6G72 Sump Plug Size

Post by WeeMagna »

Hi everyone,

Does anyone know what the M x mm size is for a 6G72 sump plug?...Oh and the length too.

I am fed up with the original. It has a 24mm head and it's just to thin to get a spanner on. It's alright if you have a lift and can get the car to head height. But having to lay on the ground is just bloody ridiculous. Looks like once again I have to put the car on ramps just to loosen the plug, then take it off the ramps to drain the oil.

I want to change it to a smaller and thicker head.

Thank for the help.

Doesn't sound right. I just ordered 4 genuine sump plugs, all 17mm heads (quite deep) and I can get to it with a spanner under the car not even on ramps!
Sure that's an OEM one? I have used non genuine plugs before that sound similar to that, oddball 24/2527mm head size and awful to use under the car

Hi WeeMagna,

Went through the same drama mate, simply go into any mitsubishi dealer and get a Mitsubishi 380 Sump Plug.

Perfect fit and will solve ALL your issues!

Cheers
Dean

Edit: Mine was 6G74 but should be same I am pretty certain.

Thanks TuffTR,

17MM with deep heads sound good to me...I ended up finding a 15/16 socket (pretty much close enough to 24mm) and put it on a breaker bar. But even then I had to jack the old Magna up quite a bit to get the angle...and remove the wheel to hold the socket on.

Maybe it is not OEM...I don't know. But yeah, it seems odd to have a 24mm head with such a shallow depth. It is only about 5mm, so any 24mm spanner will just slip off.

I like to change my oil every 10K. I just got to about 8k and thought, the sun is shining and the beer is cold...Oil change...and things then went pear shaped and memories of the last oil change came flooding back....

I am house sitting and don't have my "normal" tools with me. Using a tape measure I measure M12. The shaft is about 15mm. But I have no idea of the thread size. It could be any thing from 1.25 to 1.75.

Thanks again...I now know that it might not be the proper part.

Cheers
Neil

Thanks Dean,

I knew the 380 would be good for something....:)

I am not sure if the 6G74 is the same as the 6G72...and I would rather not be sitting in some ones driveway with an empty sump waiting to find out.

Thanks for the tip and I will certainly look into it...Cheers Mate

Regards
Neil

Just to be sure are you talking of the 6g72 from.a 2nd Gen magna or 6g72 from a 3rd Gen?

If its from a 2nd Gen then its 21mm and if my memory serves me correctly its bigger than the 6g72 from a 3rd Gen which i believe is 17mm.

I will try checking the service manuals when i get 5mins to be sure.

Thanks Dougal,

It is a 3rd gen. 98 TF exec.

It says nothing about it in the Gregory's.

Supercheap have 3 or 4 M12 plugs listed all with different thread pitch and length. When I do a model search, they offer two plugs one with no specs and the other is M14.

I would have thought a simple thing like a sump plug would have been a ... simple thing.

I just got back from Supercheap.

I got one that looks right. It has a 17mm head.

The packet says "the intelligent drain plug". It also says on the pack that it is M14 x 1.5...I said to the bloke, that is not M14 it looks like M12, and he agreed. I have now measured it twice and it IS M12.

That is very intelligent of them to label it 14 when in fact it is 12. No wonder it has been so confusing.

might be worth fitting a Fumoto drain plug - simply open the tap and oil comes out.

Thanks for the thought, but I will give it a miss...

You are right thou...Open the tap and oil comes out...nothing else just oil ! So a lot of the crap you are trying to remove, stays there.

I would rather have a proper and removable drain plug that allows all the oil and the crap to drain out freely.

Thanks Tufftr,

That looks just like the one I got from Supercheap, but mine is the type with the O ring.

Cheers.
