I am stuck here at work and I need a little help. I am replacing the waterpump and all the sensors while the 20+ year old cooling system is open and some of the parts I have recieved from my vendor appear wrong. I already have the correct:
..waterpump
..t-stat
..rad. coolant temp/fan sw
..gague sensor

Need parts number for 1982 928 m28/11 cis motor

1. bushing for the coolant bridge, the internal one that the base of the T-stat seals against
2. thermo-time switch

Also are there any other sensors That i should replace for the cooling system, Thanks in advance, DAVID
