• My 2007 Toyota LandCruiser is using a lot of coolant

  Coolant leaks can be very tricky things, often starting at one point and then running down a hose, bracket or wire to drop on the ground where you’re not looking for them. If you definitely can’t find a leak, however, you need to start looking for another problem which could even be a leaking head gasket which is allowing the coolant to enter the engine’s cylinders.

  The first thing I’d do, however, is change the radiator hoses., If they’re flattening out when the engine is running, that suggests they’ve collapsed internally and are unable to cope with the suction created by the engine’s water pump (which circulates the coolant around the engine). Even if the hoses look fine, they can be damaged inside and, left this way, can cause a blockage in the cooling system which can lead to the engine overheating. Perhaps this is already happening, and allowing the boiling coolant to escape the system via the pressurised radiator cap or the overflow system.

• Why is the RAV4's 2.5 litre engine more economical than the 2.0 litre?

  It all sounds a bit counter-intuitive, doesn’t it: That a smaller engine could use more fuel thana larger one? But, in fact, it’s all down to the hybrid driveline in the 2.5-litre version of the RAV4. Because the hybrid version also has an electric motor to help propel the vehicle, the petrol engine has less work to do. So, it uses less fuel, particularly on the official test cycle that determines these numbers.

  In fact, in the hybrid RAV4, the petrol engine isn’t even running a lot of the time, especially in stop-start traffic. The electric motor can draw from the batteries on board to get the vehicle rolling, and when it’s slowing down, the electric motor recharges those batteries for the next green light. And when the car is running on electric power, it’s not using any petrol at all.

  By contrast, the non-hybrid RAV4 is running its petrol engine the whole time (apart from when it’s at a complete standstill). And that, in a nutshell, is how a bigger engine can use less fuel than a smaller one in the same make and model.

• My 1997 Toyota Prado GX will crank but not start

  Before you buy more parts that may or may not fix the problem, have the vehicle electronically scanned. This is by far the most cost-effective way of finding out what’s wrong and then being able to tackle the actual problem. You could spend weeks and months, not to mention hundreds and thousands of dollars, replacing random parts that have no relationship to what’s causing the engine to refuse to start.

  There are literally thousands of reasons for the symptoms you’ve noted, so try to finding the root cause before committing to more replacement bits and pieces.
