Windscreen Cowl Grommet, MX5 Mk3/3.5/3.75

SKU: SI6472

Genuine Mazda Part

Genuine Mazda replacement windscreen cowl screw grommet. Believe it or not, this little blighter can be the cause of water getting into either the drivers or passenger side footwell. The foam gasket on the back drys out and falls apart leaving a direct path for water to follow into the cabin of the vehicle. There are two required per car, and they are located at either end of the windscreen cowl. Simply pop out the black oval shaped cap, removed the screw underneath, lift up the cowl itself to give you access to the grommet underneath.

Fits all Mk3, Mk3.5 & 3.75 models, 2005>2015

Tip: It might also be worth ordering a couple of the Hole Covers at the same time as these also go brittle and often break when trying to remove them!

Such a simple and cheap fix. Just replaced this on mine. Old grommet rubber was old and useless, water dribbling through dashboard into the footwell. Just remove the trim in front of the windscreen to replace. 15min tops 🙂

Ordered 2 from Ireland and arrived in 4 days. Great service as usual despite all the turmoil. Simple to fit and resolved the issue immediately. I used a little silicone to be absolutely sure You guys deserve a lot of credit and when all our woes are over you can count on our support.Keep heads high.

Like in the other reviewers I too had complaints from my wife of water dripping into her, and into the passenger foot well dampening the carpet.Elsewhere I also had read the horror stories of looking for blocked drain tubes etc.But this is the solution.This little beauty has saved the day, as mentioned the gasket is a very thin foam, it had dried up and had began to disintegrate, it's a poor design, no barrier for water.Very easy to get at for replacing, the other guys have set out the way to do it, I didn't need to remove wiper blade, and I was very careful removing the screw hole covers, so didn't need new ones, and yes, do use silicon to create a good seal. One happy customer and no drips.

Have just fitted new grommets to the cowling after my wife complained of being dripped on.Although there was no evidence of water inside the car, it seemed prudent to put a stop toit before further deterioration of the very thin foam gasket. With the cowl out of the way,access is then available to give the area beneath it good clean out. Use a silicon sealantto "glue" the grommet in place and only tighten the screw just enough to hold the cowl inplace. Use new hole covers as the old ones will probably be brittle and anyway, breakingthe old ones out is better than damaging the cowl trying to get them out whole. A new cowlis expensive! Job done and neither my wife or I will have to put up with the damp patch.

Parts arrived really quickly and were just what I was after. I had a problem of water leaking into the passenger foot well and the cause is a leaking grommet. I had a windscreen change a while back and a reckon it disturbs this vulnerable seal. You can see how it deteriorates over time. A poor design really.Replacement is really easy. I just removed the wipers and the cowl. I used some silicon sealant (bathroom sealant) to "stick" the grommet in place as a bit of extra water tightness. Cheap fix !!!!

Had a problem with water leaking into the footwell on the passenger side, went on some forums that described all sorts of horrors and blocked drain holes but then saw mention of a leaking grommet after a windscreen replacement. As it was a cheap fix I thought I would try it, wasn't confident about it. Part came very quickly and I gave it a go. Didn't even have to get my book out, it was straightforward. Took off wipers and scuttle plate and removed the old ones. I replaced everything,only took about 20 minutes. Still wasn't convinced but since then it has poured down and not a drop! Sometimes the simple fixes do the job! I think I could have done the job without taking off the wipers but it was hard. If you have to get the screen replaced get a couple of these as well, save you some hassle.

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 1.5kg 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 £1.97 for a package weighing under 300g and rise to a MAXIMUM of £9.95 for a package weighing 1.5kg 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.

Please send it somewhere it can be reliably signed for, like your place of work, a neighbour, or perhaps your grans. We can (but we don’t like to) ask the courier to leave your parcel without a signature. If we do this, it will be YOUR responsibility if the parcel is lost or damaged. 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.

If you need to change your delivery address, for any packages that have been dispatched with Think Worldwide, there will be an additional charge of £9.95 if the package has already been dispatched.

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 to replace any goods which aren’t suitable

We guarantee to accept back any goods that you do not want, are not suitable, have changed your mind about, infact, for ANY reason, provided the goods reach us within 30 days of dispatch from us, in their original condition and packaging. Please tell us why you are returning the items, just for our records. The original purchase price of the goods will be refunded on to the card that was used for their purchase.

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.
