It's a little more accessible, but you can't see it so much here, but there was leakage at both tank scenes.Īnd you know, this is the original rad, so really good life out of this radiator. And we replaced that as well, which is a little bit of extra work on top of the timing belt, but not a lot since we had covers and things, parts removed already. The only other thing we ran into is the radiator was starting to leak. The tensioners as well, there are tensioners that have bearings that rub against the timing belt, idler pulleys, tensioners, those all get changed at the same time. Timing belt, oil seals to a certain degree. Was there any other issues?īernie: Yeah, so I was going to say you know, like the water pump, to us it's a standard job. And that's definitely a something we don't want to do. And it's driven by the timing belt, so if it seizes up, the bearing fails, it seizes up, then it'll damage the timing belt. Not at any large rate, but some coolant has leaked and with this kind of mileage, I mean, not doing the water pump is kind of a crazy thing, because it will fail for sure over the next while.Īnd then you have to take everything back apart again. It goes through a passageway and can run out, but you can see this festering of pink here, there's cooling that's been leaking. This prevents coolant from actually running onto the timing belt. Anyways, the water pump was one item we replaced. They'd be leaking oil all over the place. Whereas in the olden days of seals, sometimes we'd take them out and they'd be hard as hockey pucks. Sometimes lasting I don't want to say the life of the car, whatever that is, but they may last for decades without failing. Your oil seals were usually leaking oil, but again manufacturers make them out of much better materials. By the time your timing belt was worn out. We also changed the tensioners and most of the time we change the front engine oil seals as well because they tend to leak and cause problems. Mark: What else did you replace with the timing belt?īernie: Well, the water pump for one. So things are not fully back together, but at least it gives a view of the engine compartment. You can see it's kind of sitting on an angle. As I said, these are with all the covers installed, but power steering pump is kind of loose here. This is the variable valve timing actuator.Īnd there's the belt. I don't normally say too many bad things about Toyota's they eventually they'll well, it's a Lexus, but still a Toyota. They made them more reliable, with less frequent replacement.īernie: It's a V8. So you can see the belt in here, but it's quite a wide belt, well over an inch wide.Īnd as I was saying, like in the olden days, they were much thinner and they never lasted as long, but manufacturers got smart. I didn't take pictures all the way through the process, but this is one of the cam shaft covers back on. This is actually the new timing belt installed. So there's a view of the front of the engine. You can actually look at a couple of pictures right now and it kind of gives you an idea of what the belt looks like. And they evolved into curved tooth belts with that they're much wider. They used to be these skinny little belts that had square teeth. I think it's always should be replaced, but they're just much more reliable timing belts in the, I mean, I'm working on cars for a long time. And so they will generally last quite a lot longer than the service interval, but I wouldn't recommend you do it because if it breaks, I'm not giving any advice here to leave it longer. For some reason my kilometre calculator isn't working right now, but I think that's somewhere in a 150,000 kilometres, somewhere around there, 150, 160. Mark: What's the replacement interval for timing belts on this particular vehicle?īernie: Yeah, so on this vehicle, it's about 90,000 miles. But yeah, it was time to do the belt from point of view of preventing anything from breaking. So it was not actually due by mileage yet, but you know, certainly by time this vehicle is now 16 years old, in great shape by the way, it's very low mileage for a vehicle like this. Mark: Was there any kind of indication that there was something wrong with the belt?īernie: No, nothing wrong with it actually, just wanted to do it based on the time of the vehicle, the odometer at about 91,000 kilometres on it. So this vehicle was basically due for timing belt replacement. What was going on with this?īernie: Yeah. There was a timing belt replacement for this huge SUV. Mark: So today's victim 2005 Lexus GX470. 24 time winners of best auto repair in Vancouver as voted by their customers. Vancouver's best auto service experience in Vancouver, BC, Canada.
