710 cap -rant

Checked the oil last night, and it was a bit low, so I decided to add some. Grabbed the oils fill cap, and turned to the left. It turned and clicked, and turned and clicked but didn't come off. WTF? Maybe it's like a medicine bottle and you have to push down, push turn click, push turn click, no go. Am I turning it the wrong way? turn the other way, and the same result. WTF? So I decide to use brut force, grap the cap and pull. Half of it come off. It turns out the cap is made in two peices, so you can't overtighten it(HAH!). I was then able to get the channel-locks on the remaining part to get it off to add the oil. What a stupid design.

Probably the same person who designed the 710 cap also designed the coolant engine plug on the 4.0L. What a stupid design. Who comes up with a plug where you have to use a 5/16" square tool, that doesn't exist. I tried to use some steel key stock, but it started to fail, so I had to give up on it before it broke off and got stuck inside the plug. Idiots.

It's actually an 8m/m square drive - which does exist (same plug drive is used on the Peugeot BA-10/5.)

A tool can be readily improvised using an 8m/m or 5/16" hex key and a grinding wheel in a few minutes' time. It's a leftover influence of Renault - but if it takes a standard thread (I'm informed that it's likely 3/8" NPT,) then it can be replaced with a standard plug and ditched.)

The "ratcheting" plugs are asinine - last time I drove through Oregon, I told the pump jockey to "only click the cap once." When I filled up again in NorCal, the damned cap came off in my hand, and I had to grab the bottom part with the edge of a blade to turn it. (I can understand why disabled people would like the "service" being offered - but I want the option to refuse if I prefer to do it myself!)

Yes, if you have a grinder. I don't, so I bought some steel key stock - not strong enough. I wonder if these car designers sit around just thinking up 5 or 6 things on your car that are designed to really screw with the car owner - things that require tools that you can't find or have to make yourself. I stand by my previous thought.......Idiots.

they make interesting fastener drive styles simply so that people who shouldn't be taking these things apart, can't. especially not with their basic wal-mart ratchet set.

although torx does make sense from an engineering stand point(more drive engagement from your tools, though most people screw up the insertion of the tooling)

Removing torx bolts is what Jeepers do if they go to Hell.
