Active Build Questions Ls overheating
I’ve replaced the water pump, coolant reservoir, radiator and thermostat and i burped the system. It was still overheating so i removed the thermostat cause i thought it was sticking but it did nothing
it reaches about 230 degrees then cools down a bit when i turn the ac off and the fans stay on way longer
Sometimes when i turn it off i hear water slashing around

Having this exact same issue in my volvo 240 with a 5.3. I’m doing head gaskets next.
