibility of a coolant loss.
