Can't find Zerex G05, only alternative MB coolant?
 

AutoZone used to carry the Zerex G05 coolant which is OK for the MB cooling systems, however now the stuff can't be found. Is MB coolant my only alternative? Thanks

Try Pep Boys; I had same problem at advance and autozone

NAPA also.

I got mine at NAPA...right on the shelf.

Very easy to find here in Seattle. Napa and Carquest. Carquest is very good for Mercedes parts since they are connected to Worldpac. They have all the special fluids.

I've always bought it at NAPA.....recently the price even went down about $2. I was quite pleased!

honeslty, whats the big deal with Zerex, i have never used it in any of my cars and they all have never had a problem with the Prestone i run.


maybe i have been misinformed?

We are talking G05 here... G05!

Spending more than 10 minutes looking for it is too much for the couple dollar savings you'll get. Grab the MB bottle and move on to something else.

That works if there's a dealer near you, in my case it would add over 2hours to the project.

Couple Dollar? More like $15! Dealer wants $25+ a gallon, NAPA charges $11.59 or so for G-05. I'd drive 30 miles to get it! (thankfully its only 1.5 miles away though :D)

i know, but whats the difference between it and what im running right now. performance wise and durability wise.

I don't remember when I got my last bottle, but it was maybe 2-3 years ago and nobody local stocked the Zerex. Turns out the dealer's price was somewhere in the teens, which wasn't too bad.
Either way, spending an hour of my time and $5 on fuel plus wear and tear to save $12 still sounds inefficient and knauserig to me.

You are kidding, right? The standard green coolant - or any coolant not approved for use in an mbz engine for that matter - does not adequately protect the aluminum parts from corrosion. Do a search - there are accounts out there of pieces such as cylinder heads and blocks which were removed and then examined. Sharp edges adn mating surfaces were rounded, and other evidence of corrosion throughout the cooling system. I know on my 300E the PO used green coolant and the pump fins were all rounded and corroded when I removed it. I promptly switched to Zerex G-05 and hoped for the best. Fortunately the head gasket never gave way.

Bottom line is: green coolant in Mercedes = BAD

Using prestone (green) over 32 years. in my 77 450sl. Replaced one water pump in that time. (replace prestone every 5 years)This is an ongiing discussion,suggest that water content is critival factor. If local water is reasonably free of minerals, no problems.If heavy mineral content no antifreeze is fool proof. Just my 2 cents. Good luck all,Abe G
