Mix Dexacool with green antifreeze?

[JSAautomotive]

From what I have read last year, some automotive techs that are professional engineers and expert witnesses said that the stuff is not good for as long as claimed. Sort of what you talk about with regard to advertising claims, but that it is a fine product, just not a 5 year/100,000 mile substance.

Exactly. But the difference between the old style Prestone and the Dex-cool is, if Dex-Cool is allowed to get low in Ph, it starts eating things whereas the Prestone won't. It'll just loose it's anti-freeze/anti-boil properties.

Funny thing about dealer mechanics, everyone I know says they work on junk and the one's I know that have changed shops to work on a different MFR's car all start off with feeling happy about better cars but soon fall back to (insert any mfr) car's are junk.

I think the cars are being better built for the most part. Hence for the slowdown in the maintanance market. Some of the systems are more logically built and more modular (whole componant replaced vs. individual parts). But part of the problem (i.e. bad attitude) with working for dealerships is getting paid a third of your regular pay (flag hours) to fix their warranty work. Tell me what job out there tells you, "well.... see that work over there?? We're going to pay you $15 an hour to do that work. But this work over here, we're only going to pay you $5 an hour to do" (the same exact type of work). Then add in how they cut corners to save a few cents here and there. Example.... the old Delcotron alternators we're built with a failure margin of 2 I think it is (by electronics standards). Nowadays the late model CS alternators and their counterparts are built with a failure margin of 1 or 0, which means the discreet componants are not as heavy duty as what was used in the older Delcotron alternators and higher failure rates. Anyone that works with late model Fords can tell you, their alternators are junk. You basically have to do certain mods in order for them to live when rebuilding them.

But I've had my share of "so-called" engineers when I used to work at dealerships.

If we had a problem child car and the dealership didn't want to pay me my diagnostic time to fix a factory F'up, they'd send a Rep that was supposed to check my work/verify the diagnosis. When they'd show up I'd just basically just tell him..... "well... there's the car.... have at it!!". The guy would look at me like I was going to tell him what the problem and diagnosis was and lose my diagnostic time. He'd spend the day on it and then leave without a word. Next thing my service mgr would come up and say, "ok John.... you win. Fix the car and we'll pay you straight clock time". Cheap bastards...... wouldn't even pay me what I was worth to fix their F'ups.

Now you know why I left the dealership venue. Along with the politics.... it just makes for a B.S. work enviroment.
