overheating

[KyleBailey7791]

was out saturday in the car, noticed the temprature gauge was about 3/4 of the way up and rising, it did end up all the way up with the light on, i parked it up left it cool down , the fan did kick in was on for about 10 mins after, checked iff there was (mayo) as they say in the oil but nothing, the heaters also work . and the waters fine. any idea what it could be ??

Thermostat could be knackered or it could be that the sensor for the dash is knackered, take the thermostat off and put it in boiling water and see if it opens, if not then its FUBAR'd

As already said by Brettles1986 - i would change the thermostat and then bleed the cooling system.

thanks guys, i am a bit of a noob when it comes to meachanics, i mean i dont know where the thermostat is on the 1.4, would it be a hard job to do or am i better off taking it to a garage???

Changing the thermostat is easy, its at the engine end of the upper radiator hose and is held on by 2 or 3 bolts.

Often suppliers will give you a Stat+housing, some just supply a stat and new seal.

The hardest part is bleeding the system and making sure you dont have an Airlock in your water which will cause more overheating.

do i need to drain the water out before taking the thermostat off

You don't have too. But you might aswell, if its already over heated. Best start from the beggining. Just take the small top hose off, water will obviously come out but if you hold the pipe upwards you can avoid wetting to much.
