Timing Belt Replacement

I have a 2000 Tundra that has about 187,000 miles on it. I need to replace my timing belt and I also want to replace my water pump. Is there anything else I should replace in that area at the same time to save money and time down the road? ALSO, the Toyota Dealership I trust is going to do all of the work. I have done many things myself as far as maintenance on my truck but I dont want to screw this up.

 

If you're replacing the water pump then you might look into replacing the other coolant components as well. I don't know how Toyota's are when it comes to replacing cooling components, but in other makes when you replace one component it can cause other components to start leaking. So it's more advantageous to replace the entire system rather than just one component at a time and chase leaks down. Also check your belt tensioner and pulleys while you have the belt off.

 

Have them replace the thermostat while they’re in there. Since you have a 2000, have them check the condition of the lower ball joints. Another member just had a failure on an 01. They are easy to replace if you’re up to the task. Just replace them with oem if you do.

 

I always replace my timing belt tensioner and the two timing belt idler pulleys. It will add a couple hundred but if one of those seizes up bye bye timing belt and interference engine. Is it a 4.7?

 

I would have the radiatior changed as well.

I consider them disposable items.

A coolant flush is $90, a radiator is $125 or less.

 

All good advice from the above posters.

 

The Aisin kit that Toyota will use most likely comes with a new tensioner and pullies but just make sure it does.

 

Thanks! I will look into other cooling components. I have tensioner pulley on my list as well.

 

I will add thermostat to my list. Do you have a good video recommendation on how to replace to ball joints? I think I can tackle those myself.

 

I will look into that at Toyota. Yes its a 4.7.

 

Another minor item that is a good pre-emptive repair is to replace the alternator brushes at the same time. Since the alternator needs to be removed, it is eezee-peezee. A small brush module is available from Toyota and it bolts right on.

I actually changed the radiator myself a few months ago and had a coolant flush done about 2 months ago. I did notice an improved difference in how it ran after that, or maybe it was just me.

 

Good to know! I will ask.

 

Could you explain more on how that works? Im confused about "A small brush module is available from Toyota and it bolts right on.".

 

It doesn't look hard! Good video as well. Thanks!

 

Thanks everyone! Great ideas.

 

Not hard at all. Just make sure you have red loctite, 3-4lb hammer and a torque wrench and you’ll be good to go.

 

On the back of the alternator (under a sheet metal cover IIRC) is a plastic molded housing (about the size of a golf ball or so). This housing holds the brushes. You can buy a new housing with new brushes installed from the Toyota dealer. Make sure you have your VIN since there were standard and heavy duty alternators. Remove the screws holding the brush module in place and mount the new module. Electrical connections are made at the same time. There are two pins that hold the brushes in the retracted position, pull those pins and the brushes will snap against the armature. Replace sheet metal cover and you are good to go.

Most of the time when alternators fail it is just the brushes that are worn out. I have not replaced a full alternator on any of my vehicles for the past several decades, only brushes.

Here's a youtube video that shows the basic process. On my alternator, the retraction pin(s) were already in place.

I understand now. Thanks for the video! Good knowledge to know
