Ford Sierra overheating

[05omegav6]

Just a thought, but have you tried flushing the heater matrix, radiator and engine separately 

[Steve Brookman]

Thats the next thing to do, but heater was working very well until temp rose.
Noticed as well that the car seemed to missing on tickover-suspecting a possible head gasket as well.

Cheers Steve

If that the case suspect a crack between 3 and 4

Thanks

Friend having a look on Wednesday.

Sorry

Have had 2 2.0 twin cam Granadas in the family, both suffered head failure at about 120k, and both failed in an almost identical way... 

Fingers crossed for better news

[Steve Brookman]

Thanks
Has been in the family for 13 years so will be repaired whatever is wrong, only thing that has gone wrong in 13 years apart from a torque convertor seal which cost me £140 to have fixed 10 years ago. Bodywork is excellent for the year and it's usually quite good on fuel, though I have noticed an increase revently perhaps due to the HG.

Thanks

Hopefully you'll see another 13 years out of it It's obviously a Cologne built one , they do seem to be a bit more rust resistant than the Ghent ones

[Steve Brookman]

Quick update.
Had sniff test done-HG okay.

Changed engine fan sensor and temp guage sensor.

Still going way up when pootling around-on a run it's around 3 o'clock.

Had it ticking over in work - drivers side fan came on when gauge was nearly on the red-but I could still hold the top hose for quite a while.
Borrowed a infra red thermometer from work. When we got home and the guage was way up-the top hose was around 75 degrees and the bottom hose 85 - 90 degrees. The fan then came in.
It doesn't seem to be overheating but when it's up high on the guage-the heaters blow cold.

Will flush heater matrix this weekend.

Cheers

Good news

Hopefully a flush will cure it, I don't envy you the task of changing it if it's shot

[Steve Brookman]

Thanks Al,

I hope it's not completely shot-I sometimnes hear a swishing noise so am hoping there is air in it.
Will have a look tomorrow!

Cheers

Steve
