    Thermostat Housing / Waterpump Repacement Costs

    Hi All,

    MK7 Golf GTI, 45,000 miles on the clock and no warranty. Coolant guage dancing from 90C up to 120C and back down again. ACC and Stop Start deactivated. Limp mode occasionally. Coolant level checked - doesn't seem to be losing coolant.

    Had it in to VW dealer (Berkshire UK), who says the waterpump and thermostat housing need replaced - 6.5 hours labour @ 1350. I haven't seen the breakdown of the part costs vs labour yet but I'm of the impression that they may be try to have my pants down.

    Change my mind?

    Yes it is highly likely to be the water pump but six hours is too much labour, I am getting much slower as I get older but I did one of these in four hours a few weeks ago. Unless it is obviously worn, don’t let them bully you into a new drive belt, it may only cost 15 but takes an hour to fit. The pump unit is 176.80 genuine (at the moment genuine is the best idea, decent aftermarket units are not around yet) so I am struggling to see where they get the total estimate from. With coolant, parts and labour this would be a 500 job at an independent specialist like us so 1350 needs some explanation.....

Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Thanks for the response Crasher. So they've broken the bill down to about 460 on parts (Thermostat housing, water pump, coolant, screws / bolts / seals etc) and then 880 on the labour. There's no mention of the drivebelt in the parts breakdown to be fair but perhaps they've added that into the labour costings.

    I've since rang another dealer in Hampshire and have it booked in for the same work at about 425 for the parts and just over 500 for the labour. It's a difference of just shy of 400 between the two dealers! Aware that it's still a lot of money over an independant but if these parts are prone to failure then at least there's a small chance of a comeback if they fail again. Maybe...

    Just to update. Had the work done at the second garage and all is now well. Comparison below between the two dealers prices show it's worth asking around.

    Marshalls VW - Reading

    Parts - Pre VAT
    W06L121111K Thermostat 216.79
    W06L121012A Water pump 69.76
    WN91096901 Screw x2 6.86
    W06L121131 Union 0.78
    WWHT00168 Seal ring 2.21
    WN91099101 Bolt x2 2.48
    WZGBQDW05L Quantum Mixing Water x4 13.40
    WG013A8JM1 Coolant x7 74.20
    Above parts plus labour = 1345.18 Total

    Martins VW - Basingstoke

    Parts - Pre VAT
    06K133073 Gasket 14.23
    06L121012A Water Pump 69.76
    06L121111L Thermostat 216.79
    06L1211131 Union 6.86
    G013A8JM1 Coolant x2 21.20
    N90765301 Seal x2 1.82
    WHT001163B Bolt 1.10
    ZGBQDW05L Quantum Mixing Water 3.35
    Above parts plus labour = 936.55 Total

    A hefty bill either way but nigh on 400 difference between the two dealers.
