3-Way Coolant Flow Control Valve Water Valve Replacement

Most mechanics won't do that, or at a minimum, will not warranty anything.
Yes, that one you show is the Chinese imitation.
The OEM assembly can be found at some Toyota dealership online stores for about $120.
You get what you pay for with things like this...

 

I would say pay the $120 for the factory original You might could buy it online pick it up at the store and save 30 bucks I'm not sure of that or take it off of another junk car It's really easy to change won't take but a minute literally takes longer to take the plastic off. And that's about it The Chinese imitations will fail regularly.

 

Nope nothing is happening Just change it ASAP and you should be fine You don't want to drive around all summer in the high heat with the thing acting up but you just need to get it changed It could but it's highly unlikely until it gets real hot outside and you're taxing the cooling system so just knock it out before then

 

Look man the coolant control valve is right in front of you when you're standing in front of the car Just take that plastic black shield up that goes around the hood latch and all of that You don't even have to reuse the clips just rip it up you'll get new clips You should have a box of them anyway in your car then the coolant control valve is right there to the side of the driver headlight and straight down there's four hoses whatever going to it You need a long pair of angle needle nose that's the best thing to squeeze the clamps and push them back behind the barbs then you twist all the hoses and then with your really good at it you can pull all the hoses off whip valve out . And plug up all the hoses on the new one without losing hardly any coolant but forget that for now and don't forget to unplug the electrics to the valve the plug. But it's really silly easy If you can change the flush valve in your toilet you're well on your way to doing this job and just think how you'll feel saving I don't even know what $2,877 are you kidding me there's no way you can make this take much more than an hour. Take a look at some YouTube videos be shocked. I can't help with what people charge in your area for car repair but you can The coolant and whatever's going to get on your hands is not going to hurt you.

 

Along set of angled needle nose will be used many times in your life Don't sweat the $13 at Walmart or whatever

 

Yes, that is a genuine online dealer and a genuine part.

They don't know what they are talking about. As you know your car drives just fine. This is not the engine coolant pump. They might be able to replace the valve (it's not rocket science) but, just to be safe, you should show them the location of the coolant flow control valve on your car.

 

Good Lord in the morning well whatever you decide it's all about you and your car It's unfortunate you can't find a mechanic who doesn't work at a shop and have a shingle hanging over the shop and has to charge $100 an hour If you watched a mechanic from craigslist who comes to your house and do this in your driveway you'd be stupefied I guess because this is one of those repairs it's so easy and goes so fast that you have to go around the corner of the person's garage where you're working and smoke a cigarette and diddle around for a while because you get done so fast it's hard to tell somebody it's $185 and you've been there whopping 9 minutes and 34 seconds but such as life I guess till it happens to you directly and you see it with your own eyes well then things are seen differently and sometimes that is unfortunate and costly but hey if you don't think so that's all that matters $850 I'll even supply the coolant control valve all day long. It's funny how this is a real male problem too women are the first to get in contact very quickly and know that something's not right and then I just show them and they're like my God I could have just gone to Walmart and bought one pair of little pliers to keep in the trunk along with the screwdriver and a quarter inch drive socket set and I can do most of this stuff to my car in minutes oh my God yeah it's that enlightening. I guess that's why not a lot of women spend a lot of time in places like this or something along those lines. because they're quick to suck up the advice or something where guys seem to hem and haw over I'm not sure what .

 

yeah $900 is stealership price.. this job can be done by a mechanic in less than an hour charging you the part and some lost coolant (plus bleeding) and the labor. I did this twice on my Prius both have aftermarket (Dorman, etc) and they will leak or have some electronic issues (Dorman didn't leak but the electronics failed) Pay for the Denso part which is around $100, save you from doing it again.

For a DIY I consider this 5 out of 10, not that easy and not that difficult.. for sure it can't be done in a few minutes. The lower hose is hard to reach at and remove the clamps, I have to remove the hose from the coolant canister (dumping more coolant) which is easier and you also have to disconnect the big radiator hose on top to make room. You should at least know how to bleed the system otherwise it will overheat. You also need an OBD scan tool to reset the code.

 

Nonsense, the $1500 Prius that I recently bought has this problem for very long time. It will cause you not to have heat in the cabin during winter and probably the canister not having warm coolant to warm up the engine fast (for emission purposes)

 

The trick is to make it quick as you have plugs male and female to block off pipes and plug up hoses It is that simple I have them on my tool tray because on a Prius you're always disconnecting some stinking coolant line from something inverter radiator CHS tank blah blah blah so if you're prepared for those things then makes everything real jiggy. If you're not and you're running to find crap while you have a hose on done leaking crap on the ground well there's always that. That is why some people fly a desk and do it on the web.
