  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

I picked up a 3.8 genesis thats giving me some coolant issues i seen it was leaking i had someone come look at it and they said its the temperature control unit
So i went and got one along with a thermostat,intake gasket,and a cross over coolant pipe kit the water pump is new no leaks in radiator the fans kicked out when It started over heating no white smoke or milky oil i did a pressure test head gaskets are good and its leaking from the thermostat area i took everything out of my way on the left side of the engine bay so what im asking is what should I be replacing while im replacing the coolant control unit with all this shit open and what eles do I need to remove to be able to pull the temperature control unit should I replace the thermostat housing also im just trying to find some direction along with some advice on how I should do this 🤙🏼
