Cooling system bubbles, help!

It could use a couple tanks from the overflow bottle before it works all
the air out. Just make sure it has fluid to suck back in.

Most vehicles use about 1/4 to 1/3 of the overflow bottle between the
fill cold and fill hot marks on the bottle.

If you use water in a hot country, you 'will' have way more liquid
puking out hot or when you shut it down than a normal car!

Water boils at 212 F. A 50/50 mix with coolant will boil at about 250
F, about 265 F with a 15 lb rad cap.

Hi Mike,

Ok my mechanic is working with the car today, adding more coolant to
the mix since it gets pretty damn hot down here in Panama. Also he is
adding a bleed screw to have it since my Eclipse doesn't come with one.
I also have a 9lb radiator cap and that might also be faulty. Should I
get a 13lb cap? My engine is a V6 engine.

Also, a couple of years back my mechanic removed the heater pipe just
to keep the water running around my cooling system cause in Panama I
didn't need to have the heater. Today I asked him to put it back on
since I believe it should be as it is originally..

Let me know about the cap,

Regards,
Teo

You know, you can get an inexpensive Haynes Manual for your car that
tells you all those basics. It is not the best manual, but it is cheap
and gives all the specs. If you can't find it locally, you might try
he http://www.haynes.com/

My engine runs on a 16 lb cap, I have no idea what yours 'should' run
at. To weak of a cap will cause troubles though.

I think you have figured out how to get the air out though. It just
takes a bit of patience on some vehicles. A few good cuss words don't
hurt either...

Did you check the intake manifold for cracks?


It's possible for an exhaust crossover passage to leak into
the water tubes.

I have seen this happen on Jeep V-6's before.
It's uncommon, but it happens.

my experience has been when winterizing an auto's cooling system is to
drain the old coolant, inspect all hose, replace if necessary, and check
clamp

bolts for fitness. remove the thermostat, and fill the system with water
and add a

can of flush, start the engine with the heater and fan on in max heat
position,

and run until all the air (bubbles) is out of the system. then put the
radiator cap on

and run for ten minutes. let cool down, flush with clear water,
re-install the

thermostat, fill the system with 50/50 coolant / water, start the engine
and run

with the cap off until the air bubbles are out, and the coolant settles
down, then

top off with coolant, service reservoir, put the radiator cap on, and
go. dispose of the
old coolant in a safe manner. check later for leaks.

radiator caps and hoses should be replaced on a periodic basis, at least
every 3-5 years.

drain / refill instructions are on coolant jugs. and there are in some
cases special coolants for different cars.

Given your posts here, I'd say that the above statement is a contradiction
