 both the anti-freeze and  cooling
properties  will  decrease,  affecting  the  engine  adve rsely.  For  these  reasons,  be  sure  to  maintain
the  concentration  level  within  the  specified  range.
2.  Do  not  use  a  mixture  of  different  brands  of  anti -freeze.

as  follows.
1.  Check  the  engine  oil,  and  if  required,  refuel  or   replace
it.
NOTE
lIf the amount of the engine oil is insufficient, ai r will
be  sucked  in  from  the  oil  strainer  and  mix 
 the oil
passage.
lIf  the  amount  of  the  engine  oil  is  more  than  the  sp eci-
fied  amount,  it  will  be  stirred  by  the  crankshaft  to
make  a  lot  of  air 
  in  the 
l If  the  oil  is  deteriorated,  it  will  not  easily 
from  air  and  the  amount  of  air’  mixed  in  the  oil  wi ll  ,
increase.
If  the  air  which  has  mixed  in  the  oil  due  to  the  ab ove
causes  enters  the  high  pressure  chamber  in  the  lash
adjusters,  the  air  in  the  high  pressure  chamber  wil l  be
pressurized  during  opening  of  the  valve,  which  caus es
the  lash  adjusters  to  shrink  excessively,  and  an  abnormal
noise  will  be  generated  when  the  valve  is  closed.  T his
is  the  same  phenomenon  as  the  one  when  the  valve
clearance  has  been  excessively  adjusted  by  mistake.
In  this  case,  if  the  air  which  has  entered  the  lash   adjusters
is  bled,  things  will  be  normalized.
