In my 93 Isuzu Rodeo you have to add your transmission fluid buy poring it into the the transmission fluid dipstick.
The thermostat is inside of the top radiator hose inlet on top of the engine. The hose and the housing will have to be removed to access the housing.
If a 1996 Isuzu Oasis 22 does not have fire to the plugs after changing the timing belt, perhaps a spark plug wire got crossed when hooking up the spark plug wires. Check the coil to make sure the right firing order is being used. Check to make sure the distributor did not accidentally get turned when changing the distributor cap. Also, check the wires to the distributor.
I would visit the automotive car repair wiki, which has a database of OBD2 locations for all vehicles. In your case for a 98 its on the passenger side rather than the driver side like most vehicles. See photo below. http://www.fixexpert.com/obd2/data/honda/odyssey/1998.jpg If you wish to look up others OBDII port locations for other vehicles try the main link at: http://www.fixexpert.com/wiki/OBD-2+Location Good Luck.
The srs light indicates a problem with the airbag system.
the trooper has no dipstick for trans its a sealed system on the trans pan you will find a fill plug and a drain plug the one on top inrecess is the one your looking for with the truck in park running remove fill plug fluid level should be just below that hole you can use ur finger to tell
Remove the cam shaft, then you will hav access to the spark plugs, u can then change them. In terms of changing the oil, its a standard procedure, empty the oil tank frm the cap under the car, wait for it to drain completly, check the dipstick, if it reads empty, your all good!! Simply top it up with new oil and ur away :)
