^^I strongly agree..

also, man.. buti nalang na uwi pa ang kotse!! anywayz, running an engine (specially gasoline engines) w/out a radiator cap is a NO NO! since it will cause overheating.. which can lead to all sorts of preoblems, like a Blown Head Gasket and a cracked Cylinder Head.

pero pag Diesel engines... ok pa.. since I remembered driving one of our Mercedes-Benz 300D for about an hour.. then later found out it didnt have a damn radiator cap!! good thing though Diesel engines runs a little cooler than Gasoline engines (due to lower internal combustions)... making Diesel engines almost not to overheat at all! LOLz!



aite, peace.
