Brake Fluid Reservoir Filler Cap

Purpose:   To top up brake fluid if required. Essential to ensure brake safety.

Spec: Nothing amazing on the reservoir itself, but the brake fluid recommended is Universal to DOT 4 (Duckhams Universal Brake and Clutch fluid)
The brakes on the XS are 9.7in diameter solid discs at the front and 7.1in diameter drums at the rear. Assisted by a vaccum servo.
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Improves braking performance when the footbrake is applied. It gives more power to the brakes with less effort.

Spec: No extra detail is available at this moment in time.
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Key component in the engine in controlling the air and fuel mixture entering the cylinders. Mechanical in form compared to injection engines which are controlled by engine management computers.

Spec: TU engines have either Weber or Solex carbs. Mine is a TU3S engine which has a Solex 32-34 Z2 twin-choke carb. It runs using unleaded fuel as the ignition has been retarded for this. Many still run on leaded/LRP petrol.
 
 
 
 
 
 
 
 
 
 

Purpose:  Protects the air filter element and carburettor and also allows passage of air from the cleaner into the carb.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Cleans the air entering the carburettor, to prevent contaminants in the air/fuel mixture in the engine. Particularly useful in inner city areas!

Spec: Of the tall cylindrical variety, a comparatively large air filter.
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: To provide a flexible support between the engine and the body of the car.  Comprised of hard rubber block with metal facing plates.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Provides a 'reservoir' to allow the coolant to expand when hot.  To be topped up with water/antifreeze mix when required. The coolant system runs through the radiator at the front of the engine and also into the heater matrix, behind the centre console inside the car.

Spec: the capacity of the cooling system is 5.8 litres
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Relays sparks into the cylinders to create combustion within the engine. Part of the ignition system which includes the spark plugs, HT leads and distributor.

Spec: A breakerless electronic ignition system is fitted.
Ignition coil dynamics:
Primary windings        0.8 ohms
Secondary windings   6.5 K ohms
 
 
 
 
 
 
 
 
 
 

Purpose: Contains either water or a mixture of water and screenwash. Controlled by a small pump at the base of the bottle, fluid is squirted onto the windscreen via jets and cleared by the wipers.

Spec: unknown capacity, any regular screenwash is useable. Rear wash/wipe also at back of car, fluid reservoir at right side of boot.
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: To determine the level of oil inside the engine. Has two marks, the level should always be between them, preferably near, or at, the top mark.
 
 

Spec: 3.5 litre capacity, 10W/40 or 15W/40 oil.
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Powered by a drivebelt off the crankshaft pulley, it generates electricity through the engine turning. This is then used to maintain power in the battery but also to power the electrical system when the car is running. Flat batteries are often caused by too many short journeys, where the alternator cannot replace the energy used by starting the car up.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 

Purpose: Passes the air/fuel mixture from the carburettor into the four combustion chambers.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Pumps the fuel into the carburettor from the fuel tank, through the fuel filter.

Spec: Mechanical type
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: powers the electrical system and ignition system of a car using stored charge.

Spec: 12 volt, negative earth system. Low maintenance or maintenance free batteries with variable capacity.
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Collects the warm air rising off the exhaust manifold, which passes the hot exhaust fumes from the engine out through the exhaust pipe. The air is then passed through the air hoses and into the carburettor and aids the warming process of the engine this way rather than using cold air.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Allows the engine oil level to be topped up, by unscrewing the cap.

Spec: As for 'engine oil dipstick'
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Connects between the spark plugs and the distributor and relays the individual sparks into each plug, in the set firing order to each cylinder.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Passes the air from the exhaust manifold shroud and radiator through to the carburettor to decrease engine warm-up time. Controlled by a temperature sensor and shut-off valve.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Protects the cylinders from damage from water or any external debris and help reduce the amount of fumes released from the heating of the oil, when the engine is warm.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Protects the timing belt which helps maintain the timing of the engine, for best performance. Can be quite easily removed, though timing belt renewal is best left to expert mechanics and Peugeot dealers, with the right equipment for the job. If a timing belt breaks it is likely to cause tremendous damage to an engine, so renewal is recommended every 46k or so, or if a new car is purchased.

Spec: No details
 
 
 
 
 
 
 
 
 
 

Purpose: Recycles fumes from the engine back into the carburettor.

Spec: No details
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Purpose: Allows the radiator to be filled when replacing coolant (recommended every 2 years). As a quicker alternative to using the coolant expansion bottle. Can also be removed for the reason that it will prevent air locks when replacing the coolant.
