Cleaning the radiator - is it necessary? - Toyota Avensis, 2.0L, 2001

I often met in the press notes that people clean radiators at least once every 2 years. At the same time, driving on a diesel engine that in itself heats up a little + living in the far north never felt the need for this procedure.

Usually my car in the summer by myself, I throw a Karcher on the radiator in the front through the grill, well, that's enough, it seems clean.

I arrived to the south, the car started warming up during long climbs at any speed and at a speed of over 130 km / h. At the same time, the air conditioner began to freeze worse. Initial inspection showed nothing, the external (air conditioner) radiator was pristine. I decided to fold the main radiator slightly to the side, giving the fasteners, here I experienced a shock, all the muck from the road flew through the air conditioner radiator freely, and settled in a single impenetrable thick carpet on the surface of the main radiator and in the honeycombs.

The radiator was removed and cleaned in NipponAuto (Novorossiysk), after spraying with detergent foam for contactless car wash and long-term washing with a cracker (distance of 25 cm from the nozzle from the honeycomb), the radiator showed almost 100% purity and transparency.

Do not neglect a good high-quality cleaning of the main radiator!

also partially changed (what leaked out, refilled with a new one, 4 liters)

Here is both! I will also wave antifreeze at the same time.

it was also washed, of course, in place without removal, but basically I think it became better because the flow began to pass through both radiators normally, and not rest against the second, which contributed to the accumulation of hot air in the radiator space ...

Interceptor 15.01.21

Well, you see it washed too ?!

SuBuR 15.01.21

By the way, I noticed that the air conditioner began to work better.

I'm also going to do this procedure!

The first thing I did was give the kondishka to the officials for refilling! They said everything is fine, I also think that plus 33 - 36 degrees did their job, and he simply did not have time to cool the air much ?!

Well, since the arrow does not go to the top, it means that everything is not so scary and perhaps the air conditioner just needs to be refueled. If it runs half-charged, the compressor is very worn out.

Polar51 15.01.21

Yes, it will be necessary to plan this procedure next year! And then on this vacation, the kondisha was not very cold. And the arrow does not understand me, always in the same position) like everything is ok)

hmm, thanks =) better update. I will try, although I have not overheated even once in 5 years

SuBuR 15.01.21

yes, cream is a must. If you drain it carefully, then you can pour it back.

E-darkness 15.01.21

unknowingly, I will ask the question: do you need to drain the antifreeze at the same time? if you pull out the radiator
