SEAT Workshop Service and Repair Manuals

Special tools, workshop equipment, test and measuring appliances and auxiliary items required

• ◆ T10007 Refractometer
• ◆ V.A.G 1306 Drip tray
• ◆ VAS 5024 Assembly tool for spring-type clamps

Not illustrated:

• ◆ VAS 6096 Cooling system charging

Draining

• ‒ Remove engine cover.
• ‒ Open cap on coolant expansion tank.

• ‒ Remove noise insulation tray.

• ‒ → Pull out retaining clip -arrow- for lower coolant hose and remove coolant hose from quick-release coupling on radiator.

• ‒ → To drain coolant from engine also remove coolant hose from oil cooler -arrow-.

Note:

Observe disposal regulations!

Filling

Notes:

• ◆ Only use coolant additive G 12 in accordance with TL VW 774 F.
  Distinguishing feature: coloured violet
• ◆ G 12 and coolant additives marked "In accordance with TL VW 774 F" prevent frost and corrosion damage, scaling and also raise boiling point of coolant. For this reason the system must be filled all year round with frost and corrosion protection additives.
• ◆ G 12 violet (in accordance with TL VW 774 F) can be mixed with the previous coolant additives G 11 and G 12 red!
• ◆ Because of its high boiling point, the coolant improves engine reliability under heavy loads, particularly in countries with tropical climates.
• ◆ Protection against frost must be assured to about -25 °C (in arctic climatic countries to about -35 °C).
• ◆ The coolant concentration must not be reduced by adding water even in warmer seasons and in warmer countries. The anti-freeze ratio must be at least 40 %.

• ◆ If for climatic reasons a greater frost protection is required, the amount of G 12 can be increased, but only up to 60 % (frost protection to about -40 °C), as otherwise frost protection is reduced again and cooling effectiveness is also reduced.
• ◆ The refractometer T10007 is recommended for determining the current anti-freeze density.
• ◆ If radiator, heat exchanger, cylinder head or cylinder head gasket is replaced, do not reuse old coolant.

Recommended mixture ratios:

    1)    The amount of anti-freeze must not exceed 60 %; frost protection and cooling effect will decrease if amount of anti-freeze is too high.

    2)    The quantity of coolant can vary depending upon the vehicle equipment.

• ‒ → Install lower coolant hose and secure with retaining clamp -arrow-.

• ‒ → Push coolant hose onto oil cooler connection and secure with a spring-type clamp.

With cooling system charging unit VAS 6096

• ‒ Screw adapter V.A.G 1274/7 onto expansion tank.
• ‒ Fill coolant circuit using cooling system charging unit VAS 6096.

=> Operating instructions for cooling system charging unit VAS 6096

Not using cooling system charging unit VAS 6096

• ‒ Turn off heater control.
• ‒ Press top radiator hose down.

• ‒ → Fill with coolant slowly up to max. mark on expansion tank. Filling takes approx. 5 minutes.
• ‒ Start engine and run at increased idling speed (about 2500 rpm) while filling expansion tank up to MAX. marking with coolant.
• ‒ Fit cap to expansion tank cap.
• ‒ Run engine until radiator fan cuts-in.
• ‒ Then continue to run engine for about 10 minutes at increased idling speed (about 2500 rpm).
• ‒ Check coolant level and top-up if necessary. When the engine is at normal operating temperature, the coolant level must be on the MAX. marking and, when the engine is cold, between the MIN. and MAX. marking.

• ‒ Install noise insulation tray.
