Holden Astra Problems

No car is perfect, but we've gathered everything relating to the Holden Astra reliability here to help you decide if it's a smart buy.

Why is the coolant in my 2007 Holden Astra a milky colour?

Answered by CarsGuide 10 Feb 2021

The first response of most mechanics on this would be that you have a head gasket leak in the engine. Coolant in the oil and/or oil in the coolant are classic symptoms of this. It happens because the faulty head gasket allows the two fluids to mix but, depending on exactly where the gasket fails, you don’t necessary get both symptoms. A workshop can pressure test the engine’s cooling system and perform what’s called a TK test to show up any contaminants in the coolant that have found their way there via a blown head gasket.

But before you go tearing into the engine, check the service records to find out how old the coolant is. Coolant will discolour over time and kilometres and what you’re seeing as a `milky colour’ might simply be old coolant that has gone cloudy and needs changing.

Why does my 2017 Holden Astra jerk when I put it in reverse?

Answered by CarsGuide 4 Nov 2020

The jerk when you select reverse sometimes is definitely worth having diagnosed properly as it shouldn’t be that way. Scanning the car (which I’ll presume the dealership did to arrive at its answer) doesn’t always show up all faults, so just because the computer says there’s nothing wrong, doesn’t mean there isn’t. There are plenty of reasons for a car to jerk into a particular gear, but the good news is that the Astra uses a conventional, torque-converter automatic, not one of the vastly more troublesome double-clutch units.

Your second problem, however, may not be a problem at all. In fact, the gearbox in the Astra is smart enough to know that you’re coasting down a hill and will actually shift down a gear or two to take the strain off the brakes while still maintaining your speed. As it shifts down gears, the engine revs will rise; that’s absolutely normal and part of the way the car is designed to operate.

Why does the clock in my 2004 Holden Astra CD keep resetting?

Answered by CarsGuide 26 Oct 2020

My first thought is that your car’s battery is on the way out. Are there any other symptoms of this (slow cranking etc)? Essentially, a battery that isn’t fully charged or is a bit wonky can start to shed its responsibilities one by one as it wears out. In this case, you might find that maintaining the clock’s memory/time isn’t programmed into the car as a major priority, so it switches that circuit off as a means of saving every available volt and ampere for actually starting the car (which is the point at which the maximum strain is placed on a battery).

Beyond that, you could have a dodgy ignition barrel that isn’t making all the necessary contacts when you insert and turn the key each time. I’ve heard of applying a liberal coating of acetone (or a solvent such as carby cleaner or WD40 should also work) and inserting the key a few times in succession. This is sometimes enough to clean the contacts and restore full functionality.

Why does my 2009 Holden Astra have trouble starting after sitting overnight?

Answered by CarsGuide 11 Sep 2020

These cars used a fairly simply check-valve on the fuel pump to prevent fuel draining back into the tank when the car was parked. As the car ages, this valve wears to the point where it won’t maintain fuel in the lines going to the engine. If that happens, it will take some time and cranking to get fuel from the tank to the engine. This is the delay you’re experiencing.

The worn valve is only allowing a small amount of fuel to drain back which is why you need to wait six hours or so for the problem to show up. A new fuel pump will fix it.

What oil should I use in my 2004 Honda Astra?

Answered by CarsGuide 2 Sep 2020

When talking about engine oil (as opposed to transmission, brake, power steering, differential, radiator or other types of oils found in cars) for your Holden TS Astra, a 10W-40 rating is best, though 15W-40 is good and 20W-40 is also OK. Make sure to go with a trusted brand.

Why does my 2020 Holden Astra have an oil leak in the transmission?

Answered by CarsGuide 20 Jun 2020

You could argue the semantics of what is and isn’t a major failure till the cows come home and still not get any joy. But while I’d still be talking to the dealership, I’d also contact Holden’s Customer Service department and explain the situation to see if it will overrule the dealership’s call on this. The number to call is 1800 46 465 336.

Meantime, if the car is fixed and working properly, what’s the problem? You could get a brand-new car and have exactly the same thing happen, so where do you draw the line on what’s acceptable and what’s not? Had Holden refused to fix the car or done a botched job that still left the car with problems, it would be a different story, but if the car is back to brand-new, I would consider the problem to be solved. I’m tipping head office will see it the same way.

Holden Astra GTC 2015: Why is my car coughing dark smoke?

Answered by CarsGuide 30 May 2020

It sounds like you’re dealing with a fuel-air mixture issue when the engine is started from dead cold. If the mixture is too rich – which would be my suspicion – then black smoke is often a consequence.

A coolant temperature sensor should be telling the engine’s on-board computer what the temperature of the engine is, so that the computer can then tell the injectors how much fuel to inject into each cylinder. A dud sensor can cause the computer to inject too much fuel, and there’s the source of your black smoke. As the engine warms up, the sensor starts sending the correct signal to the computer and the smoke stops.

Of course, it’s not always that simple and you could also be looking at a blocked air filter, a blockage in the air intake system, worn fuel injectors and plenty more. Even a stuck or jammed thermostat can cause an engine to run poorly and blow black smoke if it can’t maintain the engine at the correct temperature. Old or stale fuel in the tank can also cause these symptoms. The fact that your car is not showing any fault codes suggests that perhaps you’re looking at one of these old-school problems.

Holden Astra 2006: How can I fix a broken CD player in my car?

Answered by CarsGuide 6 Sep 2019

Have a car sound system specialist check it for you. They should be able to clear it so that you can insert CDs.

Holden Astra 2003: Water pump and timing belt replacement

Answered by CarsGuide 10 May 2019

It’s common practice to replace the water pump at the same time the timing belt is changed because they usually need it. It doesn’t appear to be overheating, i.e. the gauge is not going off the scale, so I would just keep an eye on it and if it does show signs of overheating get it checked out.
