Hi yall..Jim from Sterling, Va. I posted this in a topic it didn't really fit in, so I'll start a new one..

Ok, you guys, no laughing at the newbie (uhm, that would be me). Jeez, until I started reading here a few weeks ago, I thought I knew a thing or three about maintaining a car. You doods have forgotten more than I ever knew.

Ok, it's a 92 Hyundai Elantra (rebranded Mitsu), 1.6L. Guy I bought it from didn't know about timing belts and it gave way at 89K. He put a new engine/5 spd. transmission in it, sold it to me for $1275 because he'd put enough into it. So, ever since, it's had Mobil 1, 10/40 Summer and Winter, until the last year or two when 0W-40 came out, which I use December-March. Car has never been crashed, has run great, and now has 238,000 (almost 150K on the engine) miles on it. I used to use Fram filters until last week, when thanks to you guys, I spent the extra buck or two for a Pure1 from Puro. Who knew Fram used cardboard inside???

Reading here has challenged some of my assumptions about how I've maintained it, however. For instance, for awhile, they (you know, THEY?)talked about extended-life coolants (Dex-Cool) not clogging the radiator with silicate, and I've used it to (what I thought was) great effect, in that the inside of the radiator and water pumps I've had replaced at timing belt-time are like brand new inside. Here, I've read that Dex-cool isn't so hot after all.

Dura-Lube every thirty thousand. Ok, ok, so I got hooked by the infomercials Pat Goss used to do. They ran an engine that had been Dura-lubed dry of oil for a half hour or some such with no oil, and the thing kept running. Obviously, Pat said, don't try this at home, but now I read here that other than Mystery Oil and some random FI cleaners, who needs Dura-lube or Slick? The rest of the work this car has has needed has been brake pads, tires, exhaust, corrosion-control, stuff like that. It gets around 35MPG HWY, no AC, a little less with the AC, and seems to do 85 all day long between here and Fla., and Massachusetts without even breathing hard. It burns no oil, and tests against particulate and CO comparable to a 2002 Elantra.

Nonetheless, with all this, I must have been doing something right, but is there something I should be doing different with the cooling system? I should add that I have them replace the water pump at the belt change just because, not because one ever failed. I gather the 0W-40 is a good move, and I change it every 3,000 miles. I know it COULD go longer, but it's so dirty by 2,500, I can't bear to leave it in there. It needs a half-quart or less between changes to keep it full. Also, I'd SWEAR the thing runs smoother after I change it. This is a car I know every vibe, in and out, and it FEELS smoother. Or am I high?

I'm off to test my new Mystery Oil I added (12 oz to 12 gallons of gas). Appreciate you guys, I've never seen such a body of work anywhere before I found BITOG, as you refer to him. Proof positive, the best work is for love rather than money! Thanks for any accumulated wisdom yall have to offer regarding this heap.

Merry Christmas!
 
The coolant questions also interests me. I recently did a coolant flush using Toyota Longlife red coolant. I have heard, but am not sure whether or not it is factual, that the red Toyota coolant is the same as the Dex-cool, just a different color. Any commments? Sorry toocrazy, not trying to hi-jack your thread, just thought the questions are very related.
 
No, man, that's ok, it's all relavent. I had an 86 Toyota pickup that had red coolant brand new, and the guy I bought this car from told me the coolant was red when he bought it, but every time I've taken it in for the timing belt/water pump (twice since I bought it), they return it with green. And then I flush it until it's clear, and re-install new DexCool. I can't remember where or who, or even if it was here at BITOG, but I was reading some very derogatory things about it. I don't leave it in for five years, I change it every year, sometimes, twice. A year ago I did the timing belt, and then flushed the dealer-green out of it, and replaced that with DexCool.

A couple of weeks ago, my thermostat went full open, the car wouldn't warm up, and when I replaced the thermo, I installed new DexCool, again, just because. I figure once a fluid has been out of the vehicle, I don't really want to put it back. I have no factual basis for that compulsion, it was clean and good to like 30 below or some such, but the replacement, it's just an instinct. Maybe I'm just paranoid?

Thanks, Buck-oe!
 
At the risk of hurting your feelings, I'll be blunt and call you a little paranoid. Changing the coolant more often than once a year is a waste of resources (your wallet and the planet). So is changing out synthetic oil at 3K.

Don't fret - there are lots of people that have come to this board for help on breaking their compulsive behavior. Get another car, or two, for hands itching to wrench. That's what I've done.

If you recently switched to synthetic oil, your engine may be experiencing a cleaning effect from the new oil.

Personally I'm a big proponent of Zerex G-05 antifreeze. I see no reason to stock anything else in my garage.
 
Hiya, Kestas..

No, well, actually, the coolant has been changed twice this last year and a half out of repair circumstances. Once a year IS excessive, if the system doesn't have to be opened up for thermostats or water pumps. As for synthetic, the Hyundai dealer replaced the engine/transaxle new (refurbed?) out of the crate in summer of 97. When I bought it from the original owner, it was on the first fill and it's seen nothing but 10W-40 Summer/0W-40 Winter Mobil 1 changes every 3000 since (excepting of course for the Dura-lube every 30K, which may or may not have been beneficial from what I read here). As for the oil at 3000, man, it looks so filthy by that point, could it be that the Frams I've been using suck so bad they don't collect it all (I'm on a Pure 1 right now), or would a bypass system keep it cleaner? The thought of that nasty crap running through the engine makes me...well, PARANOID!

Is the G05 green, or red? Do you need to flush the DexCool completely out when you do G-05? Does it have silicate? Or is THAT concern overblown?

