[AR-FRST]

Hi Guys,

Having just received my FRST back from a local garage for an MOT (failed - wheel bearing) Which i was very impressed considering the age of the car (H-Reg)

A full coolant (Black) Roose set has been fitted & the car was running great until I drove it on the motorway. I didn't hit the speed limit of 70 just to be safe i kept the Fiesta at 60.

All of a sudden the temp gauge started to climb BIG style. In the red. I pulled over & could see steam coming from the brand new plastic header tank. The water was bubbling.

Having now got the car at home I let it cool & removed the header cap. Zero water. I have now filled the header tank to the max line & left the cap off & the car idling.

The water level started to rise. I have read on a few sites (this one included) that I could have an air lock.

Also the heaters do not work. They did not work before the above work was undertaken.

Any ideas?

Thanks.

sounds like an air-lock to me mate, also it sounds like your heater matrix could be blocked, this could be causing the airlock

I concur try a good flush and reverse flush

Reverse flush?

Flushing not just from the header tank but flushing by inserting a hose lower down in the cooking system
