Used Daihatsu Sirion review: 1998-2005
By Ewan Kennedy · 19 Apr 2013
Daihatsu Sirion is a well-built Japanese car with an excellent reputation for reliability and low running costs. It wasn’t as successful as big brother Daihatsu Charade.So there are some bargains in Daihatsu Sirions as they are regarded as orphans and have suffered in resale value because of this. Despite this they can be kept on the road with a minimum of expense if you choose a good one and look after it correctly.A new Daihatsu Sirion released in April 2002 was more of a facelift, and although longer and given a freshened face, did not offer anything different in the way of drivetrain. For that we had to wait until the all-new Sirion launched here 2005 -- infortunately not long before Daihatsu exited the Australian market altogether. It was substantially bigger than the first-generation model that was launched in Australia in 1998. There’s decent interior room and a boot that can handle a fair amount of luggage. The older models are smaller and probably best left to couples and singles, but the 2005 model can work as a family car if the children are in their pre-teen stage.Daihatsu Sirion is well equipped, coming with air conditioning, a four-speaker CD stereo, power door mirrors, lap-sash safety belts in all five seats and dual airbags. A model worth chasing down is the Sirion Sport, with alloy wheels, a front body kit that includes foglights, a sportier design of rear lights, colour-coded door handles and ABS brakes it provides a lot of small car for a pretty reasonable price.The first series Daihatsu Sirion used an interesting three-cylinder 1.0-litre engine of the type the Japanese marque had made famous for many years. It continued with the larger model of 2002, but in the 2005 Sirion power came from a more conventional four-cylinder, twin-cam unit displacing 1.3 litres. The latter produced a relatively modest 64 kilowatts, but variable valve timing meant it has strong torque throughout most of the rev range, peaking at 120 Nm at a reasonably low 3200 rpm.Transmission choices are five-speed manual and four-speed automatics. Autos don’t take as much out of the performance as you might expect as the Sirion is relatively light. But our gearbox of choice would be the manual unless you’re doing a lot of commuting in traffic. The manual’s gearshift is light and easy so it’s not a hardship to do your own shifting.Handling is competent without being in any way exciting – definitely not a car for the enthusiast. There’s a reasonably neutral feel at everyday road speeds, but understeer comes in too early. A good set of tyres can give it a better feel and provide grip.Daihatsu has been controlled by Toyota since the early 2000s after getting into financial trouble. Toyota Australian stocks spare parts for most models younger than about 10 years. Check with your local dealer and/or check out parts recyclers in your neighbourhood.As it’s a relatively small car the Sirion doesn’t have a lot of underbonnet space so can be annoying to work on. Workshop manuals are available and are recommended. Don’t tackle any safety related items unless you’re an expert.Insurance costs are generally towards the bottom end of the scale and we don’t know of any major company that charges extra for the Sirion Sport, probably because it’s a dress-up variant not a real sporty design.WHAT TO LOOK FORLook for sun damage on the dash top and rear shelf. Check for tears in the seats and damage to floor and boot mats.Rust is rare but if it does get a hold it can run through very quickly due to the light construction of the Sirion. Look in the lower body areas, as well as the doors and hatchback. The corners of these panels are usually the first to suffer. Check the floor of the cabin and the boot for rust. Repairs there can be expensive.Look for signs of crash repairs, minor repairs correctly executed are to be expected in older cars that spend a lot of time in city/suburban driving, but if you think a Sirion has been in a major crash have it inspected by a professional as sub-standard cars can be dangerous.The engine should start quickly even when cold and should have a relatively smooth idle from start-up. Four-cylinder engines are smoother than the threes.Check there is no smoke from the exhaust tailpipe when the engine is accelerated hard after idling for a while. Gearchanges should all be light and easy, with the clutch taking very little effort to operate.If the gearbox baulks or crunches when you do a fast change down, there could be expensive troubles. The third to second change is usually the first to suffer. If the clutch is heavy or sticks during its movement it could be due for an overhaul.Drive the car at low speed with the steering on full lock in one direction and then the other and listen for a clicking sound of worn universal joints.CAR BUYING TIPBuying an ‘orphan’, a car that’s no longer imported, can save you money. But do your homework on parts and knowledgeable mechanics before getting in too deep.

