How Much Does It Cost to Replace a Radiator in a Semi Truck?

Replacing a radiator in a semi truck can be a costly endeavour, with the price varying depending on the type and model of your truck. The cost of replacing a radiator in a semi truck can range from $650 to upwards of $1,200, with labor costs accounting for the majority of the expense.

To start, it’s important to understand why it’s necessary to replace a radiator in the first place. Semi trucks generate a lot of heat due to the amount of energy they consume when running.

The radiator is responsible for cooling down the engine and preventing it from overheating. Over time, radiators can become corroded or clogged, leading to diminished cooling capacity and ultimately requiring replacement.

When selecting a replacement radiator for your semi truck, it is important to select one that is properly sized for your engine. Radiators come in various sizes and shapes so it’s important to match up the size and shape of your existing radiator with its replacement. Additionally, you will need to consider whether you need an OEM (original equipment manufacturer) part or an aftermarket one.

The labor cost associated with replacing a radiator in a semi truck depends on several factors such as the make and model of your truck, as well as where you are located. As such, it’s important to get quotes from multiple qualified mechanics before making a decision on who will do the work.


Replacing a radiator in a semi truck requires careful consideration to ensure that you are getting an appropriate replacement part that meets your needs and budget. Depending on make and model, labor cost can range from $650-$1,200 while parts may range from $50-$500. It is advisable to get quotes from multiple mechanics before making any decisions regarding repair work on your semi truck’s radiator.
