How is replacement of radiator done?

if anyone has told you this RUN, it is in front of your car less than two hours to replace

No. It's not a simple repair but will take 2.5 hours per Mitchell for a skilled trained professional with the proper tools and knowledge. Personally I wouldn't try this one myself at home and I have been an ASE certified master tech for 32 years. Without a hoist and special tools to disconnect the cooling lines it may be impossible. If you would like us to do it just call me and schedule an appointment (313-562-7022). Larry
