Sorry for the late review!

I bought k seal more than 3-4 weeks pour in my 12 years hardly drive iswara that recently "semput" on every cold start takes about 3-4minutes to "warm up" when this happens you know lah white smokes appear and that sickening water lost believe it or not i change/top up my coolant every 4months because of water/coolant lost..I bought the k seal after 2 days of changing coolant..

the improvement i see/feel

1. Car no more water leak/lost
2. no more hard core "semput" on cold start
3.no more white smokes

Thanks bro! great product eventhough it doesnt cure all problem but these little thing gave more comfort!
