I have a coolent leak thats coming from the hose that gose from the motor to the TB and ive been trying to order it and every where i look it calls for a 3/8 size hose and it sounds to big can some one tell me what size i need the hose to be.

 

You need OEM. it's available from Mazdatrix.

 

order it from ray crowne...and get the fd one which is longer but has the same molded bend...believe me its a bitch to get on and off so longer is a win..the fd oem one from ray was 15 bucks shipped to my door cant beat it..malloy mazda here in nova everyone orders from him..17034908170
