Hi guys/gals,
I still drive my old 95 GS 300 (Mark I) and still love it. Have a
Prius on order (company car, somehow would not let me get a LS600h or
even a GS450h) but still want to keep and maintain the GS.
I had the radiator replaced last year, after it left me stranded due
to acute water loss. Well, after 12 years is not that bad, I guess. As
of the last couple of months (not sure if it was from the start since
the replacement or not, didn't notice anyway) I can hear a few seconds
of gurgling when the car starts. I am pretty certain that there is
some air in either the cooling system or in the heater core. It
disappears after a few seconds, does not always happen and the
temperature is always fine, as it should.
When I had it serviced for it regular maintenance, I asked them to top
up the cooling fluid, if needed and get rid of the air there. This is
not a Lexus shop mind you, but they do service a couple of Lexi and
other (relatively) modern Japanese motors. Have never had any
complaint about them, seem to do an honest job, not over asking, not
pushing any unneeded services or jobs. They did my tyiming belt and
more.
In this case howvere, they had to admit not being able to get the air
out. Somehow they had been looking for a valve or something to release
air from the system, but could not find any.
Are they missing something? I also read somewhere that the best way to
accomplish this task is to place the car on a slope, nose/radiator
pointed to the highest point and then just let it run for w short
while with the radiator cap removed. That should get all air to the
top of the system and get it done. Is that correct? I mean, in that
case, I could probably do it myself, right? Taking precautions that
the engine should be cool, always making sure that the hot coolant
does not spill where it shouldn't and such...
Thanks in advance,
Patrick
