- Hello guys! How to do the CO2 test to determine if you have a blown head gasket and how to prevent such a thing from happening!? In this video I talk about the importance of maintaining antifreeze or coolant in any engine of any make and model. Consider that maintenance is always cheaper than repairs.

Very well explained, superb content thank you so much
Thank you very much for watching
Looking forward to more videos
Hello. For this car maybe not. It will be very expensive to repair this.
But I will have many more for the busso 24v
Bruno the Alfa doctor! 👏🏼
Thank you for your videos. Keep them coming.
Once a week, at least for over more year
@@alfaromeonoproblem Yes im the same. Btw i fixed my car. It was a part of wire isolation falen in the air filter box. When you load the engine this cloth tape was messing with the MAF :D
Wow, that was something
Another way to save these engines is to fit a CF2 manifolds without those precats .. In hot weather with an lpg system in ,it tends to fail the gaskets really fast , You will pass the emmisions with the main cats in if they are healthy... Im also not a fan of lpg so you going to install it at minimum place an upgraded radiator, as these engines run quite hot.. nice video btw 👍, hopefully this engine will be saved .
Thanks for this info, it will be very important for the customer to know that. And me of course. But he doesn't got the money back yet. Let's see what happens
@@alfaromeonoproblem I hope he does, unfortunately there are too many con artists disguised as mechanics out there..
Damn, hope the customer gets justice! So sad to see any Busso ruined like that 😢
I did made a video just for the court, and he won the case. But the problem now is the money back.
If you tried with the special cap with the kit tester comes would the coolant boiled and split all over the place?I think and without fan kicks at lower temperature the colour would change so you could avoid this mess.
This was an extreme example, more videos for this will be here on the channel. Thanks for the advice
Hi Bruno, great video, I have a 3.2 gt, it looses a bit of coolant but there’s no leaks or coolant smell, any idea what it might be? Head gasket?
Hello. It could be the sleeves seals to the crankcase, hope not..
I put in a cooling system a pure cooling fluid or i should dilute with water?
BTW, happy Easter if you celebrate it
Hello. Most of the hi quality ones are to be diluted in Distilled water. If not they say ready to use
You can't use just the concentrate, you need to delute it 50% with distilled water. As Bruno says, unless it is already pre-mixed in the bottle.
Also, the most common Fiat/Alfa/Lancia/Ferrari boiling problem is bad cap for the expension bottle. They fail, and can’t keep the pressure. What happens to a closed system with hot water when it looses pressure? It starts to boil. Luckily new cap is a cheap fix!
Hello. Thank you for your input. For my country failing caps is not an issue, maybe because of the climate here.
But I will be watching more carefully.
@@alfaromeonoproblem Ok heat I think is actually a bigger problem in hotter countries. But even in Sweden we can suffer from those bad caps, mine failed on a hot summer track day (Fiat Coupe 20VTurbo)
@pereldh5741 we have very few v6 here. And Ferrari I never saw one even.
On my experience on the cars I have worked on, so far, the cap is no issue. Now, on 939 series, sometimes. But only on the vent in valve, not the out one.
@@alfaromeonoproblem ok maybe a 1990’s problem, Fiat Coupe/Alfa 916/348/355 etc
@pereldh5741 yes, probably.
Se sul 3.0 v6 alfa romeo non scaldi motore e poi guidi succede subito a spaccare testata.
Ogni due anni devi assolutamente lavare dentro radiatore e sostituire liquido
Can you translate to English or Portuguese?
My friend has a 2005 BMW 520d M47 engine with 150 hp. He loses a bit of collant all the time, but there are no visible leaks. He thinks it might the the EGR cooler gasket, but there is no realy a way to confirm that unless he replaces it. I told him to check the expansion tank cap, and possible cracks in the expansion tank. The EGR is "turned off" and the DPF is removed, all by the previous owner. Not sure in what way the EGR is turned off. Blocked? Can that cause the excess pressure inside the EGR cooler and damage the gasket?
Hello. No additional pressure is created. Egr cooler is the main issue in those. And it is just awful to replace.. better to do it now before oil goes to the coolant
@@alfaromeonoproblem Thanks.
@@alfaromeonoproblem Hmm. The EGR cooler is right in front of the engine. It is a 4 cylinder, so there is plenty of room.
BTW, did you check that place from Spain? Do they have the part? If not, send me the web addresses of those places where you did find that they have them.
@DashCamSerbia I see, the early ones, ok.
I'm waiting for some answers on my local parts stores, after that I will proceed with something else
@@alfaromeonoproblem OK, but I can still buy it for you if I can and send it to you. Just send me those places.
Hey, can you help me with this. A week ago I changed the wheels to a summer set, and on one of the wheels the lug nuts where squeaking while tightening them. I screw them in by had as much as I can, an they go in no problem and without any noise. Then I put the car on the ground and tighten them with the torque wrench, but they squeel and because of the friction the torque is lower. I take the wheel off, align it again, do the same thing again but the same thing happens.
And today, at low speed in stop and go traffic, I heard the sound that at first I though it was a damaged tyre (I did hit a pot hole with that wheel, some 10-15 km before. But it turned out that all 5 lug nuts where loose. I tightened them again with regular wrench, and they are squeaking again.
WHat causes this and how can I fix it? :/
I am thinking, worn threads on the nuts, or the nub. But all 5 and all on one wheel? :I
I am going to my parents tomorrow, 25 km, most of it is highway. So I am warried untill I get there. There I will take the lug nuts off and inspect and clean the treeads at least.
I say lug nuts, but of course, I mean wheel bolts. And they also crack (sound) when tightening. Oh and I hit the pothole with the same wheel, just after I had pressure washed the car.
I think I should get new bolts, just to be safe. But the original ones are only availabe from the dealer and are not cheap at all. I found BIMECC ones, but are the M14x1,5x28 the correct ones (I have 17 and 18 inch original Alfa wheels)?
OK, I think I have fixed it. I cleaned the wheel bolts with wire brush and also the threads inside the hub. And niw the bolts no longer squeal when I tighten them.
Hello. How are you? That is because of corrosion. Clean out very well the bolt holes bit the bolts should be new, because cleaning them will remove the plating. Use anti seize to prevent that again. Lots of it
@@alfaromeonoproblem Thanks. I cleaned the bolt holes with steel brush and bolts with brass brush. Although one bolt was not very good so I had to use steel bursh n it as well. I mean, if the bolt is corroded, then the zinc plating on it is already gone anyway. I measured the lenght of the bolt threads and it is about 19 mm, not 28. And the spacing between the threads seems to be 1 mm, not 1.5, so I don't know...
About the anti-seize, in my oppinion it should never be used on the wheel bolts, as it will lubricate them. Because of that, the tightening torque will be larger than what is set on the torque werench, and because of lubrication they can loosen themselves more easily.
Hello Bruno, my car is 159 1.9 JTD. My problem is that my car is difficult to start on hills even though it is in 1st gear. Even though I press the gas all the way down, the engine stalls. Pls help me :)
Hello. Check with a testing gasket on the EGR. th-cam.com/video/CyCIdFr8WXs/w-d-xo.htmlsi=ZOeNtKAkjGFTqn9k
egr system was turned off and changed to cancelled.:(
@MutluSIMSEK77 does it as the physical blank gasket?
@@alfaromeonoproblem yes
@MutluSIMSEK77 check if it's not ruptured
