Ive got an NA6 but had the same thing happen to me, the hose swelled and split.. decided then to replace both the in and out heater hoses at that point..
I had to take the bracket that holds the rear of the spark leads off.. from memory its only attached via one bolt...(on the back of the engine)

Unbolting that bracket and moving it to the side should give you more than ample room to get your hand in there..and allow you to twist/spin the hose off the pipe, Well it did on the NA6 anyway.
(sometimes poking a small screwdriver under the lip of the hose works to break the corrosion free of the rubber, before attempting to pull it off, id prob only do that with hoses your planning to throw away though)

The clamps will open up with a set of pliers.

Be careful with the pipes that go into the heater. They are very thin and easily deformed. Once you get the clamps out of the way it's best to carefully cut the old hose off with a knife.

Lucky_Luke,

The coil pack is held on with 3 bolts. Two up the top that you can see and one down the back of the engine.

I would also check ALL the other water hoses If one goes the other won't be far behind them :cry: and you could end up in the same situation again :evil:

Definitely do all hoses.

I had the exact same coolant pipe blow on me - I should have replaced it but didn't. I lost all of my coolant but rolled (with the engine off) into a BP servo.

After finding that it was that hose, I pulled the hose off and found the hole. So I just simply chopped that part of the hose out and it still managed to fit. Then I refilled with water and went along my merry way - no tow required. :)

Leaking CAS 'O' ring drips onto the hose and breaks down the rubber. Mine was very soft when I had the motor out a few weeks ago so I replaced it.

:idea: Instead of using the Mazda clamp I used a screw type one in the correct orientation that is easy to get at the next time because it is pretty tight behind there.

Definately replace ALL the hoses and clamps while your at it.

And buy a tube of PBR Rubber Grease smear a little inside the hose before installing it.
Makes it slide on easily and more importantly stops it sticking to the pipe allowing easy removal next time.

Best advice I was ever given :D
