does ur pipe go hard? ;)
« on: May 17, 2006, 18:48:47 PM »
hi, lol uve probably never checked before but after driving when the engine is at normal temp are both the big coolant hoses harder to squeeze than normal for a RED TOP?

mine are brand new and go really tight just wondering if this is normal, a local mechanic said it was but i wanna check with the proper experts :)

They would be harder to squeeze as the system would be pressurised. As the system cools the pressure drops.

Perfectly normal, all cars do this  when hot. Pressurizing the cooling system raises the boiling point of water. If you ran your engine ,say with the  expansion tank cap of it will soon boil over and very quick with it (no, dont try it, just take my word for it) youll have nice soft hoses, no coolant and a well cooked and bolloxed engine....
ALARMED!....You will be, this car is owned by the most hairy arsed b*stard of the worst kind.
