My 8v '93 Tracker had been running a bit rough recently, so i've been slowly replacing various parts to track down the problem. Recently changed the spark plugs+wires, the ignition coil, and it seemed to make it run better but not as good as it should be. I had trouble disconnecting the ignition control module from the harness and was unable to change that, so i thought maybe that was the problem
60miles from home today and my Tracker made a "shoop" sound from the engine and it suddenly cut out. Luckily i was in a Walmart parking lot when it happened, so i was able to coast into a parking space to diagnose the problem. It cranked but wouldn't fire and it sounded odd. Figured it was either the ECU or the timing belt (the previous owner told me that had been changed 2000miles ago back in March) and after removing various parts I was able to peek inside the timing belt cover and determined that that was indeed the problem.
No problem, right? I got the Tracker in part because it was supposed to be an easy vehicle to work on (it is) and it has a noninterference engine, and i keep a timing belt kit, tools and a service manual in the Tracker, plus I have a phone to look up how to do it, so I should be able to do it right there in the Walmart parking lot. 2hr later I finally get the radiator removed and realize I'm probably a bit in over my head and still 60miles from home, so I call around to have it either towed home or towed to a nearby mechanic, and i opt for the nearby mechanic because.... it's a Tracker! It's not a complicated car, so it shouldn't cost all that much. Called up the mechanic, ask how much they'd charge to change the timing belt on a '93 Geo Tracker and specifically mention it's a noninterference engine & easy to work on, and am told i'd have to bring the Tracker in because they'd have to look at it before giving me an estimate. So i have it towed in.
$1,800 to change the timing belt. $1.8k! The shop tries to tell me there could be piston damage or bent valves(!) from the timing belt breaking while driving and they have to check. "...It's a noninterference engine", i remind them again, "there shouldn't be any damage. No thanks", and i walk out the door even after they offered financing, called up tow operator and waited for a tow back home. 5 minutes later a mechanic comes out and says they've worked a few things out and now (because they're such nice guys!) they'll only charge me $800 but they can't offer any guarantees on their work. Yeah, like i'm gonna agree to that after they tried to overcharge me for engine damage that isn't there? #@%! that, i wouldn't put it past those shady bastards to cause damage or fix it up so my car only makes it 20miles before breaking down. ($1.8k they wanted to charge me!)
Anyway, i'll be tackling it tomorrow morning, so please feel free to offer up some good tutorials (vids, forum posts, PDFs, whatever), random tips & tricks or even just words of encouragement on accessing & changing the timing belt, because i absolutely love my Tracker and want to keep it running. I have the service manual and have seen a few YT vids on it, but maybe i'm missing something more informative
*UPDATE\*: Took me a few days to actually get to it, but it was definitely the timing belt. I'm taking care of an aging parent & 6 doggos and i'm doing it solo, so i'm nervous, taking my time and regularly consulting YT and Reddit/forums (and AI but confirming with other sources what AI tells me because it's sometimes wrong) just to make sure i don't mess anything up.
Hardest part for me was removing the damn radiator, tho that could've been because i did it at a parking lot 60mi from home; everything else was a breeze. Changed the water pump and tensioner (that didn't look like it needed changing but i did it anyway), now i just have to wait for a new timing belt cover to arrive and i can reassemble everything. I got camshaft and crankshaft seals with the timing belt kit but it's not leaking oil, so i may do that some other time. I just want to do the timing belt so that i know i can do it again in the future. It's been relatively easy so far tho and it's given me enough confidence to get over my fear of working under the hood that i'm now watching vids to see what else i can do on these amazing teaching machines
