   first thing i would think of is headgasket, check for mayo under your oil cap and for sludge in your coolant.
   
   if none of the above then id check your thermostat

   cheack see how hot your engine, coolant pipes get. if not boilin over then might be a dodgey sensor. mine was up near red after buyin it new thermostat sorted it. sits above half most of time.stays there tho kept risin to red before.

   The above advice is all good, it'll either be head gasket, thermostat, air in your coolant system or a faulty sensor. Saxos always run quite hot but the gauge shouldn't go anywhere near the red.

    Mines been overheating recently.
    
    Headgaskets don't usually just go without a reason. If youre on 60,000-80,000 you may want to get it checked. Easy way to tell, is there white sludge on the oil filler cap? If not it probably isnt that.
    
    Run the car for a bit and see if the fan kicks in (as suggested above). If it dosnt, check your fuses under the bonnet. the fan is two 30's next to each other. but replace any if broken.
    
    If not, may be either the fan (ive got a spare if you want one?) or the coolant temperature sensor.
    
    Try to find a scrappy with those.
    
    But first, take off the three bleed screws (right hand of radiator, then theres one to the right of the rocker cover - this is the temp sensor one, you'll need an allen key, then there's one at the drivers side right at the back on a bend in a pipe, looks like a tyre valve cap). Once they're all off, fill with water completely, replacing each bleed cap when water starts pouring out. DO NOT REPLACE THE WATER FILLER TANK.
    
    When you've done that and you're sure its full, start the engine, idle at 2,000 for a bit to speed things up, then when its at 1\2 temp, pull forward a car length. when its over 2/3 temp, get out and lookunder the bonnet. If there is water anywhere other than underneath the filler tank then you've found the problem.
    
    If not, try replacing the sensors. Most likely to be the thermostat. You can pick them up in halfords for £7ish.
    
    Dont bother getting the head gasket done until youve looked for all other possibilities. And don't run the car like this! You'll DEFINITELY do the head gasket if you do.
    
    
    If after all that it is the head gasket, you're looking at a good £300-£500. VTS conversion time?

    yeah its not a constant overheating, just has random moments while driving whe its goes right 2 the top then gradually comes back 2 normal driving temp... its crazy but i do have a few options now and the thermostat thing sounds like a good call, if it was the thermostat that was dodgy though it would'nt cause the fan2 kick in right ????

    If it was on the blink it might work sometimes and not at others. If the fan didnt work at all it would be the coolant temp sensor. But most probably the thermostat (if they didnt go all the time halfords wouldn't stock them )

    My fan kept coming on for now reason as it over heated, my radiator had a tiny leak so any water to cook tge car down was leaking. Could add water to the radiator and check if the level drops
