Granville 1440A 10K 375ml Boost Stop-Leak Power Steering Fluid

Don't listen to the negative reviews, if used correctly this stuffs brilliant.So firstly,if you have a massive leak or a split hose this stuff won't work, it's not a miracle in a can ! Its not a substitute for replacing knackered and completely worn out parts.However, if you have a drip drip type leak then this could do the job but....I suspect a lot of ppl have been tipping the entire can in to their systems then becoming dumbfounded that the leaks got worse! This stuff is water thing and contains a solvent that revitalises seals , a little drop will do you! Start with just under a quarter of the can make sure the fluid is on the stick.Start car and rotate steering a dozen times, then take for a 15 mins drive , make sure there are some corners and junctions, park car , check for leaks the next day , add a touch more if required

Surprisingly this actually help an old car with power steering leek, idk if it’ll permanently seal but y did the job

Previously used similar items to try and cure my power steering leak to no avail. I was loosing roughly half a bottle a month. And was to cheap to take it to a garage lol.Purchased this down to the good reviews and I’m happy I did.I changed the power steering fluid with fresh stuff and added this product. Over a few weeks I did loose some fluid however noticeably less then previously.After 3 weeks or so I topped the fluid back up to the mark and since I haven’t lost a single drop of fluid .Great product and done what a lot of other products couldn’t .

We own a 2005 Nissan Murano, the parts are no longer supported by Nissan so rather than pay £500 for some replacement parts from Europe I thought I'd give this a try. It did work for a couple of weeks but maybe the leak is too large and the screeching is back and the steering stiff once more. Not a big deal as we have bought an electric Mercedes now as the Nissan was close to becoming ULEZ non-compliant. Anyone outside the London area want to buy a nice Murano? Just had new radiator, brakes, exhaust, fan belts but may need a power steering hose!

It worked for me , previously the ground would get damp with oil after a drive and other bits below power steering hose. Now all bone dry , I highly recommend using a syringe to suck up oil and then putting whole can down there afterwards. Hopefully this will be a long term fix and not just a temporary fix .Edit: 2 months on and still not leaking , brilliant.Edit: over 6 months now and still not leaking

Total waste of money; had no effect whatsoever. I wanted to give no stars but it wouldn't let me

The reconditioned steering box of my 1997 Chrysler Voyager started leaking a few years after installation. The first can of Granville fluid reduced the leak greatly (enough to continue using the car without repair), though didn't stop it. Glad to say, afer beginning on use of a third can of Granville, the leak had stopped completely, and hasn't recurred in the last 8-10 months. An excellent result, recommended.

I’ve got a slight leak on power steering that makes it a bit stiff when 1st starting car. After about 5 min it usually free up and normal.I’ve tried several leak stop etc and no good. Tried this and after about 1 week of driving its loads better on steering when 1st starting car

Bonjour il a complètement boucher la fuite, avant d'acheter j'ai constaté que la fuite venez du joint supérieur de axe de direction,et puis j'ai testé avec ce produit est ça. Marche,j'ai vidé complètement le réservoir et mettre le produit, voilà mon expérience et bon courage

Habe nach und nach benutzt hat nichts bewirkt !Jetzt versuche ich lecwec hoffe das hilft.Schade der Preis war ok .

Siempre he dudado de estos productos he trabajado de mecánico y sigo reparando mis vehículos. Pero me sorprendió sellando una caja de dirección que perdía todo el liquido por el eje . Muy contento

Buen aditivo antifugas. Por el momento, resultado satisfactorio.
