I had coolant leaking from the front of the engine, only discovered when my radiator burst and the temperature gauge went to maximum. I ordered a new water pump, radiator, thermostat and gasket and new belts (as only the alternator belt had been changed since I bought my Mk1 150,000 km ago). I'd inspected all hoses and they appeared ok.Ordered early afternoon and that evening I sprayed as many nuts as I could access, with WD40 to help when coming to remove them. Next morning I checked the order tracking to find expected delivery was 1400-1500. On cue, the order arrived just as I was finishing parts removal and cleaning the old gasket off the water pump mount. Apart from half the screws retaining the plastic cover under the engine front breaking, everything came off OK.Fitting the pump was a little fiddly but not difficult. It took quite a while to clean off all traces of the old gaskets and it was easy to miss bits so take time. Holding the new gasket, and the smaller side-entry gasket, in place was almost impossible and I eventually resorted to tacking them in place with vaseline - a practice which I believe is frowned upon but I judged it less risky than kinking the gaskets. I also gave up on the top rubber dust seal as I could find no way of keeping it in place. There was not one fitted to the pump I took off and I was worried a poorly fitted version might catch in the timing belt. The new pump had a cast metal impeller, the one I took off was pressed stainless steel. The outer rotating plate onto which the pulley fits was a circular disk on the new pump, rather than the three-spoke hub on the old one and as shown on the picture for the new item. This made it impossible to secure one of the dust cover retaining bolts unless it was inserted part way into the cover before positioning the cover - easy to work out but worth a mention.The hardest part of reassembly was accessing the two bolts holding the side-entry feed to seal the gasket. It was not possible to get a torque wrench on them so I tightened as evenly as possible with an open ended spanner. This was slow as only a small turn could be made each time due to access. Incidentally, the removed pump spun freely and was probably perfectly ok to refit, there does not seem to be much to go wrong with them other than bearings. In most cases, I suspect, new gaskets are all that would be required but the work would be exactly the same.

Hi,I bought this item on July 2011, fitted on September 2011, I first had coolant leakage coming from the poor main gasket coming with this waterpump.I decided on January 2013 to replace both gaskets (main and secondary) with metal OEM gaskets.But... when fitting the waterpump again I realized one of the 2 screws (fixing the secondary gasket) was turning wrong: in fact the "bolt" of the waterpump had broken at only 15 Nm!!!!!Wow, what a poor item as Mazda indicates to fix these screws between 19 and 25 Nm...

A great Aftermarket waterpump. It fits well and the blades are made out of metal and not plastic as in other reviews. The engine now sounds a lot quieter, compared to my old worn bearings on my original waterpump. I also took the oportunity to replace my Timing belt while I had the timing belt off.Again next day delivery......Thank you!

Arrived quickly but the impeller was broken. I called to inform mx5parts but they would not send another until I returned this one, I find their lack of trust very annoying!! This was part of a large order costing £270, in addition to this part being broken there was also a missing part from the order (oil pump O Ring). This is the 3rd time I have had to return goods that were incorrect or broken, you really need to get a grip!!I am seriously considering not using mx5parts again as their customer service has reduced dramatically over the last few - I returned the water pump recorded next day delivery, it cost £9.05p and I want that money back!!Barry SpiersEditor Note: Sorry to hear you have experienced problems with this order and the service you recieved. Someone will be in touch with you very soon to get to discuss the situation and get the matter resolved.

part arrived quickly - great service. Garage fitted it for me and a new timing belt for 4 hours labour. They were surprised how perfectly it fitted as it was an aftermarket part. mx5parts came up trumps again!

Delivery Information - MX5 Parts

We understand that its really important for you to receive your goods in a timely fashion and for a competitive price. To ensure that we can deliver this we have developed a strategic partnership with both the Royal Mail and our courier partner, Think Worldwide.

At the present time, we only offer one delivery option ‘our carrier’. We will dispatch your goods with the most suitable carrier, for main land UK deliveries this is normally Royal Mail 1st class for packages weighing under 2kg and Think Worldwide for those that are over.

Our delivery charges are based on the weight of the consignment and the destination address. For UK mainland deliveries they start at £2.95 for a package weighing under 200g and rise to a MAXIMUM of £9.95 for a package weighing 2kg or over (EXCEPT very large bulky items that have an additional shipping surcharge added). The exact delivery cost will be clearly displayed at checkout.

Delivery times are estimated at 1-3 working days by Royal Mail, and 1-2 working days by Think Worldwide for mainland UK addresses. If you order before 3pm, Monday to Friday, we will dispatch the same day. If you order after 3pm, we will try to dispatch the same day, but if we cant it will be the next working day. Items ordered after 3pm Friday or over a weekend will be dispatched Monday. Items dispatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be dispatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items. If we have run out of stock and can’t dispatch your order the next working day, we’ll email or phone you with a revised dispatch date. You can then either accept the revised dispatch date or cancel the order, as you wish. Please note, shipping times are an estimate, and can not be guaranteed. Please note that during special offer periods, dispatch of your order may be delayed slightly due to high a volume of orders.

If you want it left, you need to give us your express instructions in the ‘additional information’ box at the end of the checkout process. It would be helpful if you could also indicate exactly where the package should be left.

Please remember, even with Royal Mail deliveries, that any items which are too large to fit through your letter box will need someone to be available to receive the delivery.

Our Guarantee - MX5 Parts

We guarantee “always fair prices”

MX5parts maintains an everyday savings pricing policy. We watch other retailers closely and maintain competitive pricing. The internet being the beast it is means that any Tom, Dick or Henrietta can set up a website in their back room and charge bargain basement/off the back of a lorry (guv) prices. Often they will have no stock, no returns policy, questionable security, no guarantees and of course poor customer service. MX5parts strives to be open and honest, so we will never inflate our prices to set up an artificial ‘sale’ (a common – and illegal – retail practice).

It is inevitable in an open market like the internet that there will be some individuals selling some items cheaper than we do, and some selling them for more than we do, just as in the high street. We take great pride in offering a fast, efficient, friendly and secure shopping experience, with great products at fair prices. We encourage our customers to shop around, but are very pleased to welcome them back again and again.

We guarantee to despatch your order when we say we will

If you order before 3pm, Monday to Friday and we have your items in stock , we’ll despatch the same day . If you order after 3pm, we’ll still try to despatch that day but, if we can’t, we’ll despatch the following day. Items ordered after 3pm Friday or over a weekend will be despatched Monday. Items despatched on Friday are for delivery the following week. Items ordered over a Bank Holiday will be despatched the next working day. MX5parts is constantly updated to keep pace with changes in our stock but demand is high and we occasionally run out of popular items.

We guarantee that we won’t pass your email details on to anyone else

Absolutely not. All your details are treated as strictly confidential. We’re internet users, too, and we know how annoying unsolicited email can be. We wouldn’t risk annoying you by being the cause of it.
