Hi Jordan,

The two different 1.6-litre petrol engines available in the Astra J of 2011 used timing belts.

Hi Teresa,

There's no definitive answer to that, but let's talk through some of it.

First up, while three-cylinder engines might be less balanced and more susceptible to stress when pushed than their four-cylinder counterparts, that's entirely unimportant if you generally pootle around and don't extend the engine to its fullest. And you service it properly.

If you like your car and you don't have to change it, why bother? The more you change your car, the more it costs you in the long run after all.

Nonetheless, if you've got it in your head that you don't trust the three-cylinder engine for some reason, then both the 1.5 Golf and the Corolla are good options.

If all that matters to you is reliability, then it's hard to ignore the Toyota as it has such a strong reputation on that front. We wouldn't expect the Golf to be unreliable as such, but the Corolla is bombproof.

But there's a lot more to a car than dependability and if you already like the Golf, you may well prefer another one over the Corolla. The drive very differently and feel very different, too.

Our advice would be to go and test drive the cars for yourself to see which you prefer, but don't hurry into a decision if there's nothing wrong with your current car.

Hi Chevalier,

We have no way of knowing which setup your car's engine has remotely, but you are correct in that some of the engines from that year use a chain for the high-pressure fuel pump drive while others use a belt - alongside the main timing belt.

It doesn't really matter which your engine has, unfortunately, as the chain must be replaced just as often as the timing belt - at least every 200,000km or 10 years, whichever comes first.

Hi Michael,

If the car suits you now then there's no reason to change it. Sounds like it's barely broken in. Saying that, low mileage at low speeds does not suit diesel engines and their exhaust systems so make sure you take it for a good spin at higher engine speeds regularly to keep it in good condition.

The latest petrol engines are quite efficient, though, so you should go test one out to see what you think of it.

Hi Ann,

The issue with early PureTech petrol engines is well documented. They use what's called a “wet belt”, which means the timing belt actually runs in oil. Most timing belts do not. Unfortunately, many of these engines have reportedly suffered from premature timing belt degradation. This can lead to lots of other engine issues caused by the presence of bits of the timing belt in the oil system. This did not affect every example of the engine, though.

In an attempt to fix the issue, there was a change to the material used in the timing belt from about 2021.

Aside from that, using the correct oil at service time is key, and perhaps shortening the time between oil services is to be advised. Likewise, we'd urge owners to change the timing belt a little earlier than the official interval.

Hi Kevin,

Looking at the facts first of all, the Grandland Electric and Scenic E-Tech electric start at roughly the same asking price, below €40,000 once all incentives are taken into consideration. However, for that price, the Grandland gets a 73kWh battery pack and an official range of up to 523 kilometres, while the Scenic's 60kWh battery means a range of 430km. The Grandland is more powerful as well, featuring a 213hp motor while a 170hp motor comes with the Scenic's smaller battery.

Nonetheless, that Scenic is a massive 300kg lighter than the Opel so it's actually faster accelerating, better to drive and a little more efficient.

The Scenic can be had with an 87kWh battery to extend the range to an official 625km, though that's more expensive again. On a three-year finance package that may not be an issue of course.

The Scenic is a bit smaller overall, with a length 200mm shy of the Grandland's, but it seems to be better packaged, as the interior is just as spacious and the boot, at 535 litres, is only 15 litres down on the Opel's. The better packaging is likely to do with the fact the Grandland underpinnings were developed to accept engines as well an electric powertrain, while the Scenic is only offered as an EV.

Both feel of good quality inside, though we much rather the infotainment and dashboard layout of the Renault. On the road, we also prefer how the Scenic drives.

Hopefully all that is of help, but don't hesitate to come back to us if you need more.

The best advice we can give you is to go and test drive the cars before you make any decision.

Hi Lorraine,

There really is a lot of choice out there, but we will try to help you narrow things down.

With your car as a trade-in, and the €16,000 budget on top, we'll look for cars up to about €27,000.

First up, narrowing the search to automatic SUVs post-2021 really limits your options to the Nissan Qashqai, which isn't very powerful, the Peugeot 3008 (which is quite rare) or the Skoda Karoq and Volkswagen Tiguan. The latter two are potentially worth a look as they're built on much the same underpinnings as your Ateca and their 2.0 TDI engines have plenty of go. There aren't many of them about with automatic gearboxes though.

Removing the constraint on that opens up the options considerably and one car that stands out for us right away is the Mazda CX-5. It's perhaps not as common as some others, but it's great to drive in particular and it should tick all your other boxes. Try to get hold of one to test drive for yourself.

A newer Ateca is of course an option, and we're big fans of the SEAT, but all the newer ones we found haven't a very powerful engine.

The Peugeot 3008 is another car we like and would encourage you to try it out for size. There are plenty of them about with a manual gearbox.

All of these should have the niceties you're looking for as well.

Come back to us if you need help narrowing your search further, or if you want our opinions on any other alternative to the above.

Hi Michael,

All engines available in the 2021 Optima used timing chains, and they come with no set replacement schedule. In theory they are designed for the life of the engine.

Expert answer

Hi Marie,

I can confirm that those cars' engines do not have wet timing belts - they are traditional 'dry' belts instead. I believe the issues you mentioned relate to Ford's EcoBoost petrol engines only.

Hi Peter,

All the various 2.0-litre engines (TDI diesel and FSI/TFSI petrol) in the 2004 Audi A3 used cam belts.
