Had problems with Mulfab. Bought new Mulfab ali rad through Richard Thorne, failed within two years due to faulty welds, sent back, replacement / repair leaked after use within 100 miles. Mulfab said we needed to take the car to them. Drove up ( 300 mile round trip ) Guess what 18 months later leaks from welds, Ali too thin at weld.Have to say original with car no problems for 9 years and 24,000 miles.Model is Plus four, 2l Rover year 2000.To say the least no very impressed with Mulfab. Will try to go elsewhere to solve this long term problem.
