So do both the heater hoses get really hot?Also does the radiator fan work correctly?
yes the fans are working correctly, as far as both hoses I know that the top is holding pressure and it does feel hot the bottom is also holding pressure.
So are both heater hoses getting really hot?Are both upper and lower radiator hoses getting really hot?Hows your radiator cap?
Both heater hoses and radiator hoses are hot after car is running. As far as the cap, it still is having the back flow to leak out from under it. Also want to say thank you for helping.
What is the engine temp when this happens ?
I really don't know the temp, can say that it is not long after you have had the car running when you shut the car off you can hear the coolant gurgling in reservoir that is when it overflows under cap when touching hoses they are hot.
Are the fans running when the coolant is backing up ?
yes the fans are running. thank you for trying to help
How high does the temp gauge show when the coolant is overflowing?Higher then it normaly runs?Also to properly diagnose a coolant temp issue i would invest in a infared temp gun.They have gotten pretty cheap and will tell us what temp the fans come one and the over flow happens.Also can use it for many other things and future issues.
the temp gauge shows it to be running normal it only moves towards high end when coolant is getting low or gauge moves when it is gushing from resevior
