So my car was serviced at 48,000 back in 2006. It just turned 86,000. I have flushed it once when I installed an Koyo radiator. I'll be getting my TB service this coming Jan. due to years only. Since it has only 38,000 miles on the pump and likey to have only 40k in Jan, is it really necessary to replace the WP. Timing cover still looks new so I may kill that too. Everything else gets replaced. I'm not being cheap but seriously, does a 40k pump really need replacing? Thanks for any constructive criticism in advance.
