Common Problems This Radiator Can Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted or inefficient heat transfer
• Transmission fluid temperature issues related to a failing cooler circuit
• Reduced cooling performance from internal corrosion or tube failure
• Fitment issues from a damaged or previously repaired radiator assembly

Installation Notes and Tips

Confirm radiator dimensions, inlet and outlet sizing, and cooler layout before installation on your Mercedes-Benz SLK250. Transfer any required components from the original assembly only when needed, and inspect hoses, clamps, and mounting points for wear before final assembly. Proper system flushing and refill procedures help protect the new radiator and cooling system.

Quality Assurance

OSC tests the radiator core before assembly, then tests the transmission and engine oil cooler circuits prior to tank installation, and performs a final pressure test after assembly. This multi-stage process supports consistent fit and leak control for Part Number 13213.
