Holden Barina 2015 FAQs

Check out real-world situations relating to the Holden Barina 2015 here, particularly what our experts have to say about them.

• Why can I smell coolant burning when my 2015 Holden Barina gets hot?

  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.

• Oil is mixing with coolant in my 2015 Holden Barina

  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.
