Holden Barina Problems

That price is towards the top end of things for this particular make and model, but within reason given the low kilometres on the odometer. Make sure it has a full service record as, even though it hasn’t been used much, it will still have needed proper servicing if it’s to remain reliable.

First thoughts are that the stepper-motor (which controls the idle speed) is faulty. That would explain both the high idle at low engine temps and the stalling and stumbling as you roll to a stop. This component is really just a small electric motor and shouldn't be too expensive to replace.

But have the car scanned first to make sure there are no other obvious causes for this behaviour. A faulty engine temperature sensor or some other small component could also produce these symptoms.

This is not a good sign and suggests that you have a fairly major engine problem. Sometimes this can be caused by an automatic transmission’s oil cooler having split and emptying transmission fluid (oil) into the radiator’s coolant. If that’s the case, the transmission will also probably be damaged both mechanically and electronically.

Other causes are a catastrophic failure of the engine crankcase or – not quite as serious – a blown cylinder head gasket. But in either of these cases, the engine will need major repairs. The cost of which may exceed the actual value of the car.

Depending on the severity of the problem, a recycled, second-hand engine from a wrecked Barina of the same model might be a better option.

A manual car that jumps out of gear is usually a case of a worn gearbox. As the internals and gear selectors wear over time, they become loose, allowing the vehicle to jump into neutral.

The first check would be to see that the external linkage to the gearbox (a cable in the Barina’s case) is correctly adjusted and not about to fall apart. If that’s the case, you might find that the selector is not fully engaging each gear, and that’s why it’s jumping out of that gear. But beyond that, the problem is likely to be caused by wear inside the mechanical bits of the transmission.

By 'rides' I’ll assume you mean 'slips', which then slowly allows the car to build up to speed (as in, the rest of the car catches up with the engine). There are two major causes of this, the first is a clutch that is out of adjustment, and the second is a clutch that really needs replacement.

The problem you have, though, is that even if the clutch on the Barina is adjustable (and some clutches aren’t) the fact that you’ve been driving it with the clutch slipping suggests that you’ve already damaged the clutch to the point where it would need to be replaced anyway. Continuing to drive it can also put 'hot-spots' on the car’s flywheel (to which the clutch attaches) and that can mean the flywheel also needs to be resurfaced when you replace the clutch.

I reckon, at the minimum, you’re looking at a new clutch kit. Ignoring it will eventually wind up with the clutch expiring completely and you walking home.

The first thing to determine is whether the engine is actually getting hot. You need to find a mechanic who can tell the difference between a genuinely hot engine and one that is crying wolf. Most times, this will involve letting the engine idle until the warning light comes on and then checking the actual temperature of the coolant. This is usually done via a trusted thermometer (infra-red thermometers are great for this) checking the temperature of the coolant in the radiator's top tank.

If the engine really is hot, then you're looking for a mechanical problem. But if the temperature is within a normal range, then you need to start looking for a dud temperature sensor, faulty gauge/light or a problem with the car's wiring. This can be a lot harder to find than you might think, but driving around with a temperature warning flashing is no good either.

There’s no hard and fast rule on this stuff, and the lifespan of a car will depend heavily on how it’s been serviced. Any car that has been ignored and abused will have a shorter run than the same make and model that has been meticulously maintained and serviced. And this difference can literally be hundreds of thousands of kilometres.

However, it’s also worth keeping in mind that this model Barina was a Daewoo by any other name (and not a particularly good one, at that) and was designed and engineered as such. Even a well maintained example is probably going to be getting pretty long in the tooth by the time 200,000km have been clocked up. Common faults include dramas with the engine and transmission and many owners simply find that the cost of repairs is more than the value of the vehicle itself. At which point they get scrapped and recycled.

It won't be the sump itself disintegrating, but my guess is that somebody who has changed the oil in the past has over-tightened the drain plug when they've replaced it. That stretches the threads on what is often a relatively soft metal and, as a result, the threads have broken away from the rest of the oil pan as you've tightened the plug.

This is actually more common than you think and happens because people don't stop to think about how much force they use when they replace the plug. While it's true that you don't want the plug undoing itself while you're driving, it's also the case that all that sump plug has to do is keep the oil inside the engine. It serves no other purpose and simply doesn't need to be too tight. Sometimes, home mechanics ignore the need to replace the crush washer on this plug with the result that they then notice an oil a leak a few days later. That's when they'll reach for the big spanner and try to tighten the sump plug some more to stop the leak. And that's when the threads break away and they're in the position you now find yourself.

The solution is to get the vehicle to a workshop (you may have to tow it as it can't be driven with no oil in the engine) which should be able to drill the hole in the sump to the next over-size and fit a slightly larger, new sump plug. It's tricky though, as you don't want to allow swarf (little metal filings from the drilling process) into the engine where they'll damage those expensive internal parts.

From what I can gather, the engine in your Barina is an interference design. That is, if the timing belt breaks, the pistons and valves (in the cylinder head) will, indeed, meet head on at speed, turning the engine to junk in a slip-second. So make sure the timing belt is changed every 100,000km to reduce the risk of this happening.

Some engines with timing belts are non-interference designs, meaning that a broken belt will simply allow the pistons and crankshaft to continue to rotate without hitting (or damaging) the valves. Replacing the belt and retiming the engine will return it to full health. You'll still be stranded by the roadside if it happens, of course.

First things first: If you can smell coolant when the engine is warmed up (or any other time) then you have a leak somewhere. Coolant leaks can be hard to spot as they are not always large and are often located in weird, hard to see places. But if you can smell it, it’s escaping the cooling system somewhere and you need to locate it and fix it.

If you have a slow leak, it’s possible you could drive for weeks without the car overheating, but eventually the engine will start to notice the low coolant level and run hotter as a result. Get it fixed now before you damage the engine. You should be fine to use a bit of tap-water (which will dilute the coolant in the rest of the system) until the leak is found, but don’t leave tap-water (or an incorrect or diluted mixture of water and coolant) in the radiator for the long term.

As for the brakes, the problem does, indeed, sound like warped rotors. Sometimes these can be machined back to true, but often they need to be replaced. Either way, replacing the brake pads at the same time is best practice. Worn pads on new rotors can make those nice, new rotors wear faster than they should.
