I was swapping out RMI and water for coolant/antifreeze yesterday and during this time my engine coolant temperature went to 225*. I have put 2 gallons of coolant in the car and I didn't realize my fan wasn't plugged. I plugged it in and the coolant was circulating, but the temperature kept creeping up. So I decided to shut the engine off, the reason I figured it wasn't cooling enough is that I needed coolant. I'm sure once I shutdown the car the temperature rose a little more I'm sure to around 230*. Just wondered it this temperature could warp the aluminum heads? I had my wife pick up another gallon of coolant and I went out and started my car again about an hour later and the coolant temperature was down to 134. So I started to the car to let the coolant get circulating again and this time I couldn't get the car to go above 170* despite the fact that I had not adding any coolant. So I had to unplug the fan again to get the coolant flowing and then I added about a 1/4 of a gallon and the damn thing was full. I plugged the fan back in at let the car run again and it was staying in the 160s. I got scared when the car hit 224, so I turned it off. I probably should've kept it running and the temperature would've went down, but I wasn't sure and I didn't want to ruin my new build.
Just wondering what temperatures it takes to warp the heads. The head on my Cruze is aluminum and the base operating temperature is 224*. The aluminum head on my Cruze is probably made of a different grade of aluminum.
Thanks.
Anybody ever warp aluminum GN1's