Best second hand 5-door car for $8000?
Answered by Graham Smith · 14 Nov 2014

You could look at all small models from the mainstream carmakers, like Mazda, and you won’t go wrong. The Mazda2 is a good choice, but you could also look at the Toyota Yaris, Hyundai i20 and Kia Rio.

Ask Smithy Xtra noisy Daihatsu Sirion
Answered by Carsguide.com.au · 19 Jul 2011

What the mechanic told you is rubbish, there has clearly been a change in the way the engine is running, and that suggests there’s a problem. Changing the spark plugs, they’re located in the cylinder head, and the spark leads is a good idea. If you’re not sure take the car to an auto store and they will show you the plugs and leads and supply you with replacements.

If the engine mounts are indeed in good condition (and it can be hard to tell just by looking) then you might be looking at a problem with the idle speed settings. Engines typically idle more slowly when they’re cold and in gear and there’s usually a compensation for this. In an electronically controlled engine like the Sirion’s, this idle-up function will be a job for the onboard computer. But if the computer has lost the plot or isn’t getting the right signal from, say, a temperature sensor, then it can’t bump the idle up a fraction when it needs to. And then, once warmed up, the engine seems normal.

A cold engine that spits a little water out the tailpipe is completely normal. Water is one of the by-products of the combustion process. It’s black because it mixes with soot in the exhaust system. But we only see it when the engine is cold, as once warmed up, the exhaust system turns the water to steam and we don’t see it. A black exhaust in a modern car that runs on ULP is completely normal also.

Daihatsu Sirion clutch wear?
Answered by Carsguide.com.au · 26 Sep 2014

It’s not possible to say with any certainty when your clutch might we worn out, but you’re already doing well having clocked up 105,000 km. You can normally tell how far the clutch has worn by the height of the clutch pedal at take-up. If it’s close to the floor there’s plenty left in it, if it’s at the top of the pedal travel it’s probably getting close to worn out.

What happened to temperature gauges?
Answered by Graham Smith · 20 Mar 2015

I think you can safely assume that it's cost cutting, but it's probably a reflection of today's drivers who rarely look at their gauges anyway and wouldn't know what a temperature is trying to tell them. I too prefer a gauge as you see what's happening before it gets to the point of serious damage to the engine, but the red light if observed and acted upon should provide sufficient warning of trouble. Like you I also believe a tachometer is a not needed in most cars.

If the ABS and overall braking system is working properly, then the warning light you’re seeing is probably being caused by a sensor or part of the electrical circuit involved in controlling the ABS. An electronic scan of the car’s on-board computer should give you an insight into what’s wrong and you can work forward from there. Simply replacing bits and pieces in the hope that they fix the problem is often a very time and money consuming way to go about this. Most workshops will be able to scan the car and interpret the fault codes.

How to check if my 2000 Daihatsu Sirion's timing is right
Answered by David Morley · 17 Jan 2024

Assuming you mean the Daihatsu's ignition timing, the on-board computer should control the timing. If this is out of whack, you'll find the car could be difficult to start, will idle poorly, use more fuel than it should, be down on power and may even overheat. Or all of those things. For reference, the correct timing for this engine is five degrees before top dead centre (+ or – two degrees) at idle. It can be checked by a workshop to verify whether it's correct or not.

If you're referring to the engine's valve timing, that's a different thing altogether. You need to reset the valve timing whenever you change the rubber toothed timing belt to avoid catastrophic damage to the engine. The valve timing of the car should not change between belt-change intervals, but if it has, then the damage has probably already been done. Again, for reference, the two camshafts need to be lined up with their respective timing marks, along with the crankshaft in its correct position before the new belt is fitted. This is not a simple job for a Saturday morning in the driveway.

Unlike fuel and oil filters which are often located in easily accessible places and are able to be removed and replaced easily, most automatic transmission filters are located inside the actual transmission. Usually, this means removing the transmission's pan which is also usually the way to access the transmission's valve body and other parts that are part of a transmission service.

The best way to access this area is to have the car on a hoist and work from underneath.
