I am interested in 3l engine
1. Confirm cylinder head for 2L & 3L can be used on either engine blocks.
2. How do I determine if Four (4) Oil sprayer in each piston linners in the engine block is bad?
where do you find a maintance manual Hiace 1992 3L diesel
What is the top cover torque specification for 3L engine
Engine head torque for Hilux 3L engine
could you please send a list of those involved in sales of 3l engines in uganda
could you please send a list of those involved in sales of 3l engines in uganda
Is there any possibility to retrieve the manufacturing year of a 3L using the Engine serial #.
Thankyou your information is very helpful.
Am happy to be in touch with you,thank you.
Dear Sir.
You need your quotations for diesel engines 2L,3L and 5L and any quantity available to you and it will be exported out UK.
Thanks
looking for chassie frame dimention for toyota prado 3l
My 3l engine is overheating(boiling) especially when it is loaded to capacity. It powers an Hiace which is carrying 16 passengers. It was overhauled and still on standard. The radiator is a transverse one and was cleaned though roughly and the water pump is working normally.The radiator cap was replaced.
Let me follow your comment I’m also having the same problem.
Mine too anyone with a solution please?
Please keep me updated with new ones
What is the weight of the 3L engine?
What is the position of exhaust and intake valve on toyota 3L engine head?
My 3L engine just started shaking as i accelerate and loss of power, what could be the problem.
Hello, can I replace 2TR engine by 3L engine in Toyota Hilux vvti?
THANKS FOR SHARING THE TORGUE SPECIFICATION FOR 3L ENGINE.
IT WORTH IT FOR ME TO READ AND DO WHAT IS WRIGHT FOR MY ENGINE
hi there,
engine over heating?
flush the block, radiator, use toyota thermostat, radiator must be very clean,!
ur 2L will last decades, if you:
change the oil at 5ooo km.
failure to change and maintain oil at correct km ur number 3 big end will destroy ur engine!!
change oil filter at 10000km.
change the cam belt and tensioners at 100000 km.
change the coolant and power flush ur block at correct period.
check fan belts and adjust as required.
make sure ur radiator viscus fan is working properly..
the air filter must be cleaned at 5000 km depending on road condition or renewed.
edit: change the coolant pump,thermostat and radiator cap when you change the cam belt..
7621 hatcliffe borrowdale harare
all of my crankpin diameters are approximately 55mm. I dont understand why this is if the specs here say 52.988-53.000 mm. why is mine 2 mm larger in diameter? my engine is designated 3l ln86r.
what is the reccomended torque settings for the fuel injectors and the fuel rail holder bolts?
