Hey guys. It's come time for me to change my coolant in my '96 Deville at 150k+. I have been researching about using the coolant tablets, however, I am finding conflicting stories. Am I to use the coolant sealant tablets or not?
On a side note, I have a problem with the oil level warning on the dash when the oil level is fine. Also, the oil pressure light flashes sometimes at idle. Any ideas on these? Anybody know where to get the oil level sensor for a good price?
