The only vacuum line you need connected is the one that goes from the back of the alternator to the brake booster. The other line that is nice but not necessary, is from the intercooler to the top of the injection pump. The rest of the vacuum is for the two valves that are involved with the cold start up of the vehicle, and the AC.

I have isuzu bighorn '92 model automatic,there is a leaking oil under the intercooler turbo...is this normal?thanks.


Leaking of any fluid is not normal. The only time any fluid should expel from the car is if you have overfilled something. Your turbo could need replacing, you could have a hole in the intercooler. Have you noticed any lack of performance or extra smoke...

My 1991 isuzu trooper has no power on hilss


Hi Patrick, Definitely check the timing and also the fuel pump pressure. Make sure to replace the air filter. Check all the vacuum hoses for leakage and good fit. Make sure no pipes are damaged or broken. Make sure the ducting between the airflow sensor and the throttle body is intact and not cracked or broken. I believe the problem is in the ducting and the vehicle is sucking in air. Regards John

Hi all, Just got me an old ( 1991) Trooper 2.8 TDI (UBS55). I ordered, but am still waiting for my maintenance manual. Small things need doing up. Like the rubber fuel filling hose between filler neck and...


Hello Hans. A protector is what you have. Something strange about the dealer giving you this because if what you asked for was a filler hose then why did they give you a hose protector. Go back with because what you asked for was correct no other name for it. Hose is hose. Hope you kept the receipt if so they gotta change it for you. Cheers

My Trooper UBS55 2,8 TDI need topping up with steering oil. The filler cap states only to use DOT 3 oil. However the only bottle with DOT 3 oil I can find states that this is brake and clutch fluid. Is it...


No, do not use clutch or brake fluid in your steering.

ATF used to be used in Power Steering many Years ago, but it is very high in detergents where Modern Power Steering fluid is not so .

If you can get the correct power steering fluid this would be best (consult your owners manual),but I have seen some customers that have use ATF in there steering for years will no ill effect, but I wouldn't advise it.

Please leave fair comment if I have helped you.

Thanks

On my isuzu bighorn/trooper 3.1 TD ,how does the buterfly valve in exhaust work in with the switch -(with a engine on it) and the valve on inlet to intercooler,


Hi , the switch in the car puts the flap in the exhaust over for quick warm up and the flap in the inlet manifold is part of the ERG setup.The ERG flap works with the ECU and also when you hit the warm up switch .
