Just yesterday I made an entry where I described a problem in a traffic jam with a high coolant temperature, so - DRIVE2 is really POWER, thanks a lot to comrade Pavel (by the way, he has a very nice Niva - “BLACK RUSSIAN”) for the tip on how to check the fans yourself. Moreover, I had everything for this - OBD and the OpenDiag program installed on the phone. I check the fuses, on the advice of the NIVAvod brothers, both are intact...
Next I go to remove the radiator grill - 6 screws and 4 screws - voila, everything is ready -
The situation turns out like this - through diagnostics you can turn on the fan relay - relay1 and relay2 - I thought that relay 1 was the first fan, and relay 2 was the second fan, looking ahead - I WAS WRONG! When relay 1 started, nothing happened! When relay 2 started, the right fan (in front of the passenger who is standing) turned on, but it turned on at full blast, that is, with the sound of a “plane taking off”! I began to rack my brains - what to do... I first called the OD in Podolsk (AvtoRus) - and they are no longer the OD Lada at all since January 1... Oops! I described the problem - they say we don’t know, we need to look... I ask where the relays are - I don’t know the answer, to be honest, I’m not good at Niva... I say, well, you can drive up (purely for fun) - we’re all booked for today, for tomorrow and the day after tomorrow too It’s not a fact that there is a recording... Well, okay then! I’m calling MosNiva at 1st Botkinsky Prospect, 7A (I’ve never been, but I already like them) - by phone! I outline the situation and the answer was - the connector on the fan was rotten - 99% I give! In response to my objections - they say the car is not a year old, the mileage is only 15,000 km - they say - but look and see for yourself))) SO IT HAPPENED! F*ck, this is what I saw 20 seconds after talking with the guy from MosNiva -
I’m trying to get the connector out on my own, but I need to remove the protection and restore the connection of the wires from below... It’s cold outside, I’ve been outside for a long time, my fingers are frozen everywhere, my face is already frozen from the wind... I decide to try my luck, I call the Compass service in Podolsk, just a 5-minute drive from home - the electrician is free, hurray, I’m rushing to him! Nyvka and I find ourselves in a warm box, oh how good it is to tinker with the car in the warmth! We choose the most optimal solution in our opinion - bend the radiator a little in order to pull out the terminals from there, or either lie on the floor to remove the protection, or remove the radiators from the mounts - there are two of them... - it turned out pretty well, although it’s a bit of a shame for the radiator -
That's the way it is, guys... It's a shame about the quality of the parts, especially those responsible for engine cooling! I run to the store across the street for wires, heat shrink and electrical tape. Then a bullet to the service. Ivan (the electrician) had already prepared everything - he removed the chips and stripped the wires. Made with twists + electrical tape + heat shrink + electrical tape = zbs like)))
We check the operation of the fans using the OpenDiag program and I understand that FAN RELAY 1 - TURN ON BOTH FANS AT FIRST (LOW) SPEED, AND FAN RELAY 2 - TURN ON BOTH FANS ALREADY AT MAXIMUM SPEED (“sound of an airplane taking off”)!
As it turns out! Here I am attaching print screens -
The only negative that I noticed when working with this program is that if you turn on “relay 1”, then “relay 2” will no longer connect! You need to exit and go back into the applications - that is, reconnect! And vice versa - if you turn on “relay 2”, then “relay 1” will no longer give access... But these are trifles! Still, the program is CLASS! I recommend it to everyone! =)
Everything about everything took less than 1,000 rubles and half a day off, which I wanted to spend with my daughter, but everything that is not done is all for the better, because it is better to quickly identify and eliminate the problem than to boil early in the morning in the middle of a forest road in the cold ! =)
To summarize - CHECK THE FAN CHIPS - they are very poorly made from the factory! They need to be insulated or filled with sealant or something... Otherwise the motor can boil!
