Intake brace and devil hoses.
On my 97 when I bought it, it had a by-pass hose that had replaced the oil cooler hoses. I wanted to go back to using the oil cooler and I wanted to get the by-pass hose gone as it was also in the way of removing/replacing the oil filter. After removing the intake brace and oil filter, I still found it difficult to get the clamps loose on the hoses that been left on the oil cooler.
I ended using a 1-1/8th inch socket and removed the oil cooler. This way I could just pull the oil cooler out with the hoses still attached. This also gave me an opportunity to see what had failed on the hoses and as suspected it was up near the back where an oil leak from the CAS had ruined the hose. I had already bought new hoses and got them for about $15 for both thru the local Mazda shop.
This also gave me an opportunity to clean the oil cooler and it had some flaky residue where there had not been any coolant in for a while. I put the hoses on and wormed them back to where they connect and then put the nut back on the cooler then reconnected the hoses, front and back.
Now, my question is has anyone had any problems after they left off the intake brace. It does help a little not being there when going in from the top when changing the filter, and would help a lot if going in from the bottom if you have the bottom cover off, which I don't.
Anyway, after putting in new antifreeze and distilled water and new oil and filter I cranked it up and no leaks. I can sure understand why these are called devil hoses.
