Dephaser & water pump

[Tim.]

Are there set intervals (mileage/years) at which these two should be changed?

Would you only do these at the same time as doing the belts or do people ever do them in isolation?

Car is on 49k, cam & aux belts were done in May 2011. Should I be concerned that the dephaser & water pump haven't been done?

Car has regular & frequent oil changes but is there anything else engine-wise I should be wary of? Just want to make sure everything is in the best of order.

Comments & advice appreciated

No I have not changed mine when both belts were done, water pump not making any noise or dephaser not rattling .

No fixed intervals iirc. its just recommended that the dephaser is changed, Water pumps rarely go either (although mine did).

If the water pump was to fail it's run off the aux belt so not a timing belt off job...

personally if they haven't been changed before then get them done when you have the belts done nextime.

Dephasor will make noise for ages before it fails. Water pumps are generally reliable but normally give the game away by leaking before they fail totally.

Ie neither of then are likely to suddenly right your engine off like a belt going. So don't panic.

 

[Tim.]

Thanks chaps, that frees up a little more money for fun stuff

 

[Dan@SJM]

Certainly budget for a dephaser when you do the belts next.

The water pump has started leaking on my car. Apparently it just runs from the aux belt, so there's no need to change the timing belt at the same time?

Both belts were last changed at 47000 miles in 2009 so will be due again in 2014.

Would I be better just to have both the belts done again at the same time as the water pump? I don't think the dephaser sounds great either. I have actually thought this since before the belts were last done, however, when I pointed this out to the garage they didn't seem to know what the dephaser was and looked at me like I was some sort of mad man!

I don't want to spend money having the work done, then for something else belt related to go in the near future. Is there anything else I should be considering changing as well?

Thanks

SWR in stirling are very familiar with the belts and stuff on the f4r's i'd take it to them!

Cheers, will give them a call!

My only concern would be getting it there, should be fine if the coolant is topped up? Seems to be a relatively slow leak but definitely from the pump.

If I end up getting all belts, water pump, dephaser, service etc is that something that could be done in a day? Drop of morning and pick up later? (I'm sure falkland had the car for a couple of days just for belts and service)

As said the aux belt runs the water pump, but it all depends on how bad the pump is leaking as coolant can contaminate rubber - IMO i'd get it checked but do the aux belt and water pump now, and budget the belts and dephaser at a later date

 

[Adam G]

Lee, it's about half a day's work for all you need.

 

[Lee.]

Thanks. I think with the risk of the belt getting contaminated and being due again next year anyway, I'll just go ahead and get all belt kits, water pump, dephaser and service done at the same time.

£770 all in reasonable/average?

Better still, Kenny Brown Motorsport in Hillington Estate? He's done loads of F4R's. Great reputation aswell!

It should only be a day for the wory mate yes, unless there are any unforseen problems which with cars as you know you need to allow for!

I'd try to get it s little cheaper mate, full belt kits plus dephaser are circa £550-£600 at the specialists on here, can't see the water pump costing that much extra?

Unfortunately not as great a selection of specialists in Scotland!

Had a quick look at the cost of the parts online, £500ish:

Cambelt kit £142
Aux belt kit £72
Water pump £67
Dephaser pulley £153
Service kit £30
Oil £30-50

Charging about £270ish labour then. Suppose not too bad depending on how many hours it will take them. People saying about half a days work, 5 hours?

 

[The Chubby Pirate]

Even £770 seems a little on the expensive side doesn't it?

Have you been on swr's website to see their prices??
​

 

[lemonnobby]

5.7 hours for a belt i would add 1.0 on that for coolant and water pump then the service example 90-100 for a service

 

[Mark-F]

sorry to hijack, regarding the dephaser rattle, how long before it fails on average, and when it does fail, does it take the cam belt with it?

Yeah mate, had a look after I called them.

​£380 for the timing belt and £220 for 36k service. So I suppose an extra £170 for the dephaser and water pump (150+70) isn't bad, but not exactly a bargain!

Don't think anybody knows as they get changed before anything happens. Mine was noisy for nearly a year.

It would have to be left for a long time with a monstrous amount of noise before it got as far as actually failing. I dont personally know of one where someone has done so.

I'm not that far from you, and currently have an offer on cambelts and dephasers. If yours is a NON AC variant, your looking at £430.
