Planning on driving my 93 mini van from NY to FL it has 150 k miles on the clock. I rebuilt my transmission four months ago replaced alternator also thinking of replacing the water pump is there any thing else I should be concerned about. I have only had this van about a year I am not sure what’s known to go wrong with this van. It has the 3.3 motor I herd a knocking sound form the engine but it went away.
