Thought i had sorted it got loads of air out left to cool then set off home from work temp went up then after 5 mins went cold again now scratching my head???? Could it be the head gasket???? gutted i love this car but if it carries on it will be scrapped

Also a bit confused people say change the water pump when doing timming belt mine isnt run off the timming belt its above the power steering pump????

Nice for a girl but not for me lol

The heater never really got red hot while iv had the car i put that down to losing water. the heater is better now when the car is stood just when driving it goes really cold and the temp drops to nearly the last line with the C on it is acting like the stat is gone but thats new and there was nothing wrong with the old one either. Im hoping it is a air lock i used to be a mechanic for 10 years just never worked on a lexus and one of my mates said he did a water pump on a audi doing the same thing and the propeller had feel off the back of it so i will have to see how it acts going to work today thanks for the reply

Right people were do i start ha ha Got the lexus is200 on a x about 6 weeks ago and it has always lost water but last few days more and more so found the leak it was the rad. But last few days its been running cold like the stat was stuck. So today i fitted a new rad and a new stat fresh water and anti freeze ran it up temp gauge went up and fans kicked in great thought it was sorted. So left work with in 2 mins the temp gauge was up 2 lines and heater was hot but after a few miles temp gauge dropped heater went cold got home left it at idle and it got hot heater got hot temp gauge was in the middle so took it a run again and every thing went back to cold?????????? Any ideas people i need help could it be the water pump??
