I have a 2013 hyundai elantra. Has 31,600 miles. Dealer recommended having radiator flushed and filled. What is your opinion?
Can't hurt, but modern cars are designed to go 50,000 + miles without coolant change unless there is a leak or something.
I wouldn't. I bought my '93 Chevrolet Caprice brand new. Every 2 years, as recommended by Chevrolet, I had the cooling system flushed at the dealer. In the 19 years I owned it I went through 3 radiators, 3 sets of hoses, 2 thermostats, and 2 intake manifold gaskets. When I sold the car in 2012 it was the intake manifold gasket was leaking, again!! Unless I'm having a cooling system issue I'll never flush a cooling system again!! HTH. -Jim
