How do i get to the tappets on a 100 series turbo landcruiser

I have a Toyota Yaris 2004 plate. The cold light stays,the fan kicks in and stays on, but the cold light does not go off. Help please. regards M Barrett

well it runs,,,,,
low power on a diesel is
1: low compression
2: bad fueling
#2 can take forever to find, if you dont know what engine it is or what fuel system was used.. no country stated, so cant guess
read the wiki on land cruiser and see what you have.
we dont know.

series 80?
series 100,200 ??? what?

• 4.5 L 1FZ-FE I6 gas
  
• 4.7 L 2UZ-FE V8 gas
  
• 4.2 L 1HZ I6 diesel
• 4.2 L 1HD-T I6 turbo diesel
• 4.2 L 1HD-FTE I6 turbo diesel
• 4.5 L 1VD-FTV V8 turbodiesel

one of those last 4? engines?
once there, we try to find out how it works. each varies.
can fix engines with out knowing exactly what it is, and the injection system, used.
cant.

possible air still in the pump so bleed at the pump

I want to change the engine oil in my 200 series cruiser how do I get to the sump plug & filter.

Landcruiser 100 vx, 2003 model with engine number 1HD-FTE is not starting, I've found out that the fuel pump, starter, battery are all functioning well. Where next should I look at.

Track down Toyota publication RM184E - a search of the ih8mud forums is a good start to finding it.

check ignition timing , maybe is advance

The 100 series td is boost limited for 1st gear , this was a factory design to stop consumers getting overexcited at the traffic lights etc! If you think you are getting no power or boost in first (which would be odd) then connect a boost gauge to the turbo pressure vsv (vacum switching valve) on the intake manifold to see what sort of pressure you are getting.
All this can get a little bit involved ie type of motor 1hdt,1hd-fte etc etc, repost if you need further.

the rocker cover has to come off so if turbo is in the way isay yes
