- Buick Ownership
Shop ended up replacing CPS and the HB as it was cracked. Yet, the tachometer briefly went out yesterday. Code 56 is gone. Now I still have the SC pulley squeal on start up. Heater core seeems to be leaking since passenger carpet under dash is quite damp. Coolant tank empty. Oil level fine. ATF lines leaking near the ATF cooler. No more shops!! Could be just time to sell it on Craigslist. Somebody with skills beyond mine might keep it going supposedly the engine should be good after they changed the gaskets but I am not sure of what they did? Wires are running in places not there before? Time for a new Buick? Toyota?FSM Field Service Manual or Full Service Manual.
