How do you know when it’s time to flush coolant? Technicians may have different views on the subject, but Dorman Training Center instructor Pete Meier explains how using a test strip at every service is a surefire way to get an accurate picture of the coolant’s health.
I don’t own a bearing race driver kit, and I haven’t in 20 years of fixing stuff. I also refuse to use sockets to drive a race. I learned a method a long time ago I’ll pass along to you newer techs: I use the race I’m replacing. I primarily have used this trick when servicing trailers, but there are plenty of late model Ford E-series vans and old 2WD trucks still prowling around that need the odd wheel bearing here and there.
It takes longer to write down the steps than it does to just do the job. Use your punch and drive the old race out; this is going to become your tool. Get the new one started somewhat evenly; a scrap of lumber is perfect for this. Sink it flush with the bearing pocket. Grab your old race and some PPE and cut a slice through it with your whizzy wheel. Drive your new race with that. Here’s a good demonstration:
I’d suggest doing just one thing differently. Stack your old race opposite to the way you see here, so the thick side of the old race is butted up against the thin side of the new race. Use that to tap the new race all the way home. If you do it in this manner, you can just grab the punch that’s still laying there from removing the old race and on this go ‘round, due to the slice, one tap sends it back out the way it came in.
Save some money, save your poor sockets, and save some space in your toolbox.

Technicians discuss battery testing, one says open circuit voltage of less than 10.5 volts indicates a bad battery, while the other says that a reading of 12.5 volts indicates an 80% state of charge. Who is correct?
