Had just a small leak in my thermostat housing got a new one out it on now it drives about 20 miles then straight to overheating temp gauge goes straight up no lose of coolant at all. After installing new housing I added coolant. All electric connections are back together just can’t understand how a small leak has turned into this any help would be appreciated

 

You have to coolant bleed the air out,there's a bleeder screw on top of the engine,

 

Man thank you for replying back I will do that now just open it up while adding coolant or start engine and close once coolant starts to flow

 

Hello, I'm from Brazil, I saw your post and I imagine your affliction. I had the loss of liquid bothering me for a long time, until I saw a video that taught me that we have to preventively change the water pump, the thermostatic valve, and the water duct that is behind the supercharger every 50,000 km. When changing the coolant, there are 2 valves that need to be open until the coolant leaks through it. There are two plastic screws that fit any tool to get all the air out of the system. After filling it with liquid, you can close the system and drive the car. The next day, fill in what is missing with the cold car.

Ola sou do Brasil, vi seu post e imagino sua aflição. Tive por muito tempo a perda do liquido me encomodando, até ver um video que me ensinou que temos que trocar preventivamente a cada 50.000km a bomba dagua, a valva termostativa, e o duto de agua que fica atras do supercharger. Quando for fazer a troca do liquido de arrefecimento, tem 2 valvulas que precisam estar abertas até que vazem por ela o liquido de arrefecimento. São dois parafusos de plastico que cabem qualquer ferramenta é para sair todo ar do sistema. Depois de você prencher de liquido pode fazer o fechamento do sistema e rodar com o carro. No outro dia preencher com o carro frio o que faltar.
