EGR & cooler cleaned , @ 150k miles , was bad

Hello just sharing my experience on EGR & COOLER CLEANING ,

2014 gen3 Toyota Prius right hand drive from uk
I managed to take apart & put back without removing the windscreen cowl & the bottom engine cover ,
There was plenty space , note this is a uk right hand drive model ,

I finally got it done ,
Could not have done without you guys tips ,
Mendels tip about draining 2 quarter coolant , & the bolt from hell ,

I brought a used cooler of eBay £20 & cleaned before start ,
Everything including egr & cooler completely caked , few photos to share , had to finish in dark in end

nut from hell I brought a angled flex head 3/8 ratchet &12 mm deep socket once figured out it came off easy , no ext for ratchet just reached ,
All rest was straight forward , 1 hiccup I dropped the rear cooler gasket , I forgot about it until too late, it dropped down bottom , luckily I found it near the engine oil service window, few clips & got it back about 1/2 hour looking ,

Nut from hell couldn’t remove the stud in situ with everything there ,
I did remove it after & left it off for good ,
That area too tight ,
Few small cuts on hand.
I did the manifold 5-6 months ago , looks already dirty why is that ? That’s for another day much easier .

About 4 hrs work time including bleeding which took about 1 hr on maintenance mode for fan to turn on twice ,left cap open until fan turns on , maybe that’s why !

thank you everyone in this forum , you guys are gold honestly , really appreciate.

 

Thanks ,
Mendel yourself &
Nuts about bolts

great tips for helping & it gave me confidence to do it myself,

I am no mechanic,
But I don’t trust these street garages

I did the water pump as well in 2 days ,
As I shared the impeller was cracked & a lot harder to turn ,
Slight tingle my head didn’t change the thermostat, Toyota one expensive, didn’t want aftermarket,
Recon I should change it as preventative??

But Mendels recommendation from amayama £30 sounds great , 2 weeks deliver might try that


I hope my overheating I was having has been solved ,

 

Hello
I’m not sure which is the spigot vent ,
How to know for sure when air is out , this is new experience for me , but I heard get it wrong & engine overheat

also I’m wondering the lower cooler bracket will it make any rattle noise ,
& with cleaned improved airflow does the ecu need any resetting just wondering,
I have got a lot more to do like spark plugs not changed ,& transmission oil & brake fluid all to do ,
Will see how brave I feel

only done some short trips feels little better

thanks

 

Hello guys update
Been driving few days now
Car runs a lot stronger now ,
However I’m experiencing some very light lumpy while maintaining speed about 5-10 % lumpy , around all speed ,didn’t notice this before
Not a minor issue but is bothering, could be my mind ,
Could it be the intake manifold !
the egr I didn’t open the spring when cleaning
Manifold clean about 5 months ago but looked dirty this time ,
Should I disconnect battery to reset ecu ?

thanks
