If it is new to you...... transmission fluid level rear axle fluid level air pressure in the tires if it didn't drive onto your property, then spark, fuel and battery radiator level fuel pump filter (clean out and look at residue in glass) brake master cylinder level (need to remove the driver's door sill, floor mat and metal circle over top of master cylinder) brake light switch lights This will get you started in knowing your vehicle

Thanks nelsb, i have all those things on my list i just thought i would shake the shed for more ideas. will get the '51 prob. end of this week. my old '37 kept me busy but with all my health issues making it hard to keep maint. up on the old girl and hard to find a shop locally to work on '30s cars what i cant do any more. so i decided to step up a few model yrs to my birth year. my first car when i was 14 yrs old was a '51 chevy. i don remember it having a bypass oil filter like this '51 crestline victoria does. ive allready went to napa and oreillys for stuff.each of those oil filters are slightly different as in rubber gromments at each end and the wix from oreillys has two diff. size large canister lid gaskets.both of them listed for the '51. and car has been converted to 12volt. im sure i will have a lot more questions from the shoebox guys. thanks again for your help. Tom.

One oil that I found worked in my 1953 Ford Flathead was Pennzoil straight SAE 30 detergent API Service SN or later rating. Use of the above listed oil with Red Line Engine Oil Break-In Additive will protect your flat tappet valvetrain components. This additive contains the ZDDP additive package that is missing from modern oils. Modern vehicles have either roller tappets or roller finger follower valvetrains that don't require the zinc and phosphorus additives required by our older engines. Modern vehicles also employ catalytic converters to reduce exhaust emissions. The zinc and phosphorus additives can contaminate the catalysts so they have been eliminated from modern oils. You can purchase a Fram C4 oil filter from your local AutoZone auto parts store.

If the brake fluid is not DOT (silicone), I would flush the system. DOT 3 or 4 fluid goes bad over 5 years. Tom

there is probably controversy over whether the '51 239 takes 4 or 5qts with filter. Tom. This message was edited by same on 4-21-26 @ 3:48 PM

If you believe the dipstick and the tube it fits in are original to the engine and you are changing the oil filter with the oil, a safe bet would be to install 5 quarts of oil in the engine. Once you have done this, you can put a scribe mark on the dipstick so you will know when the crankcase is full.
