Find your ac compressor. Follow the larger hose. Up to the metering device outlet, that's your low pressure side.
The thermostat on a 1998 Isuzu Trooper is located on the front of the motor. It is in the top radiator hose where it connects to the motor. To access the thermostat, the hose needs to be disconnected from the motor.
The thermostat on a 2000 Isuzu Trooper is located on top of the engine, below the upper radiator hose. It controls the flow of coolant to the radiator and throughout the vehicle.
If a smog inspector said that the EGR EVAP and Fuel Pressure sensor are modified on a 1988 Isuzu Trooper II 2.6, then the problem has to be fixed before the smog inspector will approve the vehicle for registration. The EGR EVAP and Fuel Pressure Sensors have to be put back the way they came from the factory.

located below power pack at front of motor hose from bottom of radiator connected to it
if it is a 3ltr diesel follow the top hose to the engine and that the housing for the thermostate
Under the water neck, where the upper radiator hose to connected to the intake manifold on top of the engine.
I believe that it's just above the Front Right spark plug coil. It has a vacuum hose attached to it.
Unscrew a hose at the lowest point, and drain the fluid into a pail. Remove and replace the lines one at a time, making sure to route the new lines the same.
My guess, after a quick look, is to remove the hose clamp where the fill hose empties into the tank and siphon from there. I ended up here because I was looking for a way to bypass the anti-siphon block. Kevin
I found it on 91 V6 under air cleaner on front of the intake manifold. look around the upper radiator hose
There should be a drain on the bottom of the radiator somewhere. If you cannot find one, then remove the lower radiator hose and drain the coolant form that location.
