    i've used liquid glass with good results. looks like a clear liquid with copper coloured sediment in the bottom. shake it up and pour it in. run for 20 mins ish and drain system (including block if possible) leave overnight then refill with coolant mix. had cars run for 2 years plus after using it to cure head gasket leaks/overheating so not a temporary fix.

    Steel seal forms an epoxy type goo.When I used it as per instructions ie warm up for an hour it almost completely blocked the passage of water to the cylinder head.As it sticks to the hottest parts.It did not seal my headgasket however.
    On removing the head I then had to flush and scrape the stuff out of the water galleries it also blocked the thermostat.

    I think the stuff is useless and would never use it again.

    However I know someone who used it on a Grand cheroke and supposedly it worked he did sell the car shortly after however.....

    Seems you were right. Looks as though it was just condensation build up. Been cleaned and nothing has returned. Water loss has stopped, so guessing that it may have just been the system settling after the coolant was changed. Glad I didn't waste the money now! : )

    i sell loads of k seal at work, people love it its brilliant, one guy told me it cured the head gasket leak on his merc atego truck which was seeping a gallon a day, it cured it after about 4hrs driving...

    just tip it in and drive...

    you sure your head gasket is blown?? had this loads of times (my head gasket has gone as there is white gloop in the oil filler cap and on the dipstick) could just be caused buy condenation build up buddy have some one do a sniff test to be sure if you have water oil mix or vice versa the fluid used in the sniffer should change colour.
    dose not have to pressurise to detect it, you may just have a small water leak and fretting over nothing, even have a pressure test on it to check just take some precautions befor you shoving cures in a can in, i have been in the trade for 28yrs and have had first hand experience of the mess this sort of stuff can cause it can end up being more costly especialy on old cooling systems ie, rads blocked,heater matrixes, and in one extream case partialy blocked water jackets in a cylinder head on a honda ledgend v6, wasnt best pleased as it was a **** to strip and only then did my customer say he had been putting in a water additive for months. just bear in mind that it is only sold as a get me home fix and if your gasket is leaking into an oil return gallery it wont work as it will not stick to oil even if it is passed through the gasket
    buy all means try it, it may be ok for a while but if the gasket is failing then its failing. if your motor is the 16v zetec they are not that bad a job to do. just adving you on the obvious things to check first, example stat housing leaking yes it will stop it and allso poss your stat working too just that i have been there and seen it on several occations. sorry for the negative responce but please do it with caution thanks andy.......

    i use cargo metalic seal up (if you can find it), about 8-10 a bottle.

    i had 2a landy with 7 splits in the rad, pit it in & rove back 20 miles from the off roading event ... cured!, a sierra (1.6 pinto) with porous/leaking thermostat housing, leaking heater matrix & pin hole in a rubber hose, poured it in & drove 6 miles ... cured! we sold the car locally after just over a year & the old boy ran it for aother 2 years without any problems. another sierra (2ltr dohc), head gasket went, poured it in from cold, went for a 10 mile blast ... cured! engine outlasted the body & found it's way (straight out the sierra) into a caterham, the engine only died after the owner did a track day & over revved down shifting, putting the rod through the block.

    if i have any doubts about the condition of the coolant system, i'll put cargo metalic seal up into it. no need to remove the thermostat, it won't block the rad, no need to flush the system before or after ... unlike a lot of others (although someone has offered me 80 for the stick of holts leak stopper stuff thinking it was something illegal ... should i have sold it to him?), i just our this in & leave it untill i'm ready to do a coolant change

    Steel seal isn't too bad but expensive compared to k-seal. (30 vs 9 I think) So might as well go for k-seal!
