Re: [diesel_mercedes] RE: California temp/coolant?

 

Thanks Nate, filled her up with coolant and on the coast down she gets to about 85C, so she's a happy camper!

Well Bud ;

100° C isn't terribly hot depending ~ if you're tooling an S Klasse along @ 85 MPH over the grapevine and it cools off to 85° C coasint down the other eisde I'd say fill it with coolant and relax .

If the temp. remains above 90° C coasting , you have a serious problem ~ I bet there's scale in the water jacket , distilled water creates rust like tap water just slower .

So , judge by the coasting temperature and either clean it more or simply put in properly mixed coolant .

I agree with Brain ~ M-B branded coolant is cheaper in the long ruin and usually easy to find in So. Cal. if you look .

I've flushed out my 1979 300SD, changed the thermosta(it was shot) and just have distilled water in it. It runs a tick over 80C around town and about 95C on the highway(up and down some slight grades-about 90C level hwy).
Going up some standard grades (Newhall Pass- a few miles) it's running a tick over 100C. Before I attempt something like the Grapevine(I-5) I just wanted to run the temps by the group.
I'll be putting Zerex G-05 in tomorrow. There really was no rust or scale buildup. The engine was rebuilt about 100k ago as told to me by the previous owner. Everything I've done so far has revealed that it was rebuilt.
I've got a diesel VW, so I always keep an eye on the temp. Just haven't run the 300SD to know what normal is.
Thanks,
Bud
