What does a Dephaser pulley do?
What does a Dephaser pulley do?
The dephaser pulley is a special type of pulley that allows the timing of the timing belt to be increased or decreased, depending on operating conditions. It’s most commonly found in Renault vehicles.
How does a Renault Dephaser pulley work?
Dephaser alters valve timing to help maintain good torque across the revs and improve engine/fuel efficiency. If it buggers up, as it will do, it becomes very noisy on start up and can cause starting problems and loss of power. You will still be able to drive it however.
What is a camshaft Dephaser?
Renault Clio: Camshaft dephaser: Function Its role is to modify the valve timing. To improve cylinder filling at all engine speeds, the engine is fitted with an inlet camshaft dephaser (1). The higher the engine speed, the later the inlet valves must be closed.
What is a Clio Dephaser?
Yes its got one, instead of a normal pulley on the inlet camshaft you have a dephaser which allows the timing of the cam to be advanced/retarded depending on operating conditions.
What does a camshaft Dephaser solenoid do?
What does Dephaser mean?
the dephaser is a internal part of the engine and not an ancilliary part. When the cambelt is changed a dephaser pully is not part of the cambelt kit. We regard the Dephaser as a mechanism which improves the filling at high speeds.
When did Renault start using de phaser pulleys?
There are 2 types of dephaser pulley the ones fitted to the 1.8 F4P and 2.0 F4R 16 valve engines. They have been fitted from around 1999 in various different Renault models so more of these around. These usually only start to get really noisy once the engine has warmed up and are classically described as the engine sounding like a diesel.
Are there any dephaser pulleys for f4p engines?
Many thanks in advance! There are 2 types of dephaser pulley the ones fitted to the 1.8 F4P and 2.0 F4R 16 valve engines. They have been fitted from around 1999 in various different Renault models so more of these around.
What kind of engine sounds like a dephaser pulley?
On some forums and threads people have said that’s definitely the dephaser pulley on the way out. From what I can tell, below a certain number of revs (2000?) the engine sounds like a diesel, or a tractor, often with a ‘clattering’ sound, and often stalls.
When does the dephaser cut out in a Renault?
When the renault tech heard it he was suprised it didn’t quieten once the component had warmed or filled. Whilst the dephaser was “failing” the engine would cut out when cold, run rough a lot of the time unless above 1500-2000 or so rpm.
