I have a 1.5 dci 2001 and its on the side of the gearbox at the front of the car (passenger's side). It's a plustic plug which is easier to see from the bottom of the car.
Unscrew the sump plug.
The spark plug gap for a 2004 Renault Clio 1.5 liter 16v should be set at .9 mm. A new spark plug can be purchased at any auto parts retailer.
The size of the Renault mMegane Ssenic 1.6 1999 sump plug is 9mm. You can find this plug at the bottom of the gearbox.
could be glow plug indicator if its a deisel
8mm Square plug
Assuming that this is a manual gearbox most Renault models have a plastic butterfly bolt located on the front of the gearbox this is the filler/level plug
All the oil sump plug are on the lower part of the engine, in this case is the same, but you probably will no notice that because it is not a common plug, this car have a square plug.
on a mk1 clio just unscrew the screws in the front of the lamp and pull it out, twist the plug at the back and it should all just come appart
what model is it? i.e mk2 2.0 172 or mk3 1.2 16v? mk3 1.2 16v
0.9 mm 0.03543 inch
The spark plug gap is specific to the vehicle engine and not the plug. Your owner's manual and a placard under the hood will have this information. Also any parts store will provide this info.
If you see no obvious drain plug, then just remove the lower radiator hose to drain the system.
