Shown on a 2004 Volkswagen Jetta GLS with a 2.0L BEV engine, but this works the same on many related models, years, and engines.

On 2001 V W beetle GLS water kept evaporating from radiator all the time.
What should i do?
u might be on to something there….my jetta is having the same symptoms as
in this video but was running fine until a plastic hose piece broke and
sent coolant everywhere….now that i replaced the plastic part and re
filled my car with coolant its still overheating. my car was just fine lol
hi i just watched your video and i have some questions. i have a 2001 vw
jetta gls 2.0 and my car was running just fine until a little plastic piece
broke that connects the bottom radiator hose with 3 other hoses that
distribute back to the motor. i replaced that plastic piece and filled my
car back up with coolant but now when i drive i get the same symptoms as u
described. im confused because everything was fine until that stupid piece
broke. i hear the coolant flowing through the engine
These come to mind: Blown head gasket, bad water pump, belt that is turning
water pump pulley slips, a hose that has peeled on the inside causing
obstructed flow, clogged radiator (requires a back flush), electric
radiator fan does not turn on when engine is hot, and others I can’t think
of at moment.
what if the radiator hose is hot what are other major problem causing the
car to overheat? btw: coolant level normal. also my etc sensor goes off and
its the second one.
@cliffsplace Although bubbles in the coolant reservoir could be evidence of
a blown head gasket or cracked cylinder head, the more simple explanation
is excessive heat inside the block. If the water pump doesn’t move water
through the engine, the water trapped inside the block will boil, and the
steam that is produced needs to go somewhere.
thanks,god bless you
Yes. As long the temperature gauge is in the middle, even going up hill
slowly on a hot day, you are likely to be in good shape.
Well, perhaps a similar characterization of your videography skills would
fit. Perhaps not certified, but hard work with know-how created some
excellent videos. I know we would not have undertaken the timing and water
pump on the 2.0L VW without your effort to construct a very good video of
the process! Thanks again.
@cliffsplace this is not true the thottle body is heated/cooled by the
coolant and the hose going to the top of the resevoiur is the treturn of
the coolant. also to the video maker. better flush that shit good to make
sure you get all the chunks of impeller out.
I noticed corrosion around the coolant flange assembly, so I had it
replaced. For nearly a month it ran fine no issues besides the temp gauge
reading that was reading roughly 2 lines above VW avg 190. Not even a month
later the car makes a funny noise and starts steaming and spraying coolant
all over the place. I took the car on Monday and the flange was cracked
they replaced it, along with the o-ring from the sensor. Tonight the temp
light comes on and now no more coolant. Help please!
How do you tell if it is really your water pump without taking it off? Is
is sporadic when these actually fail or break down (since the fins are made
with mere plastic), my car is an ’04 VW Golf with less than 55k miles on
it. 🙁
Hello, I have a golf that recently overheated this weekend. What kind of
tools would I need to do a job like this? I noticed that a hose was blowing
out steam and the car stunk like burnt coolant. I have a golf 2001 1.8
Those bubbles are from a blown head gasket or a cracked cylinder head.
awesome. thanks dudes!
If my temp gauge is in the middle at all times am i good? it never passes
the center…I just bought a 2004 jetta with 58,000 miles. and i cant even
figure out where the coolent goes.
Did you guys have problems with the transmission and idle? The car every
now and again will fail on me, and die, or have no response with gas pedal,
It will go crazy and wont shift gears either. Have had this happen on me 4
times now.
Thanks for the info about the different types of plastics. Sometimes, metal
is the safest way to go.
Very helpful – Thanks!
What the hell happened to the old water pump?
Guys, a few hours ago, after driving for about 15 minutes at night, my
temperature rose to about 3/4 of the gauge, but after going down a slope
for a couple of minutes w/o using any gas, the temperature went back to
normal (190 degrees). There seems to be enough coolant, I don’t see any
leaks, and the main radiator hose was quite hot. Could it be the thermostat
or the ECT sensor?
It sounds like the crankshaft angle sensor is bad.
Not yet. I can’t believe I did that. Sadly, nobody in our home garage is an
ASE certified mechanic. The good news is that we get the cars fixed at
little or no cost with know-how, hard work, and many errors.
Thanks for the video. Has anybody given you abuse for having your hand on
the air cleaner access duct when you are discussing the upper radiator
hose? Funny. But still appreciate the video!
