1999 SL1
Default Saturn SL1 Overheating Problem

Hi, my Saturn SL1 (1999) is overheating, the radiator fun is working (at least It turns on when I force it to do it turning on the A/C) by the way I swapped the 2 relays so A/C relay must be working, I just changed the ECTS and when car's temperature reaches 1/4 in the meter I can see very little bubbles in the coolant liquid container ( I hope it means that the thermostat and water pump are working ) I hope !!
all liquids and oil in good levels and no leaks, any clue what alse clould be the problem ??
I see that lots of users are having exactly the same problem (seems to be a bad design issue) but I can not see any happy solved problem
Thank You !!

REWARD EXCELLENCE!

Is it boiling out the cap or getting hot according to the gauge? Reading by the 1/4 mark isn't even close to overheating. When functioning correctly, the fan should activate halfway between 1/2 and 3/4, if it's doing that there is nothing wrong.

1999 SL1
Default Re: Saturn SL1 Overheating Problem

It's getting hot according to the gauge but when I mean hot I mean 3/4 and still going up but I stop when it gets to 3/4 to avoid a big problem,
When I mentioned that the very little bubbles inside the coolant container start after 1/4 it was just to explain that the water pump seems to be pumping and I guess also the thermostat (I hope it)
But the bubbles are very tiny and inside of the container, not boiling out

And my concern it's because the car never had done that before, no matter the extre weather conditions, no matter how far I drove before, it had never came even close to 1/2 on the gauge before, and now it gets hot really fast
(15 minutes in normal traffic and it reaches 3/4 and still going up
when I stop and check the radiator fan its working, coolant level is ok, oil engine level is perfect

What else could it be ?

When you opened your coolant reservior, did you happen to notice either doo-doo brown or perhaps a chocolate milkshake? If the former, I'd flush out the coolant and put fresh coolant in. If the later, chances are the head is cracked.

Default Re: Saturn SL1 Overheating Problem

The color of the colant is almost transparent brown and as dense as water (I think that may be normal) and because levels are OK guess there are no leaks either
The thing is I don't know hot to flush out the coolant, how do I do it ?
and what is a head is cracked ??
Do you guys know if the SL1 (99) has a radiator cap,?, if it has it I don't see it anywhere
Thank you

Radiator cap on a Saturn is basically where the reservior is. There is no actual cap on the radiator.

Cracked head means where the engine has cracked the head somewhere, and is putting oil into the coolant, causing massive overheating.

sounds liike a cracked head. the air bubbles are engine compression in the the water. the coolant will become milky & brownish if so. check the oil for sludge in the oil on the dipstick.. if ya don't see anything wrong with the fluids maybe the problem just started & it's in it's early stages and you will shortly...

the single cam engines are famous for this...

1999 SL1
Default Re: Saturn SL1 Overheating Problem

Thanks for all your help
I just checked the reservior again with the gauge in more than 1/4 of tempterature and I don't see the tiny bubbles again and actually when I saw them it was only for the first 2 or 3 minutes and very tiny and just a few (but visible), I can see little movement if I open the reservior and look inside but very very little movement. But once again I drove for 10 minutes in regular trafiic and the gauge reaches 1/2 (not normal)
Also I checked the oil again and sems to be kind of normal for me and perfect level, By the way, with the temperature gauge in 3/8 I touched the 2 hoses of the coolant (the ones I see) and the one that goes down of the reservior was hot and the one that goes down and out of the radiator and is connected to the thermostat was just warm, does it says something or not ??

Also, do you guys think that with the details I have mentioned could the problem be the thermostat or it does not seem to be the guilty??

Thank you.

Default Re: Saturn SL1 Overheating Problem

Assuming the ECTS ind relaterd circuit is good:

For the '99, on the open road the temp gauge should be at about 3/8 scale. In slow/stopped traffic (with the A/C off) it will slowly climb above that to a bit under 3/4 and then the fan should come on. It should never reach the red zone.

With respect to brown, has the coolant ever been replaced? It came with DexCool (orange color), which has a nominal life of about 5 years. Lots of people forget to change it, and the color may gradually change over time and with age to brownish.

On the s-cars the t-stats tend to fail in the open position resulting in the temp gauge staying at 1/4 scale or lower on the open road, and hurting MPG. It is unusuall for a t-stat to fail in the closed position except as a result of a botched replacement. If the temp gauge sits at 3/8 on the open road the t-stat is likely OK.

Not unheard of for a radiator fan to get weak as it ages and not blow with full force when it is on - worth chcking if open road temperaturs are OK. Also it is possible for a radiator to get somewhat cloggged resulting in less efficient cooling and this could cause overheating under heavy heat load circumstances. This is most often the result of lack of cooling system maintenance and/or use of stop leak like products.

Does the car overheat when you are driving on the highway?

Or just when you are moving slowly or stopped?

If the car does not overheat when driving steadily at speeds over 40 mph, or if the car starts to overheat and then cools back down when you can get the car moving over 40, suspect the fan. The water pump is still circulating coolant and airflow through the radiator over 40 mph is cooling it off.

If it overheats under both situations, suspect a blockage. Brown is not a normal coolant color.

Directions on how to flush are posted several times on this forum - if you do a search for "electrasol" or "dishwasher" that should turn up a few. I know I've seen pictures with a few of them. It's not difficult, even for a novice.

Default Re: Saturn SL1 Overheating Problem

Thanks to all for your valuable help

Yes the car is still overheating under all situations but mostly in stop and go traffic or traffic on regular streets, I guess the only desperate thing to do is replace the thermostat and yes, I will flush the radiator because I have never done it before (I only add more and more coolant when was need), do you guys know any recommended liquid to clean the radiator when flushing
or after the flushing (I don't know the process), is that "electrasol" one of them or is there something better for that purpose ?

Thanks to all, I will qualify you as the best !!

Yes, use any automatic dishwasher detergent. heck I even have a near-full bottle of Cascade locked and loaded just for this purpose (and others have suggested I sell all that excess on ebay or craigslist as "magic flushing fluid" )
