2009 Mazda 6 coolant leaks, Replacing Coolant Temp sensor Housing

[@kcharry]

Hey wassup brother, thanks for Taking the time to post this video. I have the same issue on my vehicle and couldn’t find the leak for the life of me. Thank you

[@RBTheMechanic]

Oh I see yeah it’s Common part That wears out

[@toatakeifanga2434]

Thanks for your video. Now I understand the problem of my car and my mechanic fixed it. I won't even attempt to do this job.

[@RBTheMechanic]

Yeah !!! Make sure I buy sensor also I had to order after

[@eevee_hp_tp4129]

Bro you save my day! Same problem same place same part and my engine still up and running! Great Vid

[@RBTheMechanic]

Niceee job!!! This was A tec job if u got it don’t u deserve ASE certification

[@eevee_hp_tp4129]

@@RBTheMechanic took me about 3 hours but got it done. I rather do things myself than spent 900$ on something that costs 90$

[@RBTheMechanic]

@@eevee_hp_tp4129 yup it took me good hour or more as well

[@theMysticMan31]

Hell yeah happy i found this pretty sure this is were mine is leaking from. I was pretty intimidated by all the hoses and wires but your video made quick sense of that for me. Was worried i was gonna have to take it to a shop but after i feel very confident i can do it myself. Just missing a single tool to finish. Got it over half way done though.

[@RBTheMechanic]

Cool

[@damenlee2195]

Nice, straight to the point, informative video man. Appreciate it

[@RBTheMechanic]

Welcome

[@Megatronmarc]

The same thing happened to my car, Thanks for making this video.

[@RBTheMechanic]

Welcome

[@لافي-ر1ك]

Thank you for the video. And the time you worked hard. I had the same problem with the temperature sensor and it was late in reaching me after the purchase ❤❤❤

[@RBTheMechanic]

Thanks

[@ajf4693]

Glad I found your video. Mine just broke this morning, guess it’s the gasket. Great video man👌

[@RBTheMechanic]

Yeah not so bad to do just take ur time!!! Get that sensor also if u get the same part

[@ajf4693]

@@RBTheMechanic It was actually pretty easy, though I was going to take all day. It only took me 2 hours labor plus new coolant and purging the system. Purging it take a long time.

[@RBTheMechanic]

@@ajf4693 yeah not so bad good job!!!!

[@dougtheunicorn193]

Awesome video. 252k miles and mine just failed. Looks pretty simple. Thanks for the video!!

[@RBTheMechanic]

@@dougtheunicorn193 yeah not a bad job!!

[@tylerlavely2317]

What are the two sensors that sit on top? There was a redish brown one and a black one, you mentioned something about not breaking them and you were having a hard time with the red one in the video. Mine snapped off and i have no idea what its even called to replace it

[@RBTheMechanic]

At what time frame u see them

[@louiegiltampoc8949]

Thanks for this info. I just replaced mine. Wondering the indicator seems not working properly. When i started the car this morning, indicator indicates the temperature is already in the middle although i have just started the car which should start at the bottom and rise as engine runs..

[@RBTheMechanic]

Replace the tem sensor could be faulty

[@louiegiltampoc8949]

@@RBTheMechanic Thanks for your input. I will check with the mechanic. As far as i knew he only replaced the plastic block.

[@RBTheMechanic]

@@louiegiltampoc8949 yeah check with him it would had been good idea to do it while it was open

[@louiegiltampoc8949]

@@RBTheMechanic Thank you. Actually, replacement of the block (engine coolant water outlet) is done. But i noticed that when i turned on the engine in the morning, the temperature reading goes directly at the middle which is unusual as it suppose to rise as the engine rise until it reaches the mid part (normal temperature), which roughly take around 4 to 5 mins once the engine is started from cool condition. Thank you. I really appreciate your swift responses.

[@kubanczyk255]

A lot od works, good job buddy thank you all 🎉👏👏

[@RBTheMechanic]

No problem 👍

[@ASEmastermechanic]

How do you replace just the Coolant Temp sensor on this Mazda? I assume you dont have to disassemble all of that right?

[@RBTheMechanic]

Yes

[@shamaraparrah4605]

That’s exactly where I see steam and wetness coming from in my Mazda 3 it’s a 2009. My coolant reservoir is low I put coolant in the car drive and it smokes and it’s low on fluid. Also my heat goes in and out it gets hot then blows out cold air. I put my car in the shop yesterday.

