1/17/2024 0 Comments Subaru timing belt tensioner![]() My question is- do the OEM tensioners ever need to be bled prior to installing? I've never heard of this being necessary until dealing with this ridiculous NTN tensioner. From what I understand, it's the same tensioner that comes with the Gates "N" kit, which comes with bleeding instructions. Needless to say, I don't trust this tensioner at all & fully plan on replacing it with a Subaru OEM tensioner. Upon doing further research, I've learned that this is a relatively "new" NTN tensioner design, as Subaru holds a patent on their specific tensioner. ![]() This pesky oil leak may have just saved my engine!! Post belt change, its sitting at around 28 deg at idle. It was just sitting there, not expanded at all. Prior to tensioner replacement, OBD was showing my timing advance being (IIRC) 16 deg at idle. Grabbed a pin out of my tool box & inserted it through all three holes with zero effort. When looking over the belt to make sure it hadn't encountered any oil directly, I noticed it was VERY loose! Looked at the tensioner & it was fully compressed without the pin. Yesterday, I pulled the timing covers off to investigate a slow, persistent oil leak. The kit came with no special instructions, so I proceeded with the install as I have on several Subaru's in the past & once everything was lined up & ready to go, pulled the pin on the tensioner. I verified the belt was OEM & all pulley were made in Japan before installing. ![]() I had my local trusted shop install the entire kit with no issue. A couple months ago, I installed the RCM Timing belt kit. Purchased the Gates timing kit from Amazon, came with everything for a full timing service including water pump, tensioner, pulleys, etc.
