Coolant help
hey guys I'm at Laguna seca and just boiled my coolant. I've let it cool and added water, I tried to run it with the cap off to burp the system and it was just spewing water all over the place within a few min. Let it cool for 20 min, put the cap on, and started and went from 190 coolant to 240 in 5 minutes.
Any ideas? Trying to salvage a track weekend

How cool do I need to let it get? Got it cooling for 45 min and that didn't do the trick.
This is the coolest track day I've ever done, 72, and the first time I'm having issues. Only change is the halltech intake maybe that turns up boost and lowers IAT temps too much.

Fill the tank when it is cool, say under 150 deg. When it is full replace the cap, start it up and run it at 2500 rpms for 2 mins. Open cap and add water as needed.
You probably have air in the system.

Mine did this same thing, I could not figure it out, the dealership replaced the water pump but I have not track since, I am running VIR this Monday/Tuesday with the NCM so we will see.
As a side note I did have a 170 therm in it and I was not sure if it "cocked sideways" as it was a Lingerfeild and they have recalled as the diameter was to small.

I sure hope this isn't the case for you but back in the day overheating caused some blown head gaskets. Tell tale sign was piston compression being pumped into the cooling system then pumping out coolant from the overflow, radiator or exhaust.

I'm sure there is a special coolant refill procedure in the service manual. If you follow those procedures and it doesn't solve the problem, which I am assuming is air in the system, I would give up on the weekend. Ruining an engine would be a high cost to pay.
If you don't have the service manual, I think the owner's manual probably has the information.

Speaking of that line, I see only 1. I assume that's the min line?

Well unfortunately no luck and I'm heading home. Overheated going 5 mph in the paddock. I think the water pump may be bad because I never saw bubbles coming out and the car would just boil and overflow at about 220 when idling.

Not sure this will help - a little "apples and oranges", but the principal should be the same. I had a young friend with the same problem you describe with his Firebird. He changed the thermostat, hoses, etc., but no fix. Finally, I had to "crack open" the system and manually fill the entire system from the highest point in his system, which happened to be the intake manifold boss for the thermostat housing. It took some time, but I finally got all of the air out of the system, and he never had a cooling issue after that. Any time there is a water passage above the point you are trying to fill from, it is difficult to remove trapped air. When the car has a low hood line, it can make the problem worse. On my race car, I have a vent fitting at the top of one end tank (Ron Davis radiator) with a hose running to the top of the surge tank mounted higher than both the radiator and the motor. Again, not sure this will help you, but it sure sounds like trapped air in the system to me. Good luck.
