2010 Prius Rattle/Knock Help | PriusChat

 

Did you have any engine lights come on?, mine doesn't. I'm going to ask my mechanic to check this out on my 2010 prius. The shuddering is really annoying. I've changed plugs, coils & ran injector cleaner through a full tank. The problem is still there & this is worth a try. The prius is such a great little economical car & the random shuddering is bloody annoying.
Thanks for sharing the info.

 

anyone can help me please
The #7 was EGR Cooler and it’s really hardest to access,
How do you proceed to remove #7 -

 

I use this video

 

That video shows all the steps. What are you specifically having problems with? The nut-on-stud on the bracket on the underside of the cooler? It is very hard to access, lots of cables/hoses in the way. I tried various sockets, and extensions, finally got it. You can leave it off when reassembling. Too: if you drain 2 liters of coolant (at the radiator drain), into a clean container, you will not spill any coolant when removing the EGR cooler/valve. Just pour the coolant back into the reservoir when you're done. And if removing the throttle body, just leave it's coolant lines connected.

Some tools worth having:

E8 Torx socket (mandatory)
E6 Torx socket (optional, but good to have, to remove the throttle body studs from intake manifold)
3/8" ratchet wrench, regular and long handle, flex head, you can never have enough (or 1/2 plus reducer)
1/4" ratchet wrench, or 3/8" to 1/4" reducer
Ratchet extensions: you can never have enough
Long needle nose piers, straight and bent tip
Ratcheting 12mm box wrench (optional, but makes disconnection of the EGR cooler from exhaust easier)
Torque wrench (3/8" and 1/4" both good to have)
Floor jack and safety stands (or ramps): basically some method to raise front, if you need to take underpanel off, which you may need to, both for access and to recover dropped items.

 

Did you solve the shudder problem?
