Clio temperature gauge

Could someone please help. When I get into my car, the temperature light comes on and the gauge goes up then back down then up again. also only cold air comes through the vents when i put the heating on. Any ideas would be appreciated. Thank you

Start by checking the temperature sender/thermostat.

Thank you for your advice - looks like It needs to pay a visit to the local garage ! Bad time of year for costly vehicle repairs

Anyone else think it could be the same problem ?

Top up the radiator water, and if that doesnt help, change the thermostat as it sounds like it is stuck open.

hi, the temp gauge going up and down is normal, usually a oil level indicator.

the lack of hot air is probably down to low coolant level. The caps are famous for opening to soon allowing steam (and hence water) to escape.

Check the level when cold. if its low, top it up, then look for bleed screws on the coolant pipes, open these one at a time until water comes out, keep topping up the bottle. then run the engine with the bottle top off and give the rad hose a squeeze or ten. once it gets near warm, replace the cap and take for a drive.

see how it goes, you may have to go through the bleed again
