Low Coolant light yet again.
 

Hello. This damn thing won't shut off and I've burped her blue.
Is there a sensor? It flickers off and on through turns and stays on the rest of the time.

I keep checking fluids and jacking it up. No bubbles. Push on hoses, nothing. All fluid levels are the same as I left them when I re-check.

Nothing going into the over flow. I'm perplexed.

Thoughts or comments would be greatly appreciated.

Coolant sensor is in the overflow jug on an 87

I keep coming back to that.

I'm thinking that there is supposed to be some fluid in there to shut it off.
But I'm not sure. That was a conversation from a ways back.

Problem solved. I put some fluid into the overflow and that shut it off.

Ya ya. It's my turn to wear the sign.

IIRC, the overflow (actually a reservoir, not quite the same thing, but whatever) is supposed to be filled to the "Full" mark when the engine is at operating temp, and between Full and Low at when cool.

You may feel free to overfill the reservoir if you're burping the system or unsure if you've got a leak and want a little security. After a hard drive the reservoir will purge the excess and level out right about where it needs to be. This is the best way I've found to burp the system with little effort although, you'll be nervous about the green puddle under the car for a little while. ;)

Leaks don't surprise me.
I'd be more concerned about the belts.

I'd remove the heater core but I think I like the thought of warmth in the winter. We'll see how she holds up and what I'm actually driving by then.

Hey, didn't you go with a MHG?

If the coolant overflow reservoir goes low every week or 2 and you know it's not leaking on the ground......

I hear you . I just topped it off after the initial fire up. It never had anything in it and I didn't rtemember till I made an ass of myself.

I think everything is fine. I haven't put 12 miles on it yet. I just forgot being a tard.

I also changed the oil yesterday, Beautiful and clear.

Yes it is.

I laugh when people jack the car up, put it on ramps, park on a gnarly hill to quote unquote burp the system. The people who do that have a BHG and are in denial.

Thanks for the advice. I'm quite sure I haven't blown this gasket just yet.
It's running tighter than a nun at mass on sunday.

Besides I just need it to run long enough to find a 7m-gte front clip and ecu and do the swap when this ge dies.

I'm pretty confident in the integrity of my build even though you don't seem to be. And that's cool. I'll get some pics up after the back glass is installed.

I burp the system with the nose up because It's the best way I know how man. I'm sorry I'm not up to your level of perfection. I get what cre's saying about purging as it does naturally. But I'm not running my roller like that just yet.

I have to put the 1k miles on to retorque. Hopfully, HH You're wrong this time.

Dude, I'm far from perfect.

I thought you were a diehard N/A guy supramacist?? Kinda like mr nickle boy.

I'm not trying to be right, I just like to spread facts. Like about the burping crap. It's a waste of time and effort. I'd rather just sit back have a beer or a smoke and let her do her thing. Patience is a virtue. Because if she doesn't do her thing, something is wrong. And I am NOT talking down to you or doubting your skills!!! Why do people assume THIS?!

The sooner the retorque, the better. I wouldn't wait that long.

Couldn't agree more. I've had my system drained once every few months for one thing or another and NEVER had to "burp the system". Besides, it's hard getting the car to stand on it's hind legs and I have yet to see a jack that goes as high as everyone says you need.

Don't get me wrong. I dig my n/a lilke a grave.

But if I'm going to go through this mess again. It's going to involve a turbo.

Now I don't get what you guys are saying....., it's always been a burp deal to the best of my knowledge. I'm going with what I knew for how I had to operate on the car when I acquired it. She was sick. Maybe I need a neww mind set.

Is the waterfall a symptom of bhg? Because I haven't heard it since my build. I had a brain fart about the coolant overflow.

I just remember how anal you were about things back in the day when you were a regular here. You and cre are grasping an entire different bar than I am. But I'm reaching. I'm sorry if I ruffled your feathers. I'm sure it has to do with my contankerous whore of a supra.

It's good to see you back HH.

Hence my other post.

The "waterfall" is a symptom of a BHG.... SOMETIMES.

The ONLY thing it indicates 100% is that there is air in the coolant system. Whether the air is present due to boiling, loss of coolant or the introduction of exhaust gases to the coolant system is the real question.

I can dig that.

I just need a better way that burping to ensure my personal security in the low coolant light staying off.

i haven't been following the thread , but i gather that there's been a metal head gasket used ?
i assume you have checked for leaks

loss of water happens in one of two ways

it leaks away
it burns away

once you see the "bird cage" and keep having to fill.

it's only one thing , you're loosing water

so if that light comes on this week again you're screwed

In so many words, ddmcse is correct. So is cre, dead on correct.

If you ruffled my feathers, I wouldn't bother to post in your threads. :)

Thanks but I'm not having any type of over heating.
No signs of any of that. It's running perfectly. I just forgot to add some fluid the overflow reservoir.

It'll start, run, and drive after I get it back together.
It just won't stop idling so darn high.

Different thread though. I have this thread under control gents.
Thanks kindly.

I know you want to see this thread die, so just hear me out one last time.

Rule of thumb I LIVE by:

If you open up your cooling system, you are allowed only 1 birdcage light. If it comes on AGAIN later that week, (2 weeks, a month or even a YEAR, yes a year should go by and the light should NEVER come on, like me), Then, like ddmcse said, you are screwed hardcore style.

I gotcha. I flushed it last night and haven't topped it off yet.

After I last topped it all of and added fluid to the res. No light.

I'll keep you posted after I top it off again tonight.
