Timing Belt / Water Pump...Help Required

I guys, just after a bit of advice please.

The car is a 2007 D3 2.7 TDV6

We had a Land Rover specialist replace the timing belt and give it a service last week. Picked it up on Friday.

On Monday, the engine went pop and Julie pulled in. The less said about her near 4 hour wait to be recovered by the AA the better, especially as she was a lone woman with a 10 year old child. That's for another day. back to the car. It was recovered back to the garage that did the work the previous week. When they opened the bonnet, one of the technicians actually pulled out a belt and looked at his colleague. They started whispering to each other, and Julie was ushered away politely.

This is what the garage have emailed me this morning after I asked for an update....



Hi Chris

sorry for the delayed reply i was in west scotland all day yesterday.

the water pump has sheared 2no mounting bolts off and caught the cooling fan snapping some blades off.

it appears to have been changed at some point for a cheap aftermarket part with the wrong grade bolts. i have got one coming today along with a new belt. ive got a used fan that i can put on as they are very expensive new.



So, my question is this. I know that timing belts and water pumps are linked in together in a lot of cars, and the water pump often needs changing at the same time as the timing belt. Could the garage have overlooked something, failed to tighten something up, overtightened something?? Would it be obvious that the water pump he is referring to was a cheap aftermarket part with incorrect grade bolts??

All help and advice gratefully received before I get back to the garage.

Cheers

Chris

Possibly they have undone one of the water pump bolts by mistake when taking the covers off and not tightened it correctly when refitting and then the other two bolts have failed due to added strain.

I would be demanding new parts fitted at their expense.

Thanks for the reply. So do the water pump bolts need to be disturbed/loosened whilst doing a timing belt change?

Is it not recommended to change the water pump at the same time as the timing belt on these, as is the case with a lot of cars?

Water pump shouldn't be touched when doing the belts.

IIRC yours is in the age range to have the oil pump changed as they are prone to failure but no actual requirement to change the water pump. However some do replace the water pump as it's easier as you already have everything else removed.

Also ask to see the pump and get any photos of part numbers etc on it, you'll soon know if it's genuine or not.

I dont know about the water pump but on a 2007 the oil pump must be changed to the later, stronger version (but up to you to tell the mechanic to do it).

If the oil pump was not changed then a failure of the water pump may well be a blessing in disguise as when the oil pump failed as it would have done before too long, you would have been up for a new engine.

I'm sure the oil pump was replaced not long after we got the car. I'll check that.

The water pump pulley has to be removed to take the cambelt cover off.


Maybe they didn't tighten the bolts back up after the belt went back on.


The fan pulley has to come off too.

Its a common fault that when the cambelt cover is removed , the water pump bolt just below it gets undo instead of the cover bolt, they are more or less in the same place. As they are only 6mm threaded bolts with an 8mm head, if one is missing it puts a lot of strain on the other two and you end up with your situation.
The number of posts on this board about this same subject when the belts have just been done is a lot...

I dont know about the truth the garage is giving you the reason for it, but if that was me I would say Censored its a lame excuse.
If the car is fixed ok and your happy then fair enough, but I would not be paying for any work done as it just to coincidental that its happened after the belt job.

Thanks everyone, great information.

I have just read this through....

The composed this friendly email to the garage....



Hi Mike,

Thanks for the update.

I have been looking into the possible reasons for this situation on the Discovery3 owners club forum, and it seems it happens quite frequently, usually a couple of days after a timing belt replacement.

What happens is the top bolt on the water pump is slackened by mistake as it is close to the timing belt cover bolts and water pump pulley bolts. It subsequently stays loose, putting extra strain on the other two mounting bolts. These are obviously the two bolts to which you refer in your earlier email.

The situation, like I say, has happened on numerous occasions to other D3 owners, and the dealer/garage, in almost all cases, admits that was the likely scenario and settles the repairs. I'd like to think we have found a garage we can trust, and will use again in the future, so I'd hope this matter could be settled in a customer friendly.

I look forward to your response.

Best Regards,

Chris




Response awaited.

Unless the cam belt was being done at the time there would have been no reason to replace the oil pump on its own.

With some exceptions the original oil pump where fitted at manufacturer is OK until the first cam belt change - this process in changing a cam belt tensioner that is attached to the oil pump causes the oil pump housing to crack and the cam belt loose tension.

So unless the cam belt has previously changed by the previous owner a long time back it would have been unlikely the oil pump was changed just by itself soon after you purchased it. So if you do not have the new oil pump, and it was not changed when you had the belts done you may well be living on borrowed time.
