4G64 head bolts

[xj0hnx]

Does anyone know the right size for the DSM 4G64 head bolts "Triple Hex" socket? I got one from Autozone that was a SAE/Metric (whatever idiot came up with that idea needs to be shot since they are different) and it was just a hair too big, duh the next smaller size was too small.

It's a 2003 ,I think, GS, they are the OEM head studs as far as I know. I am pulling the head for a friend because it's overheating, and they have already done everything short of head gasket, and checking if the head is warped. They just bought it from a guy, but it doesn't look like it has ever been taken apart. I put a 13mm on one and it felt tight, I turned it and I felt it pop over the head, so I wiped some oil off and looked closer and saw they are the triple hex.

Looks just like this one ...

Passenger side, tranny on drivers side. Yip SOHC, 2.4L.

Wow, that's crazy, since the 12MM was too small. I guess it makes some kind of sense, since the 13MM fit very tight, but still skipped teeth.

Thank you.

M11x1.125 is the bolt size and thread pitch. you need to know what socket size you need to fit the head right? my suggestion would be to get a set of metric and a set of sae 12pt sockets, or borrow them..

Going to make a cast of it, and measurements and take it to a specialty tool shop today, hopefully they will have a socket that fits, they seem to have ...everything. If they don't than I guess we can take the cast and make a socket. I even called Mitsubishi here and they didn't know.

Alrighty, found it. Snap-On has a 12-point 12mm shallow splined socket that fits perfectly.

SWM121A, Socket, Metric, Shallow, 12 mm, 12-Point

If you need to take the head off a 4G64 engine, maybe other Mitsubishi's, this is the socket for you.

Alright, how do you loosen the timing belt on this motor? I watched a video of the 2006, and there's a lever you push and it slacks the belt, but this car doesn't have that lever.

Anyone know how to loosen it?
