HYPER-SEAL ULTRA SEALS AS STEEL - HEAVIEST HEAD GASKET LEAKS REPAIR

Works great used it before and had no problems

i am not a hobby mechanic bought this cause cheap price but paid in kind,first of all seller listing does not have detailed instructions l am pretty sure thats on purpose but what l dont like about this product is it does not work or should not be used with anti freeze that means draining all coolant in my case l had to flush 4 times from radiator drain plug didnt want to drain from block too tedious so l bought loads of distilled water,the other instruction for any engine with back pressure is remove spark plug and run whole process without it,l bought to use on bmw 5 series e39 and always need fan blower on when bleeding but this isnt recommended for this product because of its muddy sludge make up definitely will block heater core along with any other components susceptible,i wouldnt recommend l am actually getting steel seal

I used it on my tractor and wasn't sure if it would work but I thought I would give it a try, I used it as instructed on the tin and it worked perfectly, I am pleased I will defiantly use it again,

Unfortunately for my car the item didn’t work. However, I complained to the seller and they answered me promptly.

Used this product on a blown head gasket.Before using the product. I could not drive more than 5 miles without car overheating steam and total loss of coolant.I used the product and all symptoms of the head gasket failure have disappeared.So far in the 3 weeks since I used itNo more white smokeNo OverheatingNo Coolant Loss.Genuinely Surprised and Amazed.

Didn't work

Although sceptical at this product, follow instructions to the letter and hey presto !! It works, very pleased with results !!

wasted £30 does not work, the guarantee is a farce, don't bother buying this product
