Robert Engle Posted September 15, 2021 Share Posted September 15, 2021 Olsen Gaskets Bob's automobilia for oil filter Will need to make your own bypass tubing for the oil cooler. I do not know of any replacement thermostats. There are people that restore the thermostats. Bob Engle Link to comment Share on other sites More sharing options...
michealbernal Posted September 15, 2021 Share Posted September 15, 2021 I think there was a posting on the form about a year ago on how one of the members fixed his malfunctioning thermostat. You might check it out. Link to comment Share on other sites More sharing options...
Mark Shaw Posted September 16, 2021 Share Posted September 16, 2021 From an earlier post on this forum: Buick Thermostat Bellows Repair These are fairly easy to repair. Perform an air leak-down test using 5-10 pounds of air. If necessary, solder the repair which is usually a crack in the bellows section. When disassembled, use bright light against the suspected section to see the leak area. After soldering together, fill the unit half way (and I mean only half way) with Methyl Alcohol using the "soldered over" fill area in the rear of the unit. You can also replace the soldered fill hole with a machine screw and nylon washer with sealant. Using the machine screw method also makes it easier to perform the leak-down test. Methyl Alcohol is used in some brands of Dry Gas products, so read the labels carefully. I found mine at a local Rite Aid drug store. Do not use Ethyl or Isopropel alcohol. Test the unit in a pot of boiling water before reinstalling. Cost of Solder: $2.50 Cost of Dry Gas: $2.99 Repairing it yourself: Priceless! 1 Link to comment Share on other sites More sharing options...

Bob Engle Hi all, just a quick note, I put in an order for an oil filter with Bob's for my 1930 Buick a couple of weeks back, he told me he has none in stock and has to look for another manufacturer.
