My 1987 manual supra turbo that has 60,000 miles. I am looking to replace the timing belt as part of maintain. I got a quote from the dealership $390 plus tax to replace all four belts. Should I replace the water pump and any other items while it is apart. I am due for a antifreeze flush I guess this would be a good time to take care of this. Does anyone know of any shops in the Central NJ Somerset County area that work on toyotas/supra? Thanks
