FORD AT AARONS AUTOS

What caused this Vacuum pump to fail?

This Ford Fiesta Ecoboost was recovered into us after the customer noticed his oil warning light was staying on whilst the car was still running.

When we got the car into the workshop we always like to give them a quick start just to see if there are any other faults we need to look at whilst stripping it down.

In this case we noticed there was no vacuum assistance for the brakes and after a quick look at the vacuum pump i t became apparent there was a problem.

So, what caused this Vacuum pump to fail?

The rubber debris from the failing wetbelt had traveled through the oil galleries and managed to block the little gauze filter going into the vacuum pump causing it to starve itself of oil.

The engine oil in this particular engine had not been changed regularly and possibly not even been the correct specification oil.

Once we had carried out our wetbelt replacement process which in this case included a new oil pump and replaced the vacuum pump the car ran perfect.

We have recommended the customer has another oil change within 2000 miles just to ensure any rubber particles which we couldn’t remove will be flushed through the system and then removed.
