Sr180- D4D Head Gasket Issues?

[NickSw]

Recently I've read on here of head gasket failures particularly with the D4D engined SR180.

Wifes car is an '08 SR 180. About 57k miles (I think) and regularly serviced by Toyota main agent.

Is there a particular cause for this gasket failure. I presume overheating caused by some failure in the cooling system and I guess the most likely culprit would be the water pump.

Touching wood very firmly, her car has not suffered any such problem.

Is there anything I can do to ensure it does not befall such a failure?

Thanks,

Nick.

Thanks very much for the link to CharlieFarlie's excellent guide.

This gives the symptoms and possible cures very clearly. I still would like to know the possible cause(s).

As Toyota are offering extended warranty engine repair/replacement, my sceptical old grey cells wonder if this is an inherent fault in the design of the engine.

Again touching wood firmly, swmbo's car is not suffering any symptoms. As a retired engineer, and self-retired motorist, knowing the cause(s) of such problems wold be of interest to me.

Thanks again,

Nick.
