cooling a hot 428

[fairlanegt427]

after many attempts to cool down my 428. I think I finally got the problem fixed. after spending about 1500 bucks figuring out cooling problem with new radiator many different fans etc etc it came out to be that I had a broken magnet In my meziere water pump.  that cost me 120 bucks to get figured out.  that is a good place to start if you have cooling problems with an electric water pump.  the guys at meziere were very good to work with. just food for thought.

So, was the pump not turning at all, or turning at a reduced speed, or?  Sounds like a difficult problem to diagnose; glad you found it.

With a broken magnet, I'm guessing it was turning at a reduced speed...and fighting itself the whole time. Very surprised that it didn't burn the motor up. And yeah, that would be a tough one to diagnose unless the motor was getting really hot. Sorry it cost you so much to find out

it was a pain in the butt trying to find the problem. I even pulled heads thinking that I put head gaskets on backwards. I know I didn't but when things like this happen you start to question yourself.  but any way I was looking in radiator and stuck my finger in and you just didn't feel any water pressure pushing against finger and or very very little.  so I sent in pump,  it was the last piece of puzzle and thank god it was the problem.  yeah I know I spent money but it was towards the better just to upgrade the whole cooling system.
