Hi All

have a nice day 

i need ur advice in this issue 

i have felicia 97 GLX & 1300 cc with Carp.

i am installed thermostat 87 C & thermo-switch 80-90 C is suitable for Summer in Egypt 

in Egypt now it's 40 C or (95 F) 

Fan start at 94 c and stop about 88c which it's so hot starting 

need your suggestion which suitable Thermostat_ switch start before 94 c 

Keeping the fan turned on and off so that it does not run continuously

thanks for your time

The solution is to use a thermostat for tropical countries. Usually that means 10° C lower temperatures.

I recommend a thermostat that starts to open at 80° C.

 

IMPORTANT: The cooling system must be in top condition. That means:

- good radiator (clean inside, not damaged)

- fresh coolant (50% antifreeze + 50% distilled water) - NOT JUST WATER!

- clean system (no rust, no debris, no obstructions)

Thanks for your reply 

But here in egypt it's not easy to find thermostat 80c do u have another solution 

Thanks again 

Well although i know people will dissagree with me. I say NO thermostat and 85c thermoswitch.

Given its 40c out the car is not going to ever drop below 80c

Who said that?

Here in Greece we have hot cliamate too and the Skoda mechanics which had Felicia some years ego suggest 80-85C and even 75-80C thermo-switch

I have use all the scales from 70 till 90C and i have found that the 80-85 is more suitable.

 

I don't know if you can find thermostat 80C for Felicia but IF ALL the others (coolant,radiator,thermostat sensor,no leak from hose,the cap from expansion tank is proper fitting) a 88C thermostat as we have here can do the job perfectly.

Hi all thanks for reply 

I found switch 86_76 and I'll try it

But still waiting more advices

This will make your radiator turn on-off properly without the risk of overheating.

The others are OK? coolant,radiator fan,thermostat sensor,no leak from hoses,the cap from expansion tank is proper fitting etc.

 

 

Take a look at the photos in a thread of mine, i had a similar problem.

@Agalalh

You mentioned you don't want the radiator fun to run almost all the time.

A lower temperature thermo-switch will keep the fan working often.

It is not economical to use the radiator fan for lowering the coolant temperature. A lower temperature thermostat (that Skoda fitted to all cars exported to tropical countries from factory) will do a much better job.

For tropical countries that can be a last solution. The drawbacks are the radiator fan will have to serve as the regulating factor for cooling and in case the engine will not reach a stable 90° C the consumption will be slightly higher..

Thanks for your reply 

But as I said before I am not found thermostat lower than 87c in egypt so im used switche 80-90 which strat fan at 94c i think it's too much without A/C 

So do you have another solution 

Tomorrow ill try switch 88c

Totally agree consumption is slightly higher.
Even in the winter on the highway the car never drops below 75c in my case 

the lowest winter temperature in western greece though is 0-5c

switch 88c

if i may switch 88c will cause the car to run HOTTER i think its time for a coolant flush and-or a new rad.
During these hot summer days 35+c in greece the car could not keep its temperature under control on the highway with ac.
Therefore I concluded that my rad is starting to get ineffective, that might be the case for you too.

 

P.S. 1.3 engine cooling system are not renowned for their cooling capacity

Thanks for your advice really i need to change Rad

The temperature radiator fan switches have scales at 5 °C

Which thermo switch says on that is for 88C only?

Take a look some Mahle:

all of them have Switch-on point and Shut-off Point [°C]

So try without a thermostat.

And remember my previous message. There is no magical solution for a cooling system that is not in perfect condition. I have already mentioned that a good radiator is mandatory. It is the only device that cools the coolant. Bad radiator => bad cooling.

Consider a thorough coolant flush first, 

Start with garden hose,

Procced with distilled water, run the car for a couple of days (maybe add rad clean in there)

Drain it, add distilled water only, and do that for a week.

Then add coolant mix( you can try 25% 75% for a tad better themal dissipation)

I bet you are gonna recover a healthy 10-20% percent.

Some people will use coolant booster but I have NOT used them so I can NOT advise.

 

I use 80-85 fan switches and 88 thermostats in Istanbul.
Average weather 30c.

But as ricardo said the fan runs very often. (The engine is at idle while the car is stationary)

Since I use LPG, I will install an 80c thermostat.

I wonder why Egypt doesn't import thermostats from Turkey. Turkey is a huge market for car parts.

Well, quality is questionable I shall say, and getting worse than vernet parts in a hot(ter) country is a recipe for head gasket.

Maybe the Abdel Fattah Saeed Hussein Khalil el-Sisi does not allow it as the Saudi do too.

We already have a lot of products from turkey but it's dependent of the market needs and here in egypt felicia very old fashion 🤣🤣

Without thermostat which switch i have installe

In your first post you say the fan starts when the coolant is at 94°C.  How are you measuring that temperature, and where in the system are you measuring it?

 

I'm not sure about the details on a Felicia with your engine, but often the engine coolant temperature (as displayed by the gauge) is measured close to the engine head. The radiator thermoswitch is often close to where the coolant exits the radiator. It is understandable and desirable if there is a temperature difference between these positions. If there were not, your radiator would be doing a poor job.

Try first with the original one.

It would help to borrow an infrared digital thermometer (gun type) to assess the temperature before and after the radiator.
