also unrelated question (im a bad thread person) 5)where do i get the crusher washers for the oil coolers, i have one leak coming from one of the outlets of the OC. 6)should i attemp to take that line off (are they tightnened real tight?) or just swap the whole thing out? cos i have another one but not as many good fins. ive hear the week point for the OC's are the outlet for the lines.

Im almost on the road, thank god.

thanks heaps for your knowledge.

 

im talking about the drain hole on the engine block btw

 

Im pretty sure its on the middle iron. Where you fill the engine with oil. I think its a 14mm, not sure...forgot. Its at the very bottom. cant miss it

 

The washers can be obtained from autostores and/or the dealer. They are copper (been told you can use aluminum). There are 5 washers to the oil cooler, though the 5th, I haven't worked with.

1 washer on the top oil cooler hole size:5/8
1 washer on the bottom oil cooler hole size:5/8
1 washer on the front of the engine (short hose to oil cooler) size:3/4 or ~17mm
1 washer on the rear of the engine (long hose to oil cooler) size:5/8
1 washer on the oil cooler as a drain plug

I looked at Home Depot, OSH, Ace Hardware, Kragens, Autozone (had some washers), and finally found 3 out of 4 washers at Mazda which in turn had bought them from a non-franchise auto parts store in town. I got my fourth and final washer at said store.

Forgot to mention, the washers cost me ( I bought ~30 in my process) 20cents - $2 each. The dealer charged me like $2.16 for 8 of the 5/8th washers while the non-franchise autopart store (the dealer's source for washers) charged me $1.25 for the 1 17mm washer. Lol. Anywho, the ones you want are pretty cheap just so you know.
