Compare BMW 4 Series radiator repair quotes from specialist garages

Looming hundreds of feet up in Munich's skyline is BMW's headquarters, a vast and impressive building designed to look like four engine cylinders - the configuration that drove much of the brand's early success.

BMW has come a long way since 1927, when it produced its first car, the Dixi, shortly to be renamed the BMW 3/15. In 2022, it was awarded 'Best Manufacturer' at the AutoCar Britain's Best Car Awards, and the same year, it triumphed at the WhatCar? Awards, winning more accolades than any other brand. The M5 special edition, celebrating 20 years of BMW motorsport, is one of the rarest M automobiles in the world.

Car radiators help to get rid of excess heat in internal combustion engines. They consist of two water tanks linked by several narrow tubes. The hot coolant is pumped from the engine through one tank and the core, and cold air is used to reduce its temperature so it can be pumped back into the engine.

Common car radiator problems include rust, leaking coolant, damaged fins, a failed radiator fan and a broken water pump. Watch out for the following symptoms: high engine temperature, coolant colour change, low coolant, sludge in the system and visible damage. All these issues indicate you may need to book a car radiator repair.

There are a few different types of repair to be aware of, such as car radiator hose repair, car radiator refurbishment and coolant leak repair. The cost to repair a car radiator varies depending on which car you have.
