I have a 94 ls400 with 226k on it. I bought a good kit that has a timing belt waterpump,gaskets, 2 idler pulleys, and tensioner. I paid 260.00 for it at a part store and I got a great deal cause he said it wouldve cost 450 without the discount. I have a good mechanic that said.he would do the job for 325 and I called a few places and some were saying labor 425-600. So ill be going with my mechanic and total cost plus coolant would be about 600-650.
