Well the oil pan is on the bottom of the engine, and the bolt is on the very bottom of the pan.
Here's a picture, and you can somewhat make out the bolt.
You can use either type of wrench, though using a socket will reduce the chance of rounding the bolt head.Where is oil pan/oil plug on 97 jeep wrangler?
Go to the passenger side of the jeep, from behind the front tire if you look directly under the engine you will see a black pan with a bolt plug on the side of the pan toward the bottom of the side. If you find it and you aren't sure if you really have it, the muffler pipe and then the oil filter are pretty much on top of it. When you change your filter excess oil usually spills from it and you don't even have to move you're oil bucket cause it's right over where the plug is anyway, just wipe the oil of the muffler or it'll burn and smell.Where is oil pan/oil plug on 97 jeep wrangler?
The oil drain plug is shown in the write up here. The write up is for a newer model 4.0L that doesn't have a distributor cap like the older 4.0L.
You can use an adjustable as the drain shouldn't be fitted too tightly. I normally use a ring spanner, 5/8 inch I think it is.
One thing I must comment on is step 5 where it says about removing the oil filler cap. The oil filler cap on TJs can be stubborn to remove when the engine is hot and can break in two leaving the threaded part in the rocker cover. You then need to use grips to hold and turn the threaded section of cap out.
What I'd do is loosen the filler cap when the engine is cold and turn it back on so it just stops before warming the engine. It will come off easily then after the engine is warmed up.
I learnt this AFTER breaking the cap on my 97 TJ.
When fitting a new oil filter instead of using a little oil to wet the seal I use a little grease smeared over the seal. I find it makes the filters easier to remove at oil changes.Where is oil pan/oil plug on 97 jeep wrangler?
most every oil pan plug will be on the bottom of all oil pans, and there won't be any other bolts there.
think about it . when changing the oil, all the oil has to come (drain) to the bottom of the pan. if it didn't you would always be letting some dirty oil remain in the engine. always make sure the oil is hot before you drain it. more will come out when it's hot. don't forget to replace the oil filter every time you change your oil. usually 3,000 to 4,000 miles.you'll want to get what they call an oil filter wrench for that. when you buy the oil and filter ask about the wrench. shouldn't be over $5.00 i believe for the wrench.Where is oil pan/oil plug on 97 jeep wrangler?
There is only 1 bolt in the general area on a TJ but on my CJ the transmission drain plug is about 4 inches away.
