Take your socket set and try various sockets until you find one that fits...then look at the size on the side of socket...BINGO!!! now you know the size.
The socket size for the oil drain plug on a 1998 Isuzu Trooper with a 6-cylinder engine is typically 17mm. It's always a good practice to verify this with a socket or wrench set, as variations can occur based on maintenance history or previous repairs.
At the bottom of the engine oil pan.
Look at the bottom or rear side of the radiator
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.
Should be on the bottom passenger side of the radiator, facing the engine...That's where mine is...
it is on the transmission pan...you have two....its the highest one....the other is a drain plug...
Remove the drain bolt from the oil pan, and let the oil drain into a bucket. Unscrew the oil filter with the use of a filter wrench. Screw the new filter on, and reinstall the oil bolt.
There is a drain plug on the bottom of the transmission. To fill it, there is a plug toward the top of the transmission case where U have to pump the new fluid in till it starts to drain out.. There is no fill or trans. dipstick in top.
probably doesn't have one, I have yet to see that on any car. You have to use as much as you can then drop it or siphon thru fill tube
there is a drain plug and a fill plug on the underside of the transmission. you need to use the fill plug. You can not fill the transmission fluid or check the level, any other way.(it is a ridiculous design, i know.....) go to autozone.com look under Isuzu repair info, then choose the year and choose "trooper".then look under "fluids" the info will be there.

To change the radiator on a 1999 Isuzu Trooper, first disconnect the negative battery terminal and drain the coolant by opening the drain valve at the bottom of the radiator. Remove the upper and lower radiator hoses, as well as any attached clamps and electrical connections. Unscrew the mounting bolts that secure the radiator to the support brackets, then carefully lift it out. Install the new radiator by reversing the removal steps, ensuring all connections are secure before refilling the coolant and checking for leaks.
