Some general maintenance
As with any older vehicle I purchase, I start off with some general preventative maintenance.
I switched to full synthetic Mobile 1. I decided to try the "high milage" stuff, being a little worried about switching to synthetic causing new leaks.The engine seems to like it so far over the past 700 miles.
I noticed that the coolant temp was a little be all over the place, so I replaced the thermostat. It seems to have helped a bit, but I think some fresh coolant is in order.
The in dash oil pressure gauge was a little sporadic, pegging to full pressure for a half a second then dropping back to normal. I swapped out the oil pressure sensor which fixed the problem.
I noticed a bit of smoke coming out of the oil fill tube, so I replaced the PCV value hoping that there isn't any other major issues causing the smoke.
I read that these Astros go through fuel filters as fast as oil filters, so I replaced mine. The old one didn't look too bad, but it was cheap.
I also installed a tach. I've never driven an Astro, or anything that weighed this much, so it was hard for me to tell how hard I was pushing it going over the passes we have here in Colorado. The install was super easy, there's already a single wire ready for a tach.
