Partly covered: Vauxhall issued Astra handbooks before its August 2011 edition that it does not publish, and the editions around them print different fuse charts. A 2010 Astra may have one of them — check the edition printed in your handbook, or compare with the fuse box legend in your car, before removing anything.
Quick answer
VerifiedApplies toHandbook edition January 2010Handbook edition August 2010
Vauxhall’s 2010–2016 Astra handbooks label the engine cooling fan “Radiator fan”. “Fan control” and “engine cooling” labels are not included.
Vauxhall’s handbook doesn’t print fuse ratings, so none is shown. Fit a replacement with the same rating as the fuse you remove — the handbook says: “Data on the replacement fuse must match the data on the defective fuse.”

How to replace the fuse safely
- Switch off the ignition and all electrical equipment. Take the key out, or move a keyless fob away from the car.
- Open the fuse box and find the fuse using the number on the cover legend or the chart on this page.
- Pull the fuse straight out with the plastic fuse puller (usually clipped inside the fuse box) or fine-nose pliers.
- Look at the metal strip inside the fuse. A broken or burnt strip means it has blown.
- Fit a new fuse with exactly the same amperage rating. The number on top and the colour should match.
- Refit the cover, switch on and test the component.
- Never fit a fuse with a higher amperage rating than specified. It can let wiring overheat.
- Never bridge a fuse with wire, foil or anything else.
Fuse keeps blowing?
A fuse that blows again straight away is doing its job. Something on that circuit is drawing too much current. Common causes are damaged wiring shorting to the bodywork, a failing motor or socket, water getting in, or a faulty accessory. Fitting fuse after fuse, or a bigger fuse, won’t fix the fault and can overheat the wiring. Have the circuit tested by an auto electrician.

Stop if it overheats
If the temperature gauge climbs or a warning light comes on, stop safely and switch off. Never open the coolant cap on a hot engine.
Coolant level
Check the coolant level with the engine cold. Low coolant causes overheating more often than a fan fault.
Silent fan on a cold engine
The fan normally runs only when the engine is hot or the air conditioning is on, so a silent fan on a cold engine is normal.
