Antifreeze/Coolant Change Intervals

[Ralph Spears]

I think ZEREX came in the yellow or gold can, I think the anti-freeze went to plastic jugs when the motor oil also went from cans to plastic bottles

And I thought I was over the top. I salute you my friend To your point Jake, it is cheap insurance. FWIW, coolant can get an electrical charge to it (aluminum, poor grounds, etc.) That will raise hell with both the radiator and the heater core, to say nothing for everything else!

I also change brake fluid every 5 years (or sooner)

I’ve never used a add on water pump lube, but I’ve seen it

Do you bleed the brakes too or just remove brake fluid from master cylinder and refill?

Not sure what Tim does but on the old cars I've been using a turkey baster to suction out the fluid in the master and just refill it every year. On the daily's I take to Brad and have him flush every 4-5 years.

I'll suck the fluid out of the master reservoir, replace it with fresh fluid, and then just do a gravity bleed. It's about a 3 beer event

And when the job is done...go for a ride...and then make an appearance at the Boulder Beer Bar

I went to Dot 5, it’s been in there 24 years. Wonder if that needs a flush.
