Cribs: add coolant/distilled mix

Let car cool down.

Add coolant. Read about 50 bleeding threads! You don't have heat because of improper filling/bleeding of system. You evidently just noticed it because you maybe put on the heater, sucking up coolant, triggering low coolant light.

Add coolant or just distilled water...if you guys do that there! We're snobs here, many of us only give our cooling systems the finest in distilled water! You probably should too!

F! I can't write a short post...

Read a lot anyway, OP, but you should add a 50/50 mix of the coolant you used and distilled. If it's only a couple cups low...it is...distilled is fine unless you get really cold there.

I reread the part about heat...so you have heat when you turn on the heat, but you don't have heat when the heat isn't on? I think you meant something else...but the answer is still 'add coolant'

I think you just need to add coolant. If you did work a while ago, the bubble has probably come to the ET already, and you'll find your coolant low.

If not, you've got another issue.

If you want, I don't think you need to, but...

Key to Pos 2; car NOT started.

Heat on highest temp
Fan on low
Dial to three red dots

Open ET, bleeder screw...add coolant SLOWLY until coolant starts leaving bleeder screw bubble free.

Close up, start the car, drive around neighborhood to OP TEMP, and if it ever rises above dead center on temp gauge, get home, stop car, get back here and report.

If you don't overheat, get home anyway after getting to op temp. Let it cool, check level...it might be high.

That's why, for now, I think you should just add coolant as needed so you're between the min and max balls on dipstick.

Monitor coolant level periodically...more often after having any issues with it.

If you're just adding coolant, like I said, fill it so that the two balls on the floating stick, straddle the top of the filler neck.

The coolant itself should be about 5.5" below the filler neck.

You need air space above it.

Did you fill it to the top and drive and then it overflowed, or it's overflowing because you have the car running with the cap off?

In any case, get the car cool and adjust the level like I said.

If I misunderstood, let me know, British English is my second language!

Did you start the car? If so, I meant just add coolant when car is off.

The stick should not be all the way up, right...balls above and below the filler neck.

You have your bleeder screw closed?

If the car is on, turn it off, let it cool down.

Then open cap, check level, adjust as needed. Don't start the car, don't turn on the heater, just start with that.

Close things up, drive to op temp staying in the neighborhood. Get home when at op temp or just before...let it idle to op temp...turn it off, let it cool down. Open up ET and see what the level is at.

I think I wrote to do something like this first below...

(When you say it's overflowing, is it pouring out that little screw to the right of the ET cap, the bleeder screw? If so, it should be. If not, are you sure you opened the bleeder screw?
