RAPID POWER 70 SERIES SEALED ALTERNATOR

Toyota parts have an excellent reputation for quality and reliability. In the case of the 70 Series range of V8 diesel LandCruisers, it’s not the quality of the alternator that’s an issue; it’s the location.

Like most, the 70 Series LandCruiser OEM alternator is air-cooled. The issue is that they are vulnerable to water, dust and especially mud.

In the 70 Series, it’s exacerbated; the alternators are at the very bottom of the engine bay. It’s a location that makes them more susceptible to contamination and failure than most 4x4s, but it also makes it difficult to clean them in the field.

Additionally, at some point, cleaning may not work, which would leave your vehicle without power and these days no power means no drive.
