Any other parts worth changing with timing belt?

[Ben93]

I have my 06 corolla d4d 2 litre and its on 77k and has no proof of it being done in the service book and receipts but had had normal servicing regularly. I'm booking it in to do the timing belt and water pump etc and am wondering if there's any other belts or components that are worth doing on an 11 year old car on 77k. Just anything that makes sense while it's all stripped. 

 

Also is 480 pound a reasonable price for timing belt full kit water pump or is that o.t.t

Hi,

Not a diesel man, but for any car the books often say the tensioners and any idler pulleys are worth replacing when doing such work.

However when I did my  petrol Avensis asked the local dealer for a price, as assumed they would be regular replacement parts, but he said he had never ordered any even for their own mechanics when they replaced the belts, ie they were strong parts.

Yes, worth replacing them as had to also replace them and the cam cover at 91,000, after fitting a new belt at around 60,000.

[Ben93]

Oh OK will ask the mechanic about it not sure what tensioner and idlee pulleys are on the d4d to be honest. And when they need replacing maybe worth looking through the owners manual thing that I have. 

[Ben93]

The mechanic told me to replace the cambelt and tensioners etc like a full kit and the water pump? 480 pound for parts and labour. So it's not just the belt but the other bits that go with it? 

[olddriver]

I've seen mention about replacing the water pump elsewhere, but I've never changed mine in 140,000 miles.

[Ben93]

May as well while it'd all out. So if I do timing belt water pump and the tensioners etc for the timing belt that should be OK? I've seen water pumps fail on cars after new timing belts and then it's the Labour cost again a new belt etc etc. Not worth the hassle. 

[oldcodger]

False economy not to replace with water pump at the same time as the timing belt; bit like the clutch, always replace as a 3 part set.

Also what is diff oil says something about manual gearbox and front differential oil inspection but I'm assuming it's a visual check over for leaks and not to actually change the oil. In sure id know if my gearbox oil needed doing or was leaking anyhow I've never changed gearbox oil in any car. 

[Ben93]

Does the gearbox share its oil with the front diff? And does it actually need changing? Hearing mixed opinions on it. I've never done it on a car and they've all been fine. 

Just read alot into it says if you have a car that's old or not been done for a long long time you can do more damage than good changing it as fresh oil can loosen everything and cause havoc etc. Not sure how true this Is but maybe I'll just leaving its not like soft goin g into gears but not hard in any way compared to other cars. Still not sure about the diff oil though if it shares the gear oil or its its own thing.

If you use a toyota garage, more often that not they will replace timing belt and advise water pump. In an ideal world you would replace tensioner and idlers aswell and for other manufacturers that is common place. I would stick with belt and pump only and ask for idler and tensioner pulleys to be inspected, which should be done anyway. Once its done, monitor coolant level as it can drop below the max line after a coolant change once all air is completely removed from system.

Gearbox is complete with diff. The check would normally be a visual check of the casing and seals and to check the fill level to make sure level is at or near the fill line. Gearbox oil should be changed (even on cars with lifetime fluid) although the service sheet doesn't say when. I would replace the oil everytime its due its check personally

[oldcodger]

2002-2007 Petrol and 2l diesel manual gearboxes  transmission oil renew at 40,000 miles or 4 year whichever comes first ( haynes manual)  use  75w -90 gear oil gl4 or  gl5 (T handbook).

If it was mine, I would change it,  when getting a car new to you, you want to do a full service unless you have recent dealer stamps and detailed receipts, who knows exactly whats been done and what fluids have been used ?

What about the other service items, eg fuel filter, brake fuild, air filter,  pollen filter etc etc  ....?

 

[Ben93]

I've heard about gearboxes going wrong after oil change if it's not been done. I have stamps in the book but no receipts to say what was changed as such? The garage just says specialists in toyotas etc. Is it worth doing geaebox oil or am I asking for leaks and damage if I change it? 

I've already had oil and oil filter air filter changed as well as new discs pads and brake fluid so far. 

I'm a bit worried about the gearbox oil if it wasn't done prior it could probably knock crud off if disturbed and eat away at the gearbox seals and start going wrong. Not sure if it's an old wives tale though.

Hmmm,  name one ?      web chatter can often mislead and not present the full facts of a situation.

If you want to leave the old oil in , your choice, but its only going to be getting older and dirtier, and thats not going to improve the gears etc.

When you drain off the old oil, the sump plug is magnetic , so check it to see if there is much swarf on it, indicating wearing teeth etc, probably none.

The filler/level  plug can  be very tight to undo, so have a good fitting spanner and wear some thick gloves as space is a bit tight.

Don't forget the diesel has a changeable fuel filter, also the pollen filter can reduce heating if bunged up and the batteries for the keys will probably need changing.

All above well detailed in the Haynes manual, a worthwhile buy.

I changed the timing belt on my Corolla at 100,000 miles as it hadn't been done in 10 years. The belt looked alright to be honest. The water pump also looked new, but I replaced it anyway. 

Other than that, if you're having a diesel serviced then you should look to get the fuel filter changed as well. These can gunk up and any sludge or rubbish missed from the filter can end up in the injectors and block them.

[Ben93]

Awaiting price for the whole lot probably be well expensive cambelt tensioners waterpump fuel filter air filter gear oil and new coolant. Bet that's got to be around the 800 pound mark at least if so will do the gearbox oil myself and the air filter pollen filters etc 

[olddriver]

£800!!! provisional price for fitting the belt, tensioner and any idler pulley is £200 from a non Toyota garage, being carried out tomorrow.

[Ben93]

Managed to get the cambelt waterpump pulleys tensioner etc air filter fuel filter for 500 which is cheap for where I live.

Nice one! if you do the gearbox oil yourself, suggest you loosen/take out filler plug first before drain plug!

This! Otherwise you'll be in a world of hurt trying to loosen the filler plug once it's emptied itself.

Job done for £199.39 including VAT, this included 1.8 hrs work and the kit with the belt, tensioner and idler pulley for £49.16 + VAT.

You could have a couple of days in the south west, get the job done and still have some change for your £500.
