Seems that about 90% of coolant leaks come from hoses or broken hose clamps (at least thats what I think)If anybody knows ALL the coolant hose locations for the FD, id REALLY appreciate it!! im tired of coolant leaks, I wanna replace as many hoses as I can now that I have everything taken apart, hope anybody knows, id really appreciate any help!!

 

Call up Ray at Malloy Mazda at 888 533 3400, he sells the whole kit at a discount.

IIRC,
Upper and Lower rad hose----2
AST hoses-----3
turbo hoses (feed/return)-----2
rear iron to tb----1
tb to hard line-----1
hard line to rear wp hsg----1
driver's side heater hose to block-----1
passenger side heater hoses (rear of engine bay)-----3
Pass side heater hose to wp hsg-----1

That comes to 15 but for some reason I think there are 16......

 

Ok I already have 2 brand new radiator hoses ready to install, the 3 AST coolant hoses all feel and look brand new so I'll leave them alone for now, the turbo hoses are currently being replaced with 2 brand new ones, all of the throttle body hoses are brand new ( I checked them when I removed the throttle body to replace spark plugs) There is another coolant hose thats located where the spark plugs are, but cannot be seen because the manifold must be removed first ( this hose is also brand new). I think I almost got everything except for the heater hoses. I will inspect the heater hoses to see the condition, thanks
