They used the plastic tipped sensors untill 2000-2001 in the S model saturns. In 1996 S model saturns they went from two coolant sensor to one so you have one sensor. The sensors are only 10-11 so there cheap just to change as maintance item. It very well could have a plastic tipped sensor in it. Also make sure the connector going to it that the terminals arent blue or green instead of silver meaning there corroded. Other wise you will have to replace the connector as well. As far as the timing belt all the S model saturn engines use a timing chain. So if the chain isnt making noise then there is no need to replace the chain. My 1999 SL2 has 226,000 miles in it and the chain is still isnt making noise.
