Funny you post this. Earlier this week I had a hemi truck come in, complaining of a coolant leak and overheating. The cooling system had no coolant in it, so I filled it up and pressurized it to 15 psi. Inspected for leaks, no leaks. Ran the engine with the pressure tester still attached and the pressure shot up to 30 psi in less than a couple minutes... I took the pressure tester off and ran the engine and got bubbles coming out every 3-5 seconds. I recommend headgaskets and inspecting the cylinder heads. Customer declines and gets vehicle towed elsewhere. Advisor calls our shop and says we are stupid and it just needs a radiator cap....now I’ll be honest I was dumb and didn’t check the cap, but from what I saw there was a bigger issue than that. Oh well this looks like a good tool to add to the arsenal
Your diagnostic was surely right... I saw a bunch of poeple just changing the radiator cap.... They are the same poeple who just change the gaz cap when they saw evap leak....
It's always the tech that sells the cheapest repair is the one that is right. What you might not have heard is what happened a day later when it overheated again.
an overpressurizing radiator cap does not explain loss of fluid and bubbles. Granted, a cap is a cheap test before committing to big bucks, if they have the time to play around and/or get stuck.
Been using one of those for a long time. They work pretty well even on diesels. However one note of caution a vehicle with a blow water cooled EGR will also give a positive reading. So it’s important to still do a leak down test prior to yanking the head.
Well, the liquid on my Gen 3 Prius turns greenish. Changed head gasket, water pump, thermostat, EGR (valve & cooler) - all parts new Toyota original. Still greenish liquid. The car runs fine, no codes. But it bugs me a lot. On the 2nd car with exact same engine (Prius v 2012) it stays blue no matter what. What it could be?
Don't forget your screw driver on top of your box, lol but anyway that tester is just like my old Bluepoint tester I have had for a long time and yes the old breath test was priceless.Great video FRM and as always keep them coming.PEACE
Great video thanks brother. I can't believe you're telling me that the old way is over. I can't just take the radiator cap off and get it blown out at me and look for bubbling. I can't even look at the exhaust and determine by the color and smell. I am not happy about this dang it. Sorry about the rant but I am to old school. Keep up the great work see you in the next video thanks again brother. I know all the new stuff and myself don't get along very well.
Great video Sir. I did the test today on my Prius 2010 with a single chamber and it just a little bit turned green. I also noticed the brand-new fluid exposed to daylight will turn yellow. Is that a good indication that I have a small leak. Which product or brand would you recommend to seal it please. Thank you
good morning frm drain a little coolant out of the radiator then the test drive...and if exhaust is there it turns yellow bam! it has turned a little bit off from blue , I wont count that.. good tip about not doing it inside hope that cam actuator solenoid you had worked out
Good video and your right in what you said we had a blown oil cooler on a ford focus did that test and one of our thecs said its head gasket but i said isolate that first and flush the cooland and the test stayed blue then showeing it was the oil cooler and not a head gasket failure so like you said quick test then ingratiate great video 🖒
Flat rate master, what kind of mechanics make the most money? There are engine guys, transmission, HVAC, electrical,front end, glass, etc. etc. Are there any kind of specialty mechanics that make more than others? Also, do certain dealerships typically pay better? Like a BMW specialist vs. a Honda specialist
Nick , The issue is not if BMW pays more . It can vary. Honda have more cars on the road . So more volume of work. And also how many technician at shop , too many techs = less work .
Hit and miss isn't good enough with all the time, money, and reputation involved. We use a hand held snap on 5 gas on any car that misfires, overheats, or has a low or no hvac heat output complaint. It's as big as a dvom very reliable and accurate.
The tricky head gasket leak lol I dont like that kit i think todays engines are way to advanced ,its hit and miss I still go to my coke bottle plumbed into cooling system go for a hard drive jump out check for bubbles 5 gas tester way to much $ Great video
what a stupid thing to suck or connect some hose(like my kit has one) to the vacuum inlet(instruction says that) - what for??? Anyway, I see that bubbles go trough that blue liquid - it means any gas(air pockets or exhaust gases) goes through the blue testing liquid in any cases and no one needs to use that fucking vacuum pumps/hoses???
In The video I misspoke I meant to say CO2 not CO
I was already very worried that you were breathing out CO 😂

Great review, something to keep in mind if I get a head gasket job. Now we know how you lost your marbles! Have a great weekend, FRM!

Confirmed what we already knew about your head gasket!

You blinded me, with science.

Mike get the head gasket fixed quick. Hahaha cool tool.
Does it work with Honda blue coolant?
Hey FRM,that fluid detects CO2 [carbon dioxide] also a byproduct of combustion and respiration!
Yes I know I misspoke in the video :(
No worries man.
💨💨💨😮😊👍🏼 Thumbs up Flat Rate Master
That appears to be a better tester than single chamber testers I'm used to seeing. Just curious, does anyone here reuse the same fluid?
The tricky head gasket leak lol
I dont like that kit i think todays engines are way to advanced ,its hit and miss
I still go to my coke bottle plumbed into cooling system go for a hard drive jump out check for bubbles
5 gas tester way to much $
Great video
I use that same kit.
I have the same kit. works great. thumbs up
why can't one use this product to sample exhaust?
It detects CO2 so it will turn green instantly, and that is normal in exhaust
I could use a kit like that
"mileage may vary" lol
You're breathing out CO? Think you mean CO2 carbon dioxide brother 😉
First ;)
I think he’s blowing out methane gas 🤪
what a stupid thing to suck or connect some hose(like my kit has one) to
the vacuum inlet(instruction says that) - what for??? Anyway, I see
that bubbles go trough that blue liquid - it means any gas(air pockets
or exhaust gases) goes through the blue testing liquid in any cases and
no one needs to use that fucking vacuum pumps/hoses???
