Coolant loss after cat lock fitted

I've a gen 3 persona sitting right here no one touches it ever. Where the cat sits n plates. Bolt up to chassis they're no coolant lines metal or rubber that I know of right now. It's raining out so I cannot easily crawl under and look again . I'm changing out engine n trans in about 3 weeks. But it's a stretch fo sho. Everything out back of vehicle is elec fan cooled by air flow . No coolant!

If it is low on coolant, there is a leak. And since you can't find out outboard leak, it's probably
the head gasket.

 

Yup and you're sitting at about the exact mileage for this to occur .JDM engine time don't waste time with meccies to repair . Replace with low mileage take out . Never touched by the illicit US salvage market . It's a very crooked racket.

No market is safe, theives are everywhere.
If you catch the gasket early, which you might have done, you only need to replace the gasket.
And make sure you clean the EGR Circuit. The cooler and intake manifold if most important.

 

Make sure your mechanic is well versed in modern engine technology and that he checks the piston crowns very carefully for cracks fishers and even holes I had a professional mechanic put back together a 2ZZ engine with a Fisher crack in the top of the piston that was an 800 and something dollar job that if the guy would have sent me pictures of the top of the piston crowns like I had requested I would have caught this and it would never have been reassembled I had to pay this idiot for his shoddy work and non-good comprehension of what he sees and that's what you're stuck with when you're dealing with people that claim they know what they're doing if they're under 30 you better have a real good eye on these people or somebody that knows what's going on has a real good eye because it's not like what it used to be people don't care about what they do anymore All they want to do is get paid that's why they like to pour stop leak in and charge you $2,200 etc we are living in a shit time basically You either need to have a friend in the business that's really a friend not just somebody you smoke with etc because you will get taken even at the Toyota dealer nobody is honest today they are all hiding behind the fine print of their companies every one of them I'm telling you every one of I do business with companies all over the United States small automotive shops etc I know what's going on but don't take my word for it You get to find out every week from post like this and from post all across the United States about this kind of nonsense The ripoffs are so high right now it is actually probably cheaper just to replace the vehicle and get out to be honest about it if you got a good hustle or any of that cars are the least of your problem they're too easy to come and go

tombukts: You REALLY need to use periods, comma's, and paragraphs. It's impossible to read or understand you.

MathewJG: You said you went to a Prius shop, or someone who works on them.
It seems that shop works on a lot of Prius'. So perhaps they do good work.
I would get a quote from them for a headgasket replacement.
If you catch it early, the head should not be warped.

It will most likely be a lot less than from someplace where you can't verify where they engine came from
or how many miles it has.

You give no location, so we don't know where to direct you to any known reliable Pius Techs.

 

Did anybody get under the car and look for leakage from the exhaust heat recovery system, right behind the cat?

 

I'd be looking at 45 and 46 C's

@mathewjg how many miles on it?

 

Probably so those plates are going to be in the way of the catalytic converter and those hoses that connect to the pipes coming out of the catalytic converter are going to be up under those plates protected That's probably how they got knocked loose in the first place probably had to rotate a clamp or something

SM-A715F ?

 

If you can look under near the converter is you may see the coolant leaking.
I guess it would depend on how much you can see with the cover there..

 

If was a water leak anywer near exhaust I'd think you'd see water smoke steam etc SMELL. That sorta thing

The coolant still has to be going somewhere though.

If it is leaking out of the exhaust heat exchanger, there are puddles under the car and little pink droplets hanging off the cat shield.

If it is leaking into the exhaust heat exchanger, there are big glorious clouds of white exhaust that smell sickly sweet.

Has anybody formed an opinion where the coolant is going yet?

 

Perhaps they didn't attach the coolant lines correctly, or they cut them.
Or the converter is cracked...

Seems like they place that install the shield should be repairing it for you, at no cost.

 

if there's a puddle, there's a problem
