Hi guys.. This is my first question on here so go easy on me.. I have several old chevy cars and trucks from the 1960's and 70's and im real big on maintenance with my "collector" vehicles. my question is does anyone see it beneficial to switch over to the zerez G-05 formula. It seems like in the last few years the only thing i can find is the mix with any color stuff around here besides the g05. Ive heard the G-05 is far superior but does anyone see any issues switching over in an older engine? These vehicles are driven mostly in the summer months and i put maybe a 1000-2000 miles on each one a year. any info will be appreciated.
need some coolant advise

I'd stick with the standard green stuff. If you have a pep Boys,Autozone,CSK/O-riley or Napa around they will have the old green.
It's been my experiance that the long life coolants don't protect copper and brass radiators at all. The new coolants are designed to protect aluminum radiators.

+1 But, I don't see any issues with switching to G-05, but you should do a total flush. Wouldn't hurt depending on time on the present coolant to do it with the green. JMO

thanks for the replys guys.. all of my All of my vehicles have had the radiators replaced during restoration. When looking down the water neck of my 77 chevy truck i notice a substance forming on the cores in the rad. Im assuming this replacement rad is aluminum and was a little ticked because i paid alot for it. thats why i was thinking the G-05?? I should have mentioned these are replacement radiators in my initial post.
What are you using for water to mix with your coolant?
distilled water. deinoized water is really not available to me
Distilled will work just fine.
Check the clutch for the clutch fan by trying to spin the fan when you shut off the engine after running it on a hot day. If you can spin the fan the clutch is worn out.
These clutches have brake shoe like material in them and they wear out. One of the best things you can do for these type of vehicles is to replace the clutch for the fan.
If you are going to tow, or want extra good air-conditioning, use a heavy duty clutch, but expect the fan to roar (it will be noisier).
You do not have to remove the belts, but put several sheets of cardboard between the radiator and fan to protect the radiator from being bumped by the fan when you do this job. I usually replace the nuts, and sometimes the studs. I also use high temperature Loctite on the bolts that go into the clutch and on the studs and nuts.
Loctite is one of the best tools anyone who works on cars should have. Basically any nut/bolt put together with Loctite will not come apart from vibration and thermal cycling, but will require the same amount of torque to loosen it that was used to tighten it.

What color is the accumulation in the core?
