Hi guys,

I have search the older posts but nobody seemed to have the same problem. I got my Sri about 10 months ago and always there has been a lot of pressure on the expansion tank even when cold. Last week, the internal heating was not working and the engine started to heat. I then stopped looked everything and release the pressure and everything want back to normal and the internal heating worked again.

This morning I noticed that the engine temperature was very low, below 90, and then a couple minutes later the internal heating was not working again. I stopped the car release the pressure and the engine temperature was back to more than 90 and the heating was working again.

Could it be that head gasket is gone and is breathing in? I am not sure because the car is not overheating.

Could it be an air intake problem? How do I know without taking to the garage?

Many thanks

Hi Gambit, sorry for my ignorance, but how do I flush the system? Is it just flush the water system and refill it with antifreeze? Is it covered in Haynes manual?

I'll second what gambit said. Place to start anyway.

Drain all the coolent out of the system from the bottom of the rad, then stick a hose pipe in the expansion tank and let it flow through for a while. I then fill it up, run it for 10 mins or so, then drain again, to get all the dirty water out. Then refil with new clean water and antifreeze.

If you leave the engine running with the header tank cap off til the fan comes on then it should get all the air locks out of the system, also squeze as many pipes as you can go clear air locks.

note, dont put cold water in a hot engine.

make sure your heater setting/knob is set to max heat, otherwise you'll get another airlock!!
