Aracımda 3-4 günde bir 200ml civarı su eksilmesi oluyordu, ustam bu tip bir ürünün durumu kesebileceğini söyledi, denemek için aldım ve uyguladım, şimdilik su seviyesi aynı görünüyor, eksilme olmamış gibi. Yalnız, alışveriş sayfalarında Türkçe kullanım yanlış yazılmış. Motorun ısınmasını bekleyip sıcak suya konulması gibi bir durumdan bahsediliyor. Nasıl yapacaksınız? :) Ki ürünün arkasında zaten "add to cold cooling liquid" gibi bir ibare yer alıyor. Yani soğukken soğutma sıvısına ekleyeceksiniz. Kalorifer açmaya çok gerek var mı bilmiyorum, maksat araç optimum sıcaklığa ulaşsın, fan açsın ve ürün tüm sistemde dolaşsın, minimum 10dk dolaşın uyarısı bu yüzden.
