Marcus, your situation sounds a tad sketchy here. As Patrick and JC have eluded, P1121 means a new 3 way coolant valve is needed. It's an easy...
I see what your getting at here; blown EGR cooler, coolant back flow into cylinder 4 via open exhaust valve while engine off. Tracksydes...
Complimentary pink coolant on ice for all comers!
I use the F1 rather than the F2 on our family '07 (170k miles) and have for ~50k miles. They both list for $5.41, so I go with the warm fuzzy of...
I totally share your frustration, AV. We hold Toyota to a higher standard but it is a standard they've created for themselves. That's why I hope...
Yeah, unfortunately it's all just thinking out loud, Mendel... @Tracksyde 's dealer diagnosis of "gasket failed, no known cause" is what I expect...
The blown cooler theory would indeed be a great alternative to head gasket failure, but I'm not sure it will turn out to be the case. AV's pic of...
I believe the pack is to go in his 2010, JC.
Don't hesitate to do the work yourself. Drain the coolant, pull the air intake and the pump is right there, albeit a bit of a tight squeeze...
K - manufactured in 2009, looks original for a 2010
+1 on cleaning entire EGR circuit on the replacement engine before you drop it in!! Out of paranoia, I'd throw a new, Aisin WPT-190 water pump on...
Matt, was your head gasket replaced or did you do an engine swap? I'd rinse that engine bay so further driving can determine if you have an...

Hard to know. The "check hybrid system" warning would typically bring on limp mode but the OP only reports the engine related code. Assuming...
There is, but knowing what we know, I'd never want to see it. It's hard to think these heads have integrity enough to tolerate an actual overheat.
Thanks for reporting this. Water pump integrity is a big question mark in my mind with regard to the trending gen 3 head gasket failure issues...
Ed is correct, this is completely normal with regard to gen's 2 and 3 as I've verified with our '07, '10 and '11. None have been neglected and all...
No peer pressure, of course...:whistle:
I should clarify that I'm not saying these blown head gaskets aren't indeed blown head gaskets. I'm just saying that of all the reports we've had...
Aaron, I think what @mjoo is getting at is that the EGR cooler (remember, the engine coolant loop runs through it to create this "cooled EGR")...
