The installation procedure of this upgraded tank on your vehicle can take about one hour give or take , without visiting a repair facility or service garage. On the Turbo charged cars- it may take a little bit longer. The idea behind the low coolant warning is not new, and most of the Volvo models were equipped with this feature, but not yours.

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 had suffered an overheating condition - the engine repairs have to be addressed first. Then you install the sensor .

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.
