Question about 1990 Isuzu Trooper
I have the 4 cyl (2.6) 5 speed. The hose that leads from the back of the thermostat housing and disappears under the fuel injection chamber is leaking. I can see where it goes from there. The repair shop wants $200 to replace a heater(?) hose. I can see where the hose connects to the back side of the thermostat housing but it goes down into the abyss. I tried looking from underneath looking up but still cant see where it goes. Does anyone know where this hose leads. If I could see or find out where it leads I could locate the bottom connection and replace it. HELP !!!
The hose is a cooling by-pass hose. It makes a big horseshoe and attaches under the front of the intake maniold. I think that if you have small hands and a lot of patience you can likely replace it without haveing to take half the engine apart. (You have to pull the head to pull the intake manifold).
I think if you remove the battery, and have a small bright light you will be able to see where if attaches under the front of the intake manifold. Advance auto sells the by -pass hose for
around $12.00 I think.
Becare if you are probing around there are way too many vaccum lines under the manifold.
If they come off and you don't know where to put them -- you are in deep kim chee. I know I am
in super deep Kim chee now.
Hope this helps
