Where does this rubber ring from head gasket kit go. I don’t have and never saw an old one. Also can’t find a new gasket for the chain adjuster service cover. Manual says replace. Has anyone got a part number for it. Old one is aluminium I think

Could it be the oil cooler seal? I don't think so but it looks similar in size. I am rebuilding my G6 now, but haven't seen that one yet. I will dig around and see if I can see one like it.

Probably the O-ring at the back of the water pump, where the metal coolant pipe connects to it.

The chain tensioner adjustment cover gasket is Mazda part number:

G60110512A

You can just make one from some Felpro gasket sheet material and it will work fine.......I have done this several times. Use a small amount of Ultra Grey RTV silicone on each side of the gasket, and no leaks.

Here is the gasket material that I use.....

I didn’t get an oil pump with the purchase of the Ute so I get why I don’t remember it when dismantling. Just looked for one and the price for a nason new one is more than I paid for the whole ute. So looking for used from wreckers etc. was $716 aud. I’ve got part number as Opma16. Is that correct. Always peaks and troughs doing a project like this and finding that out was definitely a trough. But all ur help and info just gold do thanks

Yes. On a G6 engine (B2600i Truck), the Oil Pump is sold with the whole front timing chain cover also......so not the cheapest. When rebuilding these G6 engines though, I always buy a new one.

I’m confused because isn’t that the back of the water pump that oring u sent photo of. Where does oil pump go. What is p/s oil pump is it power steering. So confused. Feel like a numb nut.

If you don't have a coolant leak where the steel coolant pipe is inserted into the rear of the cast aluminum part (that your lower radiator hose connects to) that I circled in my picture on post #3, then just save that O-ring......don't install it now.

Here is a image that shows the parts breakdown diagram from one of the online Mazda dealerships.....the O-ring is part number 15-287 in the diagram below.....
