Suzuki Grand Vitara Engine Problems

Finding the cause of a problem can be challenging, particularly if it is intermittent, or like yours, only when the radio was turned on. You have to pity the mechanic sometimes, but it does highlight the need to be observant when you find a problem. Write down as much information as you can about what happens, when it happens and anything else that might help the mechanic diagnose it.

Many owners of Suzukis of this era are shifting from the original green-coloured coolant to the long-life blue type (believe it or not, engine coolants are broadly identifiable by colour these days). Make sure that whatever brand you buy is borate and silicate-free, as this is important for Japanese engines (European engines, in comparison, need Phosphate-free coolant).

If you’re still unsure, you can buy coolant form a Suzuki dealership spare parts department and know that you’re getting the right product. One other tip; don’t mix coolants. Like oils, coolants are a sophisticated blend of base-product and additives and these formulations, when mixed, can cancel out some of the protection you’re paying for.

There are a number of things it could be. Start by replacing the spark plugs and air cleaner, and clean the throttle body. You could add for fuel system cleaner to the petrol when you fill up, and you could give it a longish hard run to blow out any carbon build-up.

The Suzuki J24B engine in your vehicle has a timing chain and not a timing belt. The chain should be good for the life of the engine provided the engine is serviced correctly.

A chain.