[@RBTheMechanic]

Oh yeah somthing not so bad to do

[@MrDulaSlappah2133]

Can you do a video of the same car but misfires ? Or a video of what caused the housing to leak

[@RBTheMechanic]

Housing is old plastic and seal brittle and it cracks misfire I have lot of videos on honda it should be same I have Mazda also search them

[@Pinkielover]

I had a leak from here for over four years couldn't find it.. Finally it's starting to leak a little more , i still didn't fix it.. i'm gonna pressure tested in a couple days to make sure it's that the part .. Actually I'm buying the gasket .. If the housing is not cracked I'm just replacing the gasket for $3.50 They sell it But I'll buy the whole thing too separately for $75.. Because I don't feel like running to the store because I had no way to get there so I'll get everything before and whatever I don't use gets returned... The problem is I want to replace the hoses going to the heater core and I don't know the size of the hose .. Which is a pain I might just run to the junkyard and get the same hose and cut it so I could bring that sample to the parts store to get 2 new hoses .. right now my car is running at a steady 208° At Idol for couple hours . I just topped off with distilled ,, I'll flush the whole system when I'm done , I'm just putting it off because it's 115° out tomorrow And of course I'll end up doing it in a parking lot somewhere because I don't have a place of my own... Anyone have any idea of the proper pressure test pressure I should shot for,, When I do the pressure test for this particular vehicle mines a 2013 basically the same car ,, I would think a pick would be the easiest thing to use to remove that hose that you were having a problem with ,, Can you take the piggy stick it in the hose and go around it to move it off.. Anyway this should be fun definitely not looking forward to it... I'm going to put some thermal protection because there's a exhaust manifold right below those two hoses that go to the heater core I'm gonna have them wrapped in fiberglass sleeves to protect the hoses

[@RBTheMechanic]

Ummm I’m not sure u want to just replace the gasket I would replace the whole thing it get brittle also the sensor since ur in there and then it should last u years to come

[@chrsrioss_]

i did everything in this video but putting it all back together, the top bolt where one of the nuts go just broke off as i was tightening it back in, idk if to look for a new metal bracket or what

[@RBTheMechanic]

U maybe over tightened it

[@InspirationalShark-il1go]

Hey the hose you broke do you no if that hose go to the radiator

[@RBTheMechanic]

They go to heater core I believe

[@InspirationalShark-il1go]

@@RBTheMechanic I have a hose blown of inbetween top radiator hose and radiator cap I can't find we're it belongs to I'll probably have to pull everything apart like you did to find it thx

[@forestwilson1043]

please ive been looking for days what is the circle right above the coolant outlet square???

[@RBTheMechanic]

At what Time frame u see it

[@alexanderstefanxandraswedi5835]

Great job

[@BswishhhGameTime]

I have a P1299 code on my Mazda 6. It's a 2011 and it's a permanent code. Any idea on how to fix this issue??

[@RBTheMechanic]

Well is the car over heating? I would hook up scan tool to see the temperature

[@BswishhhGameTime]

@@RBTheMechanic no it's not. I did hook up scan tool

[@ralfimale1]

good job thanks for this video

[@rayanmilhuisen6132]

What happend to the part thats broken off from the housing.

[@RBTheMechanic]

Huh? It’s cracked

[@ksa78690]

Brother I have 2009 mazda6 , my temperature gauge is in c while I start my vehicle it takes time to come in mid gauge.. and wen I run the vehicle more like in highway it drops down to c again .. what’s this issue? Also pickup speed is low

[@RBTheMechanic]

Replace the thermostat it prolly stuck open

[@Tate.TopG.]

Great video

[@RBTheMechanic]

Thank u hopefully this video will help millions!!

[@Tate.TopG.]

@@RBTheMechanic it is . I am sure plenty of people will be redirected to this cuz most people like to fix their own car . Appreciate the help

[@lopeze.i.c7770]

U had to bleed it how u do it

[@RBTheMechanic]

Didn’t need to just let it run for 10-15 minutes then double check coolant

[@MrMuppet71]

What did you pump to see the leak

[@RBTheMechanic]

Coolant pressure tool was used to pump small amount of psi to the system

[@jenniferkinsella-manier8600]

Can't I squeeze a hose to get the water to circulate so I can see where mine leaks?

[@gabrielsantana2122]

Can you send a link to buy the housing and compatible sensor?

[@RBTheMechanic]

Sorry don’t have link I got it from my local part store

[@christopherbird4753]

Peace. Great job youngman. My name is Sha-King. I would like to know if this 2009 was a V6. I am having the same mystery leak in my coolant system on my 2009 mazda6 V6. Is it different on the 4 cylinder. Can you please let me know if this is a V6. Thank you so much. Again, great job

[@RBTheMechanic]

No this is 4 cylinder

[@christopherbird4753]

@RB The Mechanic peace. Where besides the dealer can I get the part for the v6. It looked like it's in the same location. The hoses go to the same place

[@RBTheMechanic]

@@christopherbird4753 autozone or pepboys can order it or u can search the part number on amazon
