When does the water pump have to be replaced???

And no my water pump is just fine,

I'm just wondering.

When it blows up, usually while you're driving 80mph on the interstate and suddenly you notice your "check engine" light comes on and your temperature needle is pointing off the hot end of the gauge...

That's what happened to me in my old car, somewhere around 110,000 miles :?

The xA and xB have no temperature gauge; only blue cold engine and red overheated engine lights.

I added a temp gauge so I could monitor my engine in case water pump went out or hose or belt broke. I'm loving it. Normal xB temp is between 175F and 180F.

Thats a good idea about adding a gauge. Now for the topic here. I dont think there is any 1 time it will go out. Its just a real random thing depending on a number of factors. My current car is running on its stock water pump & im nearing 120,000 miles & the temp is doing fine. Had to replace the radiator not that long ago, sprung a leak :?.

the radiator in my old car went thru a lot of rebuilds and a few replacements and i only had the the water pump replaced once must of been the Ph balance must of been wacky

jct

so where is the water pump located at with the timing chain or ran off the pullies on the outside of the engine

My friend just had to replace his on his 2002 Cougar. Apparently they have a problem and they tend to give out at 40,000 miles.

Right after the warranty expires. How convenient. But we have Toyotas and they SHOULD last the life of the car!

was told by scion that recommended change was 60k miles

cost about 300 bucks and ofcourse u gotta have labor with it

if u get the extended warrenty, that replacement would be free

hope that info helps

in my old car, the water pump dying was a common problem. if you cant get hot air to blow, then it could be your water pump.

[quote="hornet_on_flower"]You should be using distilled water then! It's only a couple of bux for a few gallons!

Replacement really depends on the car. My Porsche was around 70k and they popped
like clockwork. My SAAB hit 330,000 and was still going strong on the original.
The volvo before that had about 230,000 on the stock water pump.

i was using distilled water thats the only thing i buy for my radiators i give it a 50/50 mix

raWr215

distilled still has some minerals, chemicals are removed, but metal deposites are still with in, so it really doesn't matter

pure water from the distillion process actually involves boiling water, collecting the condensation into another container

Maybe someone knows this answer.
I was crusing at 40mph the other day. I had my laptop hooked up to my Hydra standalone.

I have a turbocharged tC. Running 7psi. AFR of 12 which is on the rich side (street tuned). Radiator Fans are working. Thermostat is fine, I just changed it. Timing is conservative. Temperatures were logged while out of boost.

I did a coolant flush last week. The only thing I forgot to do was bleed the coolant for air bubbles.

The stock temperature gauge needle was directly in middle of Cold/Hot. I happened to notice the coolant temperature was 120-130 Fahrenheit when I checked my laptop. Is that a normal temperature? Just curious, since Ii've never took notice to it before.

I thought tC's had engine coolant temps between 90-110F.

should be around 180 degrees

Does the xA have a timing belt or chain? If it has a timing belt, I would replace the water pump when doing a timing belt replacement, It is cheaper labor wise while it's all apart anyway. I think the tC and the new xB have timing chains.

zA-xB classic, uses a timing chain

[quote="Lonely_Raven"]Yes and no. You guys (all of us actually) should be using the pre-mixed Toyota Super Long Life Coolant. It's already mixed at the proper ratio with deionized water and also has the correct amounts of organic acids (no silicates) to provide the necessary protection to your radiator and waterpump.

It's really not that expensive (I think I paid abou $20 for my last gallon) and since you don't have to flush anything (necessary when switching formulations) it should help cut down on the chances of leaving an air pocket.

Bringing this back from the dead.

I am having this exact same noise, and when I took it to the dealer today, they said this was the problem.

Is there a manual for this, or maybe a DIY around?

Thanks for the help
