I experience this sometimes too, but as far as it doesn't make the car go off while driving, the car is fine.It's just changing gears.

Siena: And your fan operating constantly with the engine running, is not ideal.

skyfall: Can this be true for all cars? I have a 2002 Nissan Pathfinder with the VQ35DE engine. The fan is connected directly to the engine and its belt drives the AC compressor too.

The fan is thus always on even though I hear a click and notice a slight increase in speed when I turn on the AC.

hollas2jnr:
Thanks a lot Captalex. Any idea on the blinking HOLD light on the dashboard?

elviszzz: Make: Audi A6.
Model: Quattro.
Year: 1999.
Engine size: 2.8 V6 30V.
Engine output: 200 bhp.
Transmission type: 5-speed Tiptronic.
Drive configuration: AWD.
Aircon: Yes.

Aircon on:

Coolant temperature at highway speeds: Midway /75 degrees.

Aircon off:

Coolant temperature at highway speeds: 45 degrees.

Coolant / water, I dnt use coolant

Siena:

Your thermostat has been removed, as it's overcooling at highway speeds. I would strongly advice you get it replaced - if your mechanic has discarded it, then you need to buy a replacement, otherwise your engine will sludge up.

And unless you want your engine to corrode from the inside out, I would also suggest you do NOT run your engine on plain water. You need to run G12 or higher. The 2,8 30V engine in your Audi A6 Quattro is cast-iron, with light alloy cylinder heads. Running plain water, or the wrong coolant will cause a reaction between both metals, and the chances of cylinder head gasket failure is high.

Your engine output isn't 200 bhp. North American cars put out 190 bhp, with European ones producing 193.

elviszzz: Your right Sienna,thermostat was removed to allow the ac fan work directly just to avoid overheating courtesy of my mechanic. How do I use coolant to have a 50-50 mixture? Cos there is always water in my radiator,do I flush or what?

Imanuelle: Oga siena, gud evening,
Pls any idea on how much a new toyota carina E's engine costs?
Tnx

Siena:

Hello bro.

What model year, and engine size?

ngorluv: @siena thanx for this thread,its just wat I need at d moment...pls mr siena,my mazda tribute just started flashing d coolant indicator at d dash board a month ago...I av added coolant to it,yet d indicator keeps flashing.the temperature guage still stays at d middle wen d car is started...am so confused.my coleagues at work say I should get the thermostat removed dat it would stop d blinking and if not,if I venture taking d car for a long distant ride that I will end up burning the gaskette....pls wat do u think I should do...will rmoving d thermostat solve d. prloblem...pls I need ur response urgently cos am to resume work next week and start using d car after my vacation

Siena:

*Sigh*

Removing the thermostat is BAD practice, I can't understand why you guys are allowing your "mechanics" to continue destroying your cars, despite all the threads on here. Overheating is caused by other factors, removing the thermostat merely masks an inherent problem.

Removing your thermostat will NOT make your fan run constantly. The fan is controlled electronically, your thermostat is purely mechanical. Your aircon fan is controlled by the Climate Control Module, which is integral with the digital Control Panel. Your quack has bypassed this, BAD move. You need to revert your car back to factory spec, before irreversible damage occurs.



You need to drain your cooling system completely, then achieve a 50 / 50 water / coolant mix in a 5-litre bucket, before filling your cooling system with it. And I can't over stress the need to use of G12 / G12+ or the equivalent.

jum33: Hello oga siena,
I bought my primera P11 model with the thermostat removed and the engine is consuming fuel like hell.
All my effort to get mechanic to replace does nt yield fruit( becos the mechanic has to readjust the radiator fan to factory defaults after reconnecting the thermostat) my mechanics are not skilled to perform that.
Please can you recommend a good mechanic that can do that for me.My location is Lagos ,email is jummy4life2020

Siena:

I think you're confusing the thermostat, with the thermo time switch. With the thermostat, there's nothing to connect. It's purely mechanical, the thermo time switch controls the fan, so I can't see what's so difficult for your "mechanic" to revert to factory spec.

His attitude alone should tell you you're paying money to the wrong sort of person. Get your car to a Nissan dealer, who at least knows one end of a spanner from the other. I have no idea whom to recommend, as I'm not resident in Nigeria.

jum33:
Oga Siena,
So what you are saying in plain language is that,if the thermostat is fixed correctly the radiator fan will go back to default.
