I have one of these heat guns and I was thinking about making a video similar to this one, but you did a better job than I had in mind. The brakes are tricky, because other factors come into play. Splashing into a puddle and directional wind can throw off temperature readings. I have seen a small amount of wind throw off the left to right front brake temperatures by 20 degrees F.
Awesome video. By common sense, I've always knew that an infrared thermometer would come handy diagnosing a vehicle. At last, I found something interesting and informative using an infrared thermometer for vehicle diagnostics.
The front brakes do 70% of the breaking energy, so they should be much warmer. Your front brake were about 149° and your back breaks were about 93°, or about 0.624% the difference between the temperatures. Your breaks are very efficient in this configuration. Great video.
I do agree. I'm a mechanical engineer and the front is usually higher than the rear, the front has more load including engine weight and cabinet drive. Even with ABS and EBD brake systems, there should be a temp diff
For this model, then check engine light would have come on while the coil was unplugged as the ECU would realise the fault. Once plugged back in and on the next start up the light would have gone out. The fault code would have been stored as a Pending Code. As the fault was a once off after a few engine on/off cycles and without the code repeating the pending code can clear on its own. With a basic code reader or scanner you can also clear this code within a few seconds. Hey, thanks for the comment and I hope this explianation answers your question.
My car is front wheel drive and have problem accessing the exhaust manifold, it's in the back of the engine at the dashboard side not at the hood opening side, any other way to measure misfire?

Front brakes and the rear brakes will NEVER match. The front brakes do the majority of the braking the rear is just there to assist the front so the front will always be higher.
Hey Killa, thought i saw you working on VW 2.0 TSI. What hoses do you check for coolant? I pointed a fluke laser at what looked like the incoming and outgoing and got 115 (46 C) and 145 (62 C) which doesn't make any sense to me. My issue is the analog gauge sits at 190 (87C) but the ECU (through Torque) is reading about 222 (105 C) average . Worried because i just changed out a clogged radiator and fixed all the hoses. Pump was replaced last year with aluminum graff when i did a bunch of preventative mx, timing change , oil leaks, valve cleaning, etc., etc. THanks in advance for any suggestions.
WOw so far i have seen these temp gauges work, but the one he is showing you here is a SCA brand i believe ie: supercheap auto brand, yet i have seen no Infer red light emitting from some of them, thus must be faulty, but will check to see if these things are good compared to a touch Food grade expensive brands, also a lot of real good mutti meters have a temperature probe which you can use as well, as long as you dont mind getting you probe and hands near very hot surfaces which is why most mechanic have heat proof gloves when they are working on hot engines. :)
Hi mate, great vid! I've just put a redarc coolant temp sensor in and I need to calibrate the starting temp to match. Would I shine one of these fancy red light at the thermostat housong before the thermostat opening?

I supposed to say thank you sir for the valuable video. May Jehovah God bless you.
The front brakes take a heavier load than the back so they should be significantly hotter after use if they're the same as the front you have an issue
aaaaaarggggghhhh i looked at the laser i couldnt help it
Blinded for life now!!
I’m almost tempted to do it too...idk y 😂

very good
Thanks for the comment.

I never did the Maths but it works out pretty good. Thanks for the comment.

@@TuningLovers 'Im no engineer but even I know that. Weight transfer under breaking has a lot to do with it too.
Whatch it with that gun. I was already messed up by that thing
At what temperature is overheating happening?
Did your check engine light come on after you removed the coil wire? How hard was it to clear when you did?
For this model, then check engine light would have come on while the coil was unplugged as the ECU would realise the fault. Once plugged back in and on the next start up the light would have gone out. The fault code would have been stored as a Pending Code.

@@killawattgarage yes it did. Much appreciated!
That engine is nice . 👌

excelent video...by reading headers temps if any is running cooler than the others it may be a way to find a sparkplug or cable/coil not working ok
Spot on.

thanks great video
thanks for the comment
what is the inlet and outlet temperature when radiator fan is on ?Again if if fan is off what is the temperature ?
Each model runs at a different temperature. The inlet could be from 80'C to 110'C but the outlet will be 10-20'C lower. Thanks for the question.
@@killawattgarage thanks sir for the answer.
Good video mate
thanks mate.
Do this actually tells u the temp? Like talking wise?? My mother needs one but she is blind. Is there anything like this that could tell u the temp?
It only has a digital readout. What about this .... www.braillebookstore.com/Talking-Indoor--Outdoor-Thermometer.1. ?
Killa Watt Garage thanks for the help but she needs one to make soaps. So she will need something to dip on the water for the mix she makes.
I think you looking this

I have a Hold feature on my IR gun and what is it for? Lost my manual.
sir got a new ir thermometer, how to check accuracy of the unit?
great video ..and nice bonus ''how to fry your camera sensor by laser class 2 '' :)
Is that where the auto focus no longer works HAHA. Thanks for the comment

Do you know the opening temp of the thermostat??
@@killawattgarage vendor says 95C (203F) so that's already 13F higher than 87C (190F) as my gauge shows for center.
What does 10:1, 12:1 etc mean?
not sure about your question?
@@killawattgarage I figured it out. It's the distance to target. 10 feet, 12 feet etc.

Thanks for the comment, sorry for the delayed response your comment was sitting in a 'Likey Spam' folder.
The human eye can not see infrared.
will the car temperature sensor (coolant, engine) readings and the IR sensor readings would me different
Pointing the IR sensor at the coolant sensor should give very close values.
Very good presentation very educational thanks
