I have a 1989 FJ-62 with a small hole in the top of the radiator. I would like to replace the radiator on my own, but I am a little concerned about the time and expertise required. I would rank my mechanical skills as being average, but I have never undertaken such a project before. In general, what are the steps required to remove (do I have to remove the A/C component), what are the pitfalls of this project, should I replace anything else while this radiator is out, etc. Also, what is a good price for one of these units. I have been quoted $189.00 from radiatorbarn.com. Thanks.
