Your Classic Mini’s cooling system has used the same basic type of radiator since it was made until the twin point injected cars came out. When the radiator was moved to the front of the car, the cooling system was changed. You should know that the original Mini had an 848cc engine that was made for the small roads in the UK. This is important to know.

Then, as the demands for more engine power and capacity grew, so did the need for a more efficient cooling system, which made it more important. Take a look at some of my best DIY radiator flushes in this post.

How Much Is A New Radiator For A Mini Cooper

A radiator function is very important. The radiator stops the engine from overheating. It gets hot when your engine runs. In fact, you already know that coolant moves through the system absorber and takes the extra heat out of the engine.

Between $80 and $764, you can get a new radiator for your mini cooper for about that price. It all comes down to the brand and the quality of the thing you buy.

That is the material that was used to make the thing.

Mini Cooper Radiator Replacement Cost

Mini Cooper radiator replacement costs can range from $80 to $764. The cost of labor is between $221 and $279, and the cost of other parts can be as high as $416. You should know that taxes and fees are not included in this price range. It may not take into account your vehicle type or where you live.

Classic Mini Fletcher Radiator Review

The Fletcher alloy radiator was made by M2 Motorsport to be a direct fit. Brazed aluminum is used to make the core, which is 40mm thick. It also has polished aluminum end tanks that were TIG welded together.

A 40mm brazed aluminum core is used in the Classic mini Fletcher radiator. It also has polished aluminum end tanks that are TIG welded together, and they are polished. Replace the original radiator on your MINI Cooper S with an aluminum performance radiator made by fletcher. This will help improve the cooling capacity of your car by keeping the engine cool so that it doesn’t overheat, which will make it run better. For the same reason, it’s important to keep its engine at the right temperature, just like the fletcher radiator on the classic mini.