Thanks Kestas!

oil color means nothing...

I'm quite sure your car can push 10,000 miles on Mobil 1 or atleast 7500.

If you like changing it so often at 3000, you might as well use a high quality conventional oil like havoline.
 
zerex G-05 is the stuff that ford and chrysler are using as their long life coolants. i know it used to be available at autozone, but i havent checked lately. i bought a gallon to have about a year and a half ago for my 04 neon. it seems to be good stuff, the factory fill coolant in my neon looks just like new after 40000 miles. you would want to flush completely before adding G-05 to you system. i do not believe any coolant should be mixed, except for the universal stuff. but im still not too sure about that. i asked prestone about how it would do in a 98 beetle and they said it would mix fine with the G-12 that is in it. (dont worry about using G-12, it really expensive and you dont need it. $18/gal from an audi/vw dealer) i am using a universal in the beetle now and now that the fans actually work when they are supposed to it has no problems.
 
I would double your OCI. I'd bet your engine is spotless, oil and coolant passages.

FWIW I drop whatever is in the radiator (I don't do the block drains) every 12 months. It dosen't clear the whole system, but it sure does take care of a large portion.
 
toocrazy2yoo,

It's good that you changed your coolant back to what it's suppose to be. I know for sure that you're not suppose to mix different coolant colors (unless it's blue mixed w/ green, as in a Honda). I believe that if you mix, say a green/blue w/ a red/orange it can seriously affect it's cooling abilities at high temps. I also heard that if high temps are reached with the coolant colors mixed like that, it can form sort of a gel or something inside your engine, causing it to quickly overheat.
 
Hi,
I agree with the above posting - bad things can happen when "organic" is mixed with "non-organic" antifreeze. I confess I don't know which is which by the color of the stuff. Is red organic or non-organic? I don't know. But apparently there is some sort of reaction that can take place which can clog your entire cooling system.
This was a problem (I understand) on some GM vehicles that suddenly switched over. Everything was great until an uninformed owner or mechinc tried mixing the colors. Then bad things happpened.
My wife and I just bought a 2005 Honda CR-V. It has been a source of frustration and disappointment for us that virtually every fluid in this car is some sort of proprietary concoction. Honda refuses to assist us by naming acceptable alternatives to their fluids. And as we all know, Trial and Error is an extremely expensive way to learn if blue is compatible with green, or Honda brake fluid is compatible with Prestone, etc.

G-05 is yellow.

I wouldn't mix coolants. I've seen coolants in auto parts stores that say "mixes with any coolant". So does hydrochloric acid.

The G-48 that goes in one of my cars and my motorcycle is dark blue. I'm told that mixing non g-48 with g-48 causes gelling and other bad results.
 
Thanks one and all.
Well, maybe I'll go to the Xerex G-05 next time, after a thorough flush. I've never been one to mix this stuff. The Dex Cool certainly hasn't HURT anything, when Hyundai did the last water pump (I have them change it at every timing belt change) the guy told me it was clean as a whistle (this place actually lets you talk to the guy who does the work. I like that). They changed out the valve cover gasket for me, no charge, also, and he said it was as new inside as when HE put the engine in in 97. They seem to take pride that one of their own is on the road for so long. Not the salesmen, of course, they're always trying to sell me the loaner, always new, ready to deliver to me, the sucker, hehe. Don't like the new ones much.

So, if to save money, I go to a conventional oil for my OCI of 3000 (I have to face it, I am a clean addict, I can't bear to have the filth running through the engine), what's an alternative to Mobil 1 10W-40 Summer, 0W-40 Winter? Cool thing about the 0W-40 is I get NO lifter tap at startup no matter HOW cold outside. I tried conventional motor oil once or twice, but that **** tapping at startup always drove me back to Mobil 1. Still, it's been a couple of years, maybe the conventional oil is better now? Or is it possible my Fram filters were letting the oil drain out giving me semi-dry starts? I'm on a Pure 1 with this latest oil change.

Again, thanks, all.
 
In summer it does. In times of temp ranges up in the 90's, they call for 20W-50. This is a 1992, remember. Of course, back then, 10W was as low as it goes for the winter. I suppose 5W and 0W oils weren't even in the stores then.

Tx for the tip!
 
well I know for sure the 20w50 and 10w40 weights of havoline can handle the abuse a motorcycle dishes out, and I'm pretty sure your car is easier on the oil.

Either go dino for short OCI's or stick with a quality synthetic like mobil 1 for longer OCI's...

and to set your mind at ease on how long your oil can last do an oil analysis, it'll tell you a lot about your engine.
 
Thought about that, I've seen it mentioned. I wouldn't have a clue what the numbers meant, though. Is there someone in the area that does it? Garages? Labs? Or is it a mail order thing?

Thanx, Dood!
 
I don't think it was excessive of you to put new coolant in there when doing a repair. I would however take that into account when figuring out when to do it again.
 
Well, I did it in November when I changed the thermostat. I caught the "old" (1 year) coolant in a tub, but there was debris, minor, but there, from running over a ledge under the drain valve on the radiator. I just figured once the stuff has seen the air and a little filth, I might as well change it. Next fall, I'll change it again. By then it'll be ready for new hoses anyway. When I do those, I'll change out to the Zerex G-05. THAT I'll leave in, well, for a year or so, as the timing belt will need changing!

eeesh!

Thanks!
 
kanling,
Can I substiute the TOYOTA RED into my 96 Buick 3800 Series 2? I have Dexcool in there now and I am looking to change it out.
