Can anyone tell me the function of the water

thermo sensor. Cause i broke mine and the

auto parts stores do not know what I am

talking about

Where is this again? i get those darn sensors mixed up there are so many of them. Is it on your radiator or your dynamic chamber?

Take it in too them, it just unscrews and unplugs. If they still are dumbfounded take it to a mazda dealer. ( do that last though!)

The water thermosensor is behind the water pump. It tells the ECU the coolant temperature. If you can't get the Mazda sensor then try Pep Boys. They sell one made by Borg Warner that works just fine.

Yes, it is behind the waterpump.

I have been having overheating problems. I changed the

T-Stat, the fan clutch, the Radiator, and the waterpump.

I seam to have cured the overheating, but sometime during

these repair's I broke the water thermo sensor.

now when the car is cold i have to crank it over for a few

seconds before it starts then when it does start it reves up

real high and then dies, it does this a few times before it

stayes running. when it is warm it starts no problem.

So I am hopeing that this broke sensor is the problem.

Also the new radiator i put in has a rad cap and resivor hose,

the car allready has these, so should I plug off the Resivor

opening thats allready on car or the 1 on the new rad?

You should always keep the one that is at the highest point because if it would have air in the system it'd stay there and then would be flushed out while the engine is warming up. Or keep them both using a tee fitting.

thank you, I was wondering if it would be okay to put in

a TEE.

As long as you keep coolant in the tank so they can't suck up air instead of coolant when the engine is cooling. You have to anyway. :sigh:

The ECU gives the motor more fuel as the coolant temperature decreases. So right now your motor probably isn't getting enough fuel when it's cold.

OK Thank You. I was wandering why it was able to turn over

for more than a second and not flooding. Cause normally if

the car doesn't start right away it floods. so i would say not

enough fuel when cold, would be right on the money.

once again I thank everyone for all the help.

Does anyone know were I can posibly order this sensor

none of the auto parts store's in my area seam to have it.

< No Mazda dealerships around you???? Dealer is the same price as most vendors, so dont bother trying to shop around for such a small thing.

Mazdatrix will have it in stock.

Nope tried Mazdatrix. Find Nothing, JUST LIKE EVERY OTHER

PLACE I TRIED. Do you think possible there could be another

name for this part ?

Just call Mazdatrix and they'll help you.

Yes, call them, it may not be listed online, or in a catalog, but I bet they have it. Heck, youre in California, how far from them?

Nowadays nobody wants to call anyone. They always want to check a website.

< AAHH to be young in the year 2002!

I'm considered young, but I've been told that I act like an old man.

Maybe you should try asking for a water temp sender instead, all that thermo talk is enough to make someone's head spin

The water temperature sender is the one that goes to the gauge in the cluster. The sender is in the rear housing.

Because it's not the temp sender, that i need,

Its the thermo sensor.

Bah, silly me! These cars get freakier by the day sometime https://www.nopistons.com/forums/pub...#>/biggrin.png

well i called mazdatrix, can you belive they want $40.00

For this damd thin, someone mentioned pepboys,

think the might be any cheaper?

do it right the 1st time. don't get some crap from someonwhere else, just go spend the $40.00

The sensor that Pep Boys sells is about $30. It works well.

This dam overheating problem has allready cost me,

$200.00 for fan clutch, $150.00 for Rad, $75.00 for waterpump

$12.00 for T-stat,$75.00 for Towing, Now I break this stupid

sensor, $40.00 For crying out loud Its not that im trying

to be cheap, Its Im going Broke!

If you really don't want to buy one new then I have a 2 year old sensor I could send you for $10 shipped.

You got it. Give me your address and I'll get a Money Order

in the mail. Tommorow. Thank You

I'll send you a PM with the information.

Cool thank you

You're welcome.

Well I got the sensor in the mail today.

Installed it now everything is back to normal.

I would like to thank everyone for all the help and info.

Especially 13BAce, thank you very much.

Now you know that it's an important sensor. https://www.nopistons.com/forums/pub...DIR#>/wink.png
