Noticed this morning that the water in my 2wd saph is bubbling out of the header tank. When it gets warm the water stops flowing from the pipe from the turbo and seems to be coming back through the pipe from the pump. Has this happend to anyone before or does anyone know what could be the problem.

 

Plus the fans are not coming on when hot.

 

Anyone with any ideas.

 

There's a lot of overheating and temp gauge problems recently..must be something in the water.

Sounds like the thermostat's not opening perhaps? They don't cost much (an 88 degree one's only a tenner) and are reasonably easy to change, so you might be as well doing that - you can also test yours while its out
