today i did a run up the motorway and i noticed that the temp gauge was awfully close to the red marker and noticed if i went quicker it got closer, if i slowed it went down, its never done this before, always stayed like level, any ideas what could be wrong ?

losing any coolant??

going a little faster should really drop the temperature due to higher air flow, either you have a cooling problem or a wiriing fault.

Preety much your case. 2-3 good flushes, replace the coolant (using a good one), test the radiator (replace if necessary), test the thermostat (replace if necessary or in case of doubt), test the two temperature sensors (and see if the fan works or not, much before the red mark), change the expansion reservoir cap and bleed the system properly.

Top up during the next 2 days (if necessary) and that should be all.


Ah! If you intend to replace the timing kit shortly, then do not forget to replace the water pump or, at least, check it (the inside part).

but mine dont over heat when stuck in traffic etc etc, the only time the temp gauge shoots up is when im doing 70+ on the motorway, if i dare go over 80mph then the temp gauge goes straight into the red. Ive topped the coolant up etc and still does it, what else may it be

The thermostat housing is at the back of the engine underneath the inlet manifold at the cambelt end.

Access from above and below is arkward and some pipework has to be removed first to allow the housing to be removed.

Not a job I would suggest you tackle if you are unsure.

Honestly its a swine beetch, basket, gunt job if you leave the inlet manifol in place which I reccomend.Use a 1/4" set for 'better' access and a long extension with a u joint.

Take the extra bit of time and remove the inlet manifold, it will save all the hassle, time spent and grazed knuckles trying to do the work with it in the way!

Garh! Thermostat is a nightmare!

I've just tried to do mine, I got it fitted but I'm loosing coolant from somewhere now, and I've checked the heater hose and nothing.

Buggering thing took me the best part of four hours thanks to having to backtrack and remove parts to get to other ones. The K-Series really is a tight squeese in the Metro.
