will a little pressure ruin the vacuum system?

Hi everyone.

i'm a brand new member here so thank you for having me. especially a big thank you to Martin for his wise advice yesterday.

i am about to purchase my first jimny in a couple of days time knowing that it has a 4wd problem in that it will not engage 4wd high or low and there is a permanent flashing green symbol on the instrument panel ( twice a second ) that remains on even when restarting the car ( 06 plate but it's very low mileage and full history etc so i'm not overly concerned. )

my question to you all is: would it do any damage if i slightly pressurise the vacuum system in order to search for any leaks using soapy water?

thank you all in advance. .

Already answered by Martin, I plan to do the same if my system ever fails.
So only thing left is to say hello.
Mike

Please let us know how you get on. I'd always though that a bit of pressure would be an easy way to find a leak, but in my 7 years of Jimny ownership I haven't yet had an opportunity to try it!

I actually bought a 2002 Jimny a month ago that has the piping to engage the 4wd completely rusted out.

I bought the parts and the dealership advice me also to change the seals on the front hubs, so I am quite interesting in know how it works for you before opening the hubs.

Thanks Martin.

That’s great news.. will hopefully make tracking it down a lot easier.

Thanks guys..

I’ll keep you posted as to how successful it is over the next coupe of weeks.!
