57Classic Posted October 16, 2023 Share Posted October 16, 2023 Hello again. I’m having a few problems with the car. For one, the radiator doesn’t clear the fan blades. (I’m pretty certain the radiator is for a later Chrysler, maybe a ‘35 or ‘36.) The one in it now has side braces that lead to nowhere on this car. Is it a better plan to try and source an original radiator? Also, I need to get the water pump off. Is it a good idea to use a puller to get the pulley off? There’s not much info in the shop manual. There’s a photo of the water pump (and damage) below. Link to comment Share on other sites More sharing options...
57Classic Posted October 16, 2023 Author Share Posted October 16, 2023 I noticed the tiny pin on the circular holder just in front of the pulley, so I tried knocking that out. It’s stuck, so I sprayed it with some lubricant. I’ll let it sit overnight and check tomorrow. Link to comment Share on other sites More sharing options...
ply33 Posted October 17, 2023 Share Posted October 17, 2023 I am not familiar with the Airflow, but for other applications the pulley (or on later water pumps a flange that holds the pulley) is actually pressed on to the shaft. Then the pulley and shaft are drilled and the pin driven in to make sure nothing comes loose. Point being that even if you could drive that pin out, you will probably need to put that water pump on to a bench press to get the pulley off. Way, way back when I had access to a machine shop with a fellow who was a good machinist and we went through the whole process of rebuilding one of these. Nowadays, without access to a full machine shop and machinist to help me I send the whole unit, including the pulley, off to a reputable rebuilder.. To remove the water pump itself, you should just be able to remove the nuts from the studs holding it to the block. Link to comment Share on other sites More sharing options...

Thanks for the advice! But I wish I could, the nuts at the bottom are impossible to access without taking the pulley off. I tried with a small wrench, but there’s no clearance. I don’t have any s wrenches to try, but I don’t think that will help either. Link to comment Share on other sites More sharing options...

I have several "special tools" that I rarely if ever use and can't be used for any normal application anymore. Link to comment Share on other sites More sharing options...
DFeeney Posted October 17, 2023 Share Posted October 17, 2023 Removing the front pulley is not "Rocket Science" Use the right puller and it comes off. Reach out to friends who have done this. It's part of the "Hobby" Link to comment Share on other sites More sharing options...
57Classic Posted October 23, 2023 Author Share Posted October 23, 2023 Good news, I got the water pump off. Bad news too, the impeller has a big piece broken off. Does anybody know a good water pump shop? Link to comment Share on other sites More sharing options...
57Classic Posted October 23, 2023 Author Share Posted October 23, 2023 I don’t recall the shaft being terrible, but corrosion in the block isn’t good. It’s not the worst either. I’m trying to search for a water pump rebuild kit, but to no avail. If anybody has a Chrysler Airflow water pump, do let me know! (I think they are the same across production from ‘34-‘37, but Airstream pumps are different.) Link to comment Share on other sites More sharing options...
