anyone have their timing belt replaced on their 3.4l?

I do inspect my truck on a regular basics. Your engine will give you some indication that something is going bad i.e leaky water pump or a slight misfire. I won't be that guy

 

Isn't the 3.4L an "interference" engine, meaning that if you let the timing belt break, you risk valve damage, etc? Someone correct me if I'm wrong.

either way, I just had mine changed at 80K, and I did the water pump and thermostat at the same time. That, plus oil change, changing diff oil to synthetic front and rear, changing transfer case oil, and a couple other small things I was to lazy to do myself totaled just about $700.

 

I paid $245 for the timing belt kit, and I bought the tool to compress the tensioner for $53. I'm planning on another $50 for new coolant and distilled water.

I'll do it myself for a total of $350.

I just went over 100,000 miles, and I'm doing for peace of mind. (In the spring when it's warmer outside.)

 

why you gonna wait when that timing belt goes your gonna be buying alot more than a timing belt. you probably end up dropping half you valves down into the engine. in other words your gonna end up buying a new motor!

i love having the four cylinder cause it doesnt have timing belt. it has a timing chain

 

The 3.4 is a non interfering engine, belt breaks call a tow truck, I have extra transportation so the vehicle being down is no big deal.

 

timing chains stretch fyi

 

im well aware but it takes a shitload longer for that to happen to a timing chain compared to a timing belt going out.

 

You may get a warning from the water pump, but a cloth reinforced belt won't be so kind. You are right, you just might get a warning in the form of a miss, but do you really want to chance it? They can go without warning and have done so. It is called preventative maintenance.

 

Preventive maintenance!! There's never a right time to break down. I use to ride motocross bikes back in the day and was always amazed how a cple of my friends would never go through their bikes before we set out on a road trip. They would just put gas mix in them and ride. Not even lube the chain! It also never failed that we had to stop and do repairs on the trail in the middle of our ride. Silly stuff too like tightening handlebars or re-gluing a grip. I don't have time personally to do things twice so I'm all for changing things if their due and you already done half the work. JMO!
