Hi guys,

I just bought a 2002 Volvo S40 1.9T second hand, but I keep wondering why my Turbo hose begin squeeze when I give throttle a hard press (suddenly) but if I press the throttle slowly (from idle to 4k rpm), there's nothing happen with the hose. Is it normal ??? plz tell me what should I do.

This is the hose that i'm talking about (the "U" turn hose)




thx before for any advices ..........

warm regards

ermen

 

Does the hose feel really soft?

 

not really that "soft", but i can squeeze it with my bare hand.

is it normal or i have to replace it ?

 

It should usually be pretty stiff. If the air filter is clean it should not in any way collapse under acceleration.

 

that's not Air Intake Hose and my Air Filter in good condition (considering i'm replace it approx 2 month ago).

here it is the full engine trunk, I can't describe what function of those hose

 

The Crome looking hose goes from the turbo to the intercooler on the bottom. Then the top rubber hose goes from the top of the intercooler to the throttle body. When you open full throttle the suction of the motor is what collapses the hose.

 

that's mean normal condition ?

OMG, btw i really really love your T5-R ......... [8D] it's rare item here (Indonesia)

 

Well the hose should not collapse. That is setup like normal I think the hose is just old and to soft. Or there is a restriction somewhere.

Thanks yes it is a rare item here as well since there was only 185 brought to the U.S.

 

ok alan, thanks a lot, but now i'm thinking about to replace it with stainless or galvanize material, is it ok ? remember the prices from couples store i looked for [X(], i prefer to replace it with other material and it cost me less than the original rubber.

hey dude, are you seriosly ? there are only around 185 pcs in US ??? that's great thing then.

 

Yes only 185.

You can make it out of something else and cut sections off that one to use as the connector between what you make it with and the throttle body and intercooler.

 

well, i find out with other material then. wait for my report about 2 days later. I really stress with this thing since X-mas.

btw, Happy New Year, bro .......

 

I will wait to hear back.

Happy New Year to you as well!!

 

hi alan,

the mechanic said, the hose should be fine, the problem is turbo propeller that not work properly. is it true? he said that i not to hurry to change the hose, but i'm not sure enough with his says. what do you think?

:d

 

To tell you for sure I would have to feel the turbo for myself.
If you still feel boost then the turbo should be fine. If it was locked up it would have less power than a regular 4 cylinder with no turbo.
