hey all just discovered a water leak under the throttle body coming off the block into a small plastic piece then out into a rubber hose that goes to the heater core the plastic piece has a pinhole in it not the hose was wondering if someone could tell me what that piece is called so i can replace it any help would be great also how to get it off looks like i need a special tool or something thankx

 

Any chance you could take a picture? It's a bit hard to tell what you're talking about from your description.

 

Sure will give me a few mins

Is this is on the driver's side of the block, beneath the oil filter pedestal and going into the rear iron? If so, you can just remove the plastic piece and use a couple of good quality worm-gear clamps on the hose.
EDIT: It's what I thought. Yes, you can remove it. Either use a couple of small screw drivers to insert into the sides to pinch the tabs. As you do, pull to release. Or just grab a set of channel locks and twist to break it off.

 

Stupid question now, how do i get it off do i need a special tool?

 

See my earlier post under the edit.

 

Thanks Man, Just wasn't sure n didn't want to mess anything up. I didn't know if that part was necessary or not....

 

Yeah it isn't necessary, my car doesn't even have one.

 

It is a quick disconnect. You can buy replacements but I just broke mine off and double clamped the hose directly. There are posts though that give an alternative part, I think it is a Ford piece that you can buy at any parts store. The plastic piece is prone to crack though and I have had zero problems since removing it.

 

Might as well also check the tiny little 90* hose under the throttle body. Those split open over time as well.

Ray at Malloy Mazda can get you the parts at a discounted price. His number is in the FAQ thread.

Since you're going to have to drain the cooling system, you might as well check and replace other coolant hoses as well. Check the 2 tiny ones that go to the turbos. Use new OEM clamps as well. They have the correct torque to properly clamp the hose w/o chewing up the rubber like the worm type hose clamps do. My experience with this car's coolant system is that when one issue starts with a hose or other components, it can be a warning sign that other parts are worn and need attention/replacement. Might as well find out in you driveway vs hundreds of miles from home in the middle of the night.

Good luck.
