Coolant leakage. I've had that experience on my 2002 Astra 1.8. I've replaced with genuine GM parts throughout the year the following:

Radiator, NZD $516.

Water pump (as part of cambelt job, nothing actually wrong with it) NZD $149.

Thermostat, housing, gasket, sender, NZD $259.

My coolant level was always down, Turned out to be my radiator dripping from the o-rings on the sides. Not possible to fix, so off it went.

A few months later, coolant level was down again and the car was getting hot. Turned out the thermostat gasket was leaking and thermostat sticking. Off it went.

Astras are excellent vehicles when operating correctly. Owners MUST be constantly aware to check over the vital systems of the car that you wouldn't normally have to check so much on other models. This includes the fragile cooling system, aircon, electrics and cam systems. Servicing at Genuine Service Centres is the only way to ensure full support from Holden if anything goes wrong. It's happened to me, and they have always been forced to come back to the party.

To the guy complaining about the revving; that fault is most often caused by a faulty MAP sensor.

This sensor can be bought on Ebay brand new for $99, plus overnight shipping of $20.

It's very easy to fit, you only need a pair of pliers or a small 7mm spanner or socket. Undo 2 clamps and the wiring plug, and insert the new one. The job takes 10 minutes. My 66 year old mum could do it dead easy.

Holden will charge you $350+ to replace this item.

I just bought a new ECU on Ebay for $350 and a new coil pack for $99. Had a Holden dealer program and install the new ECU for $88.00.

All up cost $537. Now the car is good for another 12 years.

Have found you can buy everything online at about a quarter the cost of buying from a dealer. Sometimes even less.

New rear brake discs $45 each. Front discs $49 each. Pads $36 front and rear. Labour to fit at a local tyre fitter was $140.00.

Total cost for completely new brakes, front and rear = $400.00.

Timing belt full kit including bearings, tensioner, belt and water pump for under $200 delivered. Labour to fit $170...

Just a few examples...

Ignition barrels can be fixed by decent locksmith so it never break again for about $100.

Just keep your Astra away from Holden and you can't go wrong.

Mine's 12 years old, 330,000km, and motor, gearbox and everything are still going strong...

Holden dealers will fleece you every-time. I often think they create problems so you'll be back sooner.

I have a coolant leak too (01 Holden Astra).

Massive leak from the Y-shaped tube at the back and bottom of the engine, $160 from Holden only. Now I have a different leak from what I hope is the overfill tank; off to replace that now!
