Havint problems over heating
Im having some overheating problems gm has had my car now for 2 weeks. At first they thought it was my thermostat going out, but it wasn't. They have tried a compression tester on my coolant and it tests out just fine. They replace some other sensors and still it over heats, jumps up to 230 to 269 degrees. The head gasket its fine. There is no sing of coolant in my oil pan or oil in my coolant re savor. The lines are pressurizing way to much and not allowing the coolant to pass threw. Sometimes it works then sometimes it wont. The coolant also gets dumped all over the ground from the re savor, it as well has been replaced twice.
Anyone have any ideas on what it might be now. Gm is stumped like me

It could be a bad check valve in the coolant system. I understand that without the check valves, because of the placement of the over flow bottle, that air can get sucked into the heater circuit and lock the system from flowing. I am not sure which hoses the valves are in but I try and research it.
Is there any way to bleed out the air in the heating system ? The other day i heard air flow threw the heating system when i first started the car. Sounds like a sink running or a drain ...draining. I've been watching my temps like a hawk but they haven't changed ....... Thanks for any advise .

yes radiator fans come on and no leaking
Yes but out of the re savor. The re savor has been replaced twice and still the system pressurizes way to much, and pops the seal under the re savor. There for my coolant leeks out every ware. My hose gets so under pressure u can barely pump it on the top side and for some reason it wont pump back in the re savor like when its cold u can pump fluid back to the re savor.
i having that same problem is that what that sound is. Could that be the cause of my car over heating or pressuring to much.
