What does"watercooled" mean?

[obiwan]

As a newbie, what does "watercooled" mean or refer to?

[Tim]

it means that its cooled with water unlike early aircooled VWs

[mk3pete]

well said timbob

[Preen59]

Not to be confused with flat four terminology, as the later T3 engines were watercooled too.

[WABIT]

hey mate, first off welcome to the forum

OK, the reference "watercooled" is used to split the description of model volkswagens

early beetles, kombi's and type 3's are "aircooled" and dont use a radiator
anything "watercooled" is 1975 mk1 golf, passat, transporter and up to the new mk6 golf and everything on the showroom is watercooled

hope that clears it up abit

To expand further - the watercooled models have a system for pumping fluid (water or coolant) through water channels in the engine to absorb heat, and then into a radiator where airflow causes a heat exchange to occur, reducing the temperature of the coolant.

The aircooled models cool their engine by heat exchange with the air around the engine directly, generally by having fins on the outside of the engine to increase surface area through which heat can radiate out into the surrounding air.

Thanks guys.

to expand further

Water (H2O, HOH) is the most abundant molecule on Earth's surface, constituting about 70% of the planet's surface. In nature it exists in liquid, solid, and gaseous states. It is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. At room temperature, it is a nearly colorless with a hint of blue, tasteless, and odorless liquid. Many substances dissolve in water and it is commonly referred to as the universal solvent. Because of this, water in nature and in use is rarely pure and some of its properties may vary slightly from those of the pure substance. However, there are many compounds that are essentially, if not completely, insoluble in water. Water is the only common substance found naturally in all three common states of matter—for other substances, see chemical properties. Water is essential for life on Earth.[3] Water usually makes up 55% to 78% of the human body.[4]



sorry

[gareth_oau]

out of curiosity are the new beetles watercooled?

if so, how come we dont see them on this forum? Can I presume they tried, but we laughed them away?

[Tim]

the new beetles are based on a mk4 golf I believe just with a retro funky body. they use normal watercooled engines.

and cheers professor Tim

my body is typically around 59% hydrated, which is quite high relative to the average population which sits around 55% - elite athletes hover between 60 and 65%

most of the members here have very little water in their systems, I hear its mostly beer

[balkanac]

I have a lot of coffee in my system, i rarely drink beer. I love coffee!!!!!!

Cool.. So i'm an Elite athlete then?

no Preen, you're an exception to the rule - you're just WET

And that means they have their engine in the front, not the back like the old beetles.

There are a few owners in the Mk4 section I'm pretty sure...
