Flashing engine light and then solid

How many miles?

That's the engine coolant reservoir, takes Toyota Super Long Life coolant. Get a gallon from dealership and top it up. There's a good chance you'll be needing the rest before this is done.

And don't you just love it: any old econobox car used to have a coolant temp gauge. You can monitor with ScanGuage II, or a phone app with bluetooth OBD dongle.

I'm guessing this is going to be head gasket failure. Maybe failing water pump too.

 

And EGR cooler? Pipe? Intake manifold small passages?

 

Make sure it not leaking coolant from the egr repair. Sucks if you just paid so much money if the engine is blown....in which case there was a misdiagnosis by the mechanic. He probably installed a new egr cooler and maybe valve rather than cleaning the original part?

SM-G960U ?

 

Edit: Sounds like you had a head gasket replaced and carbon cleanout as well. Not too bad for $1900. Fuel is not the issue. Its too long between oil changes (do 5k mile changes) and a poor engine design - fixed partially by 2015 and reengineered properly in the 2016 gen4s.

The coolant reservoir should not "use" any fluid but the mechanic may have failed to fill it up after spilling some during the egr work. I assume this was not a dealer.

Fill the coolant and carefully watch the level. You will get a temperature warning light if it is close to overheating. Stop within minutes when safe and have it looked at very soon. Any further coolant loss without a visible leak usually means head gasket leakage into a cylinder, often resulting in an occasional severe startup rattle.

 

This is first mention of intake manifold, and yeah it is important: has the last leg of the EGR passages on way to intakes. This should be cleaned as well. Best to replace all it's gaskets while in there. Also, throttle body can be removed and placed out of the way WITHOUT disconnection of it's coolant lines. And cleaning is trivial, no need to replace.

More info in my signature.

I'm a little sceptical they've changed head gasket. Maybe. What does the paperwork say??

 

Kind of hard to clean the intake manifold while it's connected to the coolant lines....

 

Op said he had the egr repaired for $1900 in the first post and also a head gasket job in his followup post. By whom is a question. What they did in detail is also in question but its safe to say he's running again. Even with a low coolant reservoir.

 

So those plugs coils and egr gaskets add up to about $530. How did they get the bill up to $1900?

 

Labour?

The throttle body is connected to coolant lines, not the intake manifold. You unbolt and lift off the throttle body (with coolant lines attached), tie off to something, say inverter, and there’s the intake manifold, no coolant lines attached.

c’mon you knew this.

 

Yes, brain fart for a late night, that I thought about after going to bed....
