Subaru EJ2x Timing Belt Service

Subaru EJ25 DOHC WRX STI Built For 500+HP With Timing Covers Removed

Your Subaru Timing Belt Service is definitely not maintenance that you want to sleep on. We have all read and seen the horror stories on what happens if its not properly addressed. If your new to Subaru, congratulations on your purchase and here’s some information to chew on until your time comes (every pun intended)!

Your timing belt is just that, it is simply a belt that is used to keep your engines internal components mechanically synchronized. Your timing belt is guided by an assortment of sprockets, pulleys and a hydraulic belt tensioner as seen below. Over time these components begin to wear (some faster than others) and need replacing. Subaru places this service strategically in the 105k mile service interval in your Subaru Owners Manual. So bear in mind this shouldn’t be news to you but if it is then now you’re part of the informed.

Gone are the days of a simple all inclusive Gates Timing Belt Component Kit with Water Pump. This has been the standard for many years in our industry but as of lately non-original equipment manufactured components have made their way into the kits. We see more and more Belt Tensioner, Idler Pulley and Water Pump Pulley failures then I could live with while trying to sleep at night offering that to our customers (your friends and family). We now only offer OES (Original Equipment Supplier aka Subaru) Genuine Replacement Parts with an OEM (Original Equipment Manufacturer) Timing Belt.

“What does a timing belt service consist of” your probably asking by now right!? When your Timing Belt Service is done at CKR it is standard to replace the entirety of your Timing Components (Belt, Tensioner & Idler Pulleys). When your Timing Belt is replaced, it is mandatory to replace your Water Pump and Thermostat. These items are common wear items and its best to address them now or you will be paying for this job twice after a Water Pump failure. When performing this service, we also replace your timing cover seals, timing cover bolts and your front oil cooler crossover pipe as the are highly susceptible to the elements of New England. We also strongly urge our customers to take this service one step further and replace their Camshaft Seals (Camshaft Sprockets need to be removed) to prevent possibly oil leaks into the timing cover. Your radiator is drained during the Timing Belt Service and is replaced with quality long life engine coolant.

Other possible items that we may recommend need replacing during this service are your upper and lower radiator hoses. The upper coolant hose on turbo model Subaru’s especially are prone to ballooning with age and making contact with the power steering pump pulley or the radiator fan assembly. The accessory belts for both power steering and air conditioning will also be inspected and recommended for replacing if deemed necessary.

This service is completed with the engine in-vehicle and is performed same day as drop-off. The service typically averages out to 3-4 hours depending on your vehicles configuration (SOHC, DOHC). Our Timing Belt Service starts at $799 for most Subaru platforms and is all inclusive to keep your Subaru running to its 200k mile potential.

If your Subaru suffers from an engine failure, you may also need to replace your timing components and water pump when replacing with a used engine from a supplier like LKQ for warranty purposes. Labor times are adjusted for situations like this and generally include additional services like valve cover gaskets etc..

My goal with this article was to shed some light on common Subaru maintenance and some industry trends that are starting to become more prevalent.
