Bars 1830976 H1S1L-27 Head Gasket 600ml

Work like magic. Worth money. My ford fiesta 2009 model had serious gasket issue and if I replace with new so it cost more than £1000 but this product work very well and resolve issue. But I suggest to read instructions very carefully and also get idea that how to use this type of product by watching videos from YouTube. My issue resolved in just 1 hour. Work very well and leakage absolutely stop. No smoke or no harmful for engine or anything. Cooling capacity is good.

This stuff actually worked..... I done the exhaust gasses test and changed from blue to yellow after few minutes. Done a full flush on all pipes removed thermostat check was working. Simple to use and understand my 13 year old daughter dis the rest. Pour bottle in coolant tank top up coolant to above max line. Close coolant lid. Start car put heaters on max. Left running for max 30 minutes. Checked topped up fluid again. Disnt over heat like would before thought i try it as garage said 1484.73 to do head and cam belt. Car not worth it.Let cool down. Took for a run after 7 weeks off the road. Temp gauge stayed half way all the time stop in traffic 20 min no movement on gauge or tablet temperature whilst running diagnostic. Had heat back in the car aswel apart from to hot out side to keep on but nice to know its working again. Done the exhaust gas test again 15 mins and still blue not a change in colour..... Will update in few months how its going today date 16/7/23 total time 4 hours 35 mins. Before 30 min max before it would start to climb on temperature gauge. Amazing stuff....

Not only did it not work, it completely clogged my heater core!! I have a pressurized system. It didn't solve any symptoms at all! For the price, I expected some result regardless of how small! I certainly wasn't expecting it to destroy my heater core 🙄

I'm not quite sure my car needed this, but maybe it did .Read instructions and I only needed half bottle, syphoned off that amount from cooling system and poured in, ran car engine plus heating/air conditioning 15 minutes, done. I figured if my car did not need it, it still was a good precaution

So, I have a tale of woe...... Unfortunately I had some work done on my car by someone not up to the standards I would expect. He left me with a water leak that was using 0.5 ltr of water every day. I started using a different garage, but they could not quickly find a leak (pressure test did not highlight a point of leakage, and the chemical tests ruled out a head gasket failure. So my choice was to try this, or spend a lot of money on finding the leak. After researching which sealant to use, I finally picked this one. Something I was worried about was clogging the air-conditioning system. But since I used this, I have not had to top up my radiator at all (several months have now passed) No dashboard error warning and the Aircon still blows warm air when needed. (Just for the record, my car is a 2013 C220 CDI)I am really happy with this, and it really did save a fortune, just in diagnostic charges.

Do these chemicals work, Dont buy them .

Bought this product feeling about 50/50 about the result.Some said it was great, others said it was rubbish.We procrastinated for about 2 weeks, then following the instructions to the LETTER, my husband used it.After about a weeks worth of driving the car, I have to say, it's pulling better, there's no more water leaking into the oil and the shuddering has stopped.So it would appear that, as lo g as you follow the instructions word for word, as other reviews have said, it works.And works well.I believe the gasket was only cracked a bit, so not catastrophic damage, which seems to have been sealed using this.

Was sceptical but this kept my car going for a good 8 months. I knew the head gasket was going but couldn't justify replacing as was more than the car was worth. Bought this a few times and really helped until she finally went to the scrap yard.
