The thermostat for the cooling system can be found on the front of the engine. You can follow the bottom radiator hose to the thermostat housing. The thermostat will be within the thermostat housing.
Which model is it, year etc. on a 95 pug 306 XL 1.4 its quite difficult to get at ( im trying to change mine now) if you look at the rocker cover (top of the engine) its towards the cockpit at the back of the engine on the right. an easier way to find it is to follow the leads off of the battery one should go behind the engine and to the starter
Remove the water supply line to the thermostat housing. Remove the thermostat housing retaining bolts. Lift the old thermostat out and replace it with the new thermostat.
The 2003 Subaru thermostat is located inside of the thermostat housing, on the front of the engine. The thermostat will be near the bottom of the engine.
If by S16 you mean a Phase1 S16, then it is right above the throttle body, but on the other side of the bracket, right next to the cylinder head, with a plug on top of it. You can trace it from the TB as there is a hose running to it from the upper part of the TB housing.
With a commonly used oil filter spanner or strap or last resort screwdriver through it!
really easy fix! what model 306 is it? regards, Simon
Normally located to the right of the steering wheel. It is a numeric keypad.
with a complete standard pug 206 you should be able to do around 20 miles fine, anything over will be pushing the petrol gunk into your tank.
There is a TDC sensor on the front of the gearbox bell housing of most 306 Diesel models (up to MY '99 I believe) Neil
If by S16 you mean a Phase1 S16 then you need to take off the coil pack coverplate, the one that the fuel lines' securing metal plate is bolted onto. So 8 bolts need to be undone. Then you see the coil packs, 4 of them. Unclip them one by one and gently wiggle them out. The spark plugs are now accessible. I would recommend doing the swap one at a time so the coil packs can be placed back to their original cylinder.
Go to a gunsmith
