Thread: I could use some help removing air pockets from my coolant system (waterpump change)

Tweet

Ok guys so heres what has lead to this. I have 2 radiators in my 41 willys pickup, a small one up front and a large one out back in the bed. The regular GM waterpump just wasnt doing it's job with the amount of coolant in the system, in traffic the temps would creep. So I went and ordered a high flow pump from Flowkooler. I got it on today and topped off the coolant through the waterpump heater port on top so that it would fill the block. I took it out for a test drive and it got to 200 quickly and never came down, then crept up a bit as I parked it. The truck regulary ran around 185 in cruising conditions before, so I'm guessing that I have air trapped in the system.

Ive seen guys run the engine with the cap off of the radiator but due to the large amount of coolant in this system, and the way the radiator is angled it will be hard to keep up with whats going on in there. I have a cap on top of my intake manifold right above the thermostat, can I just bleed the system that way? I will post pictures of the radiator and the said cap on the manifold below.

Thanks in advance!

and the radiator way in the back, its hard to tell but its mounted on a slant:
