heating issue

[cancam99ss]

okay guys here we goo... today i was driving the camaro around town and as i was waiting at a light i started tk see smoke come out of the ngine, all gauges where working properly.... everything was coming out of the overflow tank, so i was like okay what ever the car wasnt over heating so, ten minutes later it happened again, i noticed this only happened when i was at a intersection or street light waiting. So it was late and i had nothing to do, i was able to replace the radiator cap that someone had told me this might be the issue..... Well enough i was ablr to get home and it didnt thow any water to the overflow tank. I just walked by the car since i got home which was 5 hours ago, any ideas, has this happened to anyone.....

smell? maybe power steering fluid got on to the block, or onto the pulleys ?

Did it smell like something was burning?

[cancam99ss]

it was defnetly coolant

[cancam99ss]

Nothing was burning and gauges stayed under 210.... Coolant was just boiling out of the overflow tank

[KMdef9]

Maybe time for a flush of the fluid. Have you tested the coolant yet?

[cancam99ss]

Tested the coolant ??

[cancam99ss]

How do you test the coolant

Was the overflow tank overfilled maybe? Other then that, maybe a bad rad cap or a head gasket issue

Check to c that ur fans are working. If they won't kick in on there own shen u check turn on the ac and try again if nadda there lies ur prob. Lastly what about the thermostat is it sticking

[JayTA98]

how many miles on the car? Have you done a coolant flush? have you replaced the thermostat? Like they mention before check your fans.

[cancam99ss]

I have a 99 ss m6 69k
Replaced radiator two years ago, replaced thermostat 7 months ago, and replaced radiator cap on Sunday, coolant flush 5 months ago

Did the rad cap fix it? Or are you still having problems?

[cancam99ss]

Going to check it out today......... Haven't driven the Camaro since sunday no time hopefully today and keep u posted

[cancam99ss]

Issue fixed it was the rad cap

[JayTA98]

Issue fixed it was the rad cap

nice!

So after I thought this was fixed it's not... I started the car in the first time in 2 weeks drove it for about three miles I left it parked and on for about 10 minutes nothing happened. As soon as I turned it off I heard it boiling but the temperature never went up.... I took a vid and will be giving you the link soon

The stock coolant temp gauge isn't really a gauge. It'll sit there and read 210 all day long but the actual coolant temp can be anywhere from 180ish to 235ish. You can read the actual coolant temp on a scan tool or a separate aftermarket gauge.
Testing the coolant's protection level will help tell what the coolant/water mixture is. If its way off (too much water...I believe) the coolant will boil at lower temps. Its a good place to start.
Another possible problem is non functioning cooling fans. The Low speed comes on at 226 degrees, high speed comes on at 234 degrees.

Was also told something about back flow preassure

[Cutlass]

I'm not sure what that means? What did they say about it?
