I discovered that my 1950 Hudson Commodore 8 has no thermostat in it, and I am a bit confused as to which one is correct for the car? There are a number of them on eBay, but I am unsure which one is correct. Any help would be appreciated!
Secondly, I changed the oil in my car and feel certain I only put in 7 quarts, but the engine registers a quart over. I admit I did not check the dipstick until a couple of days later. Could it perhaps have the wrong dipstick? How long should the eight cylinder dipstick be?
