Holden Rodeo 2000 Problems

THAT'S about right for the V6 Rodeo, I'm afraid. Apart from converting it to dual-fuel, the only things you can do are to ensure the wheel alignment is OK; the tyres in good condition and inflated to the recommended pressure or slightly higher; and ladder racks and other items affecting the aerodynamics are removed.

It’s very likely you have at least two distinct things going on here. While it’s not uncommon for the contents of a car’s radiator to appear murky or dirty, that’s not usually something that would trigger a check engine light. If the radiator is filled with tap water (not a good thing) then it can soon become rusty and dirty to the eye. It will still cool the engine, but you’re much better off with the correct type and grade of coolant to protect the engine from corrosion.

As far as the check engine light goes, you could be looking at literally hundreds of causes for this. The check engine light is telling you that something is not quite right and that you should have the car scanned at a workshop. That way, the computer can tell the mechanic exactly what’s going on and what needs to be checked, repaired or replaced. Until you do that, you’re effectively flying blind.

People often complain about the complexities of modern cars, but the ability to plug a diagnostic probe into a car and have the vehicle tell you what’s wrong with it is, indeed, worthwhile progress.
