Re: Removing the Radiator on 1935 Eight
Posted by Owen_Dyneto On 2015/3/14 14:25:07
I can't help you with the radiator removal as the 35 senior cars are completely different from 1934 and back where you must remove the radiator, shell and shutters as a single assembly. Hopefully you'll get some advice from someone familiar with the 35-36 seniors.
But in addition to the water pump and radiator as possible contributors to your overheating, I very strongly suggest you add the water jacket side plate (water distribution manifold contained therein) to the list. In addition to whatever the needs of the jacket and distribution manifold may have, removing it will allow you nearly complete access to the internal water jacket, especially the narrow passages between cylinders which are essential for the cooled water to reach the exhaust valve seats - an excellent opportunity to do a thorough cleaning. New jacket side plates are available should you need one.
Engine shown is a 34; 35 essentially the same except that the oil cooler does not mount on the water jacket side plate.
The water pump is so simple that there really is no need to have a professional rebuild it as long as the shaft and impeller are OK. The two bearings are everyday common, as are the seals, though you might want to get sealed bearings and not have to worry about the oiler. And the graphited packing is available in original split rings or continuous cord from most any plumbing supply house. The copper ring gasket is also commonly available. The most important thing is to minimize the clearance between the back of the impeller and the block; double the clearance and pump efficiency can drop by as much as 4X.
