Ford Courier Engine Problems

It’s not likely to be an ongoing problem once you repair or replace the radiator, assuming that is the problem. I would check for other issues, like a blown radiator hose or clamp. There are no other major issues with the Courier that you need to be concerned with, but you do need to understand that it is an old vehicle and old vehicles can break down.

The rule of thumb is that a vehicle would use around 20 per cent more LPG than it would use of running on petrol. On average a 1996 Ford Courier would do around 12.5L/100 km on petrol, which means it should do around 15L/100 km, or 6.6km/litre, on gas. On that basis yours is thirsty. On your second question, yes you would expect a car with fuel injection to be more economical than one with a carburetor.
