How to prevent water getting into your Fiat Ducato Injectors

We hear stories of failed injectors in Fiat Ducato Engines. Attempts at removing /extracting them fail usually, because they’ve rusted themselves in very firmly over time.

In many case very expensive remedies are resorted to ( no choice) including replacing the complete head, plus new injectors. That’s a very expensive process.

Why did it happen? Well the problem started a long time before. The Fiat has a scuttle or drain from side to side at the base of the windscreen.

It can get get blocked with leaves and the water can’t run awAy down through the provided drain. The problem is made worse because in the earlier Fiat engines, up to about 2018/2019, the was only the one main drain and from manufacture that was on the left side looking at the cost from the front. Ok in the left hand drive design models.

But in right hand exports the drain stayed on the sand side ( left) and in Australia for example (right hand drive) the road camber falls away to the drivers left as seen driving forward (opposite to European countries).

Since water doesn’t run uphill, the water naturally migrates to the passenger side where (surprise surprise) it can’t get into the provided drain. And it can bank up and run over into the engine compartment.

The other issue is the scuttle against the bottom of the windscreen doesn’t appear to be sealed and with dirt and dust buildup, water runs down the windscreen and into the engine compartment.

Various problems have been documented such as injector bases sitting in dams of water which can’t escape, the heat and cool off starts rust and it gets into the base and rusts. other problems documented in various facebook groups, is that the throttle body gets wet and water seeps in, rusting and finally immobilizing the throttle.

The purpose of this video is to show some ways of preventing the water from getting in in the first place, plus some good helpful tips along the way.
