How To Find A Coolant Leak Without Visible Leaks

IVE BEEN LOOKING AT VIDEOS FOR DAYS AND DAYS, AND THIS IS THE MOST HELPFUL ONE BY FAR!

You didn’t help.

Taikuu, I have a neighbor has a f-150 and we can't find the leak, we will sure take a look at the oil, tho there is never an over full on the stick, quite the opposite, have to add oil freq.

I have a problem with my 2017 Ford mustang v6.

Hi, my mazda 3 coolant reservior is getting empty in 15 mins after i fill n run if for 15 mins. It’s headache 🤕

What is the solution to this problem? Will this be Miss diagnosed as a blown motor?

simple just dont buy a Ford, especially a diesel engine Ford, biggest load of crap, so many mechanics have also said ford diesel engines are bad

Im having this issue with my 2105 Lincoln mkz. But i noticed it happens when i drive to work. I work 25 miles away from my home.
In the morning its on the max line and by the end of the day is below the min line 😢

Great video. I am having same issue with my wife’s 2013 Buick enclave, she came back from work the other day, fan continued to run after the car was turned off. Check the coolant and it was bone dry. Car is having overheating issues now as well. Of course this happened at 4 pm on a Friday 🤯

noticed i was losing coolant after my timing belt was replaced, no leaks.. ive read that it's just the coolant settling in the system. should I be worried? thxx

So the Toyota dealer messed up my radiator & put in a new one, but now the coolant in the reservoir is disappearing! Help!!!

I would add one more test to the oil dipstick, a smell test, if oil smells sweet...problem...

Thx for the video....

I knew about the milky oil item, so that's what I of course checked as my car seems to loose coolant without visible leaks. Yet that isn't the issue, the oil is black. Still a mystery what causes the coolant loss....

I'm having same problem on my 06 freightliner in my case I don't see the leak I do see steam and smell it only after the temperature gets very high I lose lot more going up a hill
I'm now going to a freightliner in Valley,AL tomorrow

Every 700 miles, the coolant in my 2015 Fusion Hybrid drops from MAX to MIN. I add coolant. The dealership pressure-tested it, saying it is holding pressure. No leaks underneath. The oil looks fine. I am baffled. What is the problem, or perhaps when cars age some coolant loss is normal? 49000 miles.

Pretty sure this is my escapes problem. Is the fix going to cost me an arm and a leg?

Do you think those "stop leak" coolant additives could plug up a coolant leak into the crankcase?

It went out your exhaust pipe because your head gasket is blown.

A really great test is to take a few drops of oil and put it on a piece of aluminum foil then put a lighter under the foil to heat it. If there is coolant in the oil it will make an unmistakable sizzle. Pure oil will just smoke but not sizzle.
It’s also an easy way I will test a used car during an Inspection for a potential head gasket leak. After test driving the car and getting the exhaust manifold hot, drip a little from the dipstick onto the exhaust manifold to see if it sizzles.

I have a 2013 ford explorer with the 3.5L and has been loosing coolant. I dont see any visibly leak and i just checked the dipstick and its normal ( level and color). What else should i check? Im getting tired of buying coolant constantly.

How weird. I'm literally coming to my computer to look up a part for the cooling system leak with no visual signs. 2014 s550 coolant leak that is a very slow leak into the washer reservoir through the washer reservoir heater.

Thanks Mike as always great info! Hope you and the family have a great 4th of July

Hey Mike. I thought for sure you were going after an intake manifold internal leak. Never thought of the internal water pump. I thought engineers were supposed to be smart. :( lol. Thanks again for the tip Mike.

When you have a slow coolant leak as you describe what would you expect your oil pressure to be at higher or lower than normal. That could also help you diagnose this issue. Thanks for the great tip.

I have the same problem in a 4 runner 99 but this truck have a timing belt no chain,I don't know where the coolant is going.water pump is new, timing belt is new, the problem start after replacing both head gaskets.

Nice Mike. Usually when we see this we think head gasket.

Today's engineering just boggles my mind sometimes. New ways to introduce coolant where it shouldn't go! 🤣 The stuff I see regularly is normally much older than this, so good to know what's in store for me in the coming years. Thanks for the heads-up, Mike! 👍

👍 thanks Mike. always enjoy everything you do.

I’ve got disappearing coolant on my 04 Nissan Titan and see weep marks on the plastic end caps bonded to the ends of the metal middle portion of the radiator. Oil is clean, so time for a new radiator.

👍👍👍

truly a moronic design. kinda like puting a condom machine in the delivery ward

Great tip and info!

👉I GAVE A CUSTOMER A $3200 QUOTE ON HIS FORD 3.5L WATER PUMP AND HE WAS SHOCKED😳

Not as milky as i'm use to seeing with head gasket, cracked head leaks. Is it just not leaking enough or is there another reason for lack of a more white milky oil ?

great tip

More than likely put inside the engine for packaging the engine in tight engine compartments of different platforms. Should really have designed an external, electrically driven, water pump like the euros use, AKA: Break My Wallet.

Have a great July 4th weekend, Mike!

My old 06 Nissan Frontier 4.0L hasn't had that problem, but then I replaced the water pump when I replaced the chains, tensioners and guides. Well, just another item to be replaced when doing the above work. Otherwise, it's the second time in teardown the pump will get replaced.

Good info as always Mike. Now that cars are designed by bean counters I wonder what the car companies have the engineers doing. 🤔

IDK if it's all Ford 3.5L but don't they have an external weep hole for the water pump?

Thanks for the video

Nissan V6 engines are the other common engine with a timing chain driven water pump.

Engine oil analysis works great. You can also heat up a pan to 250 f and drip a few drops of oil onto pan. You can then watch water boil out of oil if present.

uv die is one way i find leaks like this

What do you call KNOWLEDGEABLE and SUBSTANTIAL the answer is

Great information 👍 👌 👏 thank you very much for sharing what you know with us. Take care and have a great day

Pure crap that the automotive engineers are designing engines these days where a water pump is installed inside engine design - but we all know they want you to bring your vehicle back for repair instead of you doing the repair yourself 🤨
