Should I trade this in
My impala is starting to act up,last month starter went ,then I noticed antifreeze was a little lower each day water pump is going ... Now a oil pressure is low stop car now ,changed the sensor now it's worse than before it was fixed won't stop going off dealer has no clue checked air filter everything is tight looked for oil in the antifreeze can the water pump just starting to go cause the oil pressure to drop or is there some other cause !!!
