I have a 4x4 2000 Grand Vitara with 116k miles on the 2.5L v6. We bought it (cheap!) knowing the tensioner was failing. It still has decent power, and from the sound of it the chain hasn’t jumped. We bought it and parked it, and the parts are on their way. My intention is to replace all the timing components, the water pump, and the oil pump, as well as replace the tranny filter/strainer and fluid. I’ve read through the excellent write-up on the H25 timing chain here on the forum, along with Max's write up of his H25 engine swap, and looked through the service manual instructions on the procedure. It’s a lot of work, but I’m confident in getting it done. (Not my first rodeo with OHC engines.)
Given that I'll be replacing all the timing components as well as the oil pump and water pump, from the write-ups on this site it looks to me like it would be just as easy (possibly easier) to pull the engine rather than deal with all the space constraints if it stays in the engine bay. The added benefit, of course, is I'll be able to check the rear main seal while I'm at it and replace it if need be. (I'm honestly considering just replacing it while I'm in there.) I have an engine hoist and stand and ample tools/space for the job. Am I right that pulling the engine is the sensible route, or have I missed a caveat?
Thanks in advance for the opinions. I was thrilled to find an active forum for these great vehicles. The voice of experience is always a great thing to have available.
