Hello everyone

Im from egypt , bought my felly at jan 2020 its a 1.3 mpi glx with ac and 120.000 km 

My only issue with it that it overheats when the ac is on when its off it cools down again

I bought it with no thermostat and the fan switch works at 68 so basically with no ac just holds 70 

The steps that i took to solve this problem were

1 changed cylinder head

2 changed radiator and reservoir cab

3 drained old coolant and got fresh one

I will be very thankful for your time and effort trying to help me

In order to have a good cooling, the cooling system has to be in perfect condition.

In your case that means:

• thermostat for tropical countries (87-82 C)
• bigger radiator for Felicia with AC
• radiator fan thermo-switch for tropical countries (87 C)
• coolant according to factory specifications
• sealed cooling system (no leaks)
• no debris inside cooling system

Let's not forget also that the weather changed dramatically during summer. Felicia was designed in 1994 when temperatures were at least 5 C lower than today.

Thank you ricardo for your time

So you are saying that i need a thermostat

And will the 1.6 radiator work for me?

Yes!

 

Please note that a thermostat does more that just "stop water going to the radiator when the engine is cold", it also controls the coolant flow when the engine is hot, and perverse as this sounds removing the thermostat doesn't always give you more cooling although it will probably give you a longer/slower warmup.

The way i solved my overheating felly was.
Removed thermostat,
Replaced thermoswitch with 85c one.
Cleaned the cooling system to THE UTMOST EXTENT.
But with ac the thing will spike up in temperature.
As skoda DID not bother to fit bigger rad but rather choose to install a higher speed fan on the 1.3 ac models

It is your conclusion. I don't know what thermostat you have now. Moreover, I gave you a list of possible reasons excluding things you MIGHT have solved.

Again, you didn't provide enough information. I don't know what radiator you have now on the car. Remember we don't know your car while you have full access to it.

If the car had AC from factory, the radiator is already bigger. If the AC was retrofitted, you need the radiator for Felicia 1.3 with AC.

Actually they did.

Thank you again recardo fo your time and attention

The radiator im using is a crappy chinese one that has thin pipes like modern cars sorry i dont know the branding or part numbers cuz it was in a blank cardboard box

Yes the ac of the car is from factory i think the previous owner had a failing head gasket so he changed the radiator to a crappy one as well cuz when i changed the cylinder head i found 2 gaskets on top of each other

I bought a used nissens radiator for 1.6 models is it better?

Now i get it thanks alot ken i will install a new one today

I don't know if you can squeeze it in. Remember that all radiators have some sort of plastic shroud (frame) that guides the air better through radiator. Without it the cooling efficiency will be reduced.

You mean this plastic shroud?

I was thinking to replace it with the old one to fit the hoses in the right places

so mine that has both power steering and ac and is in a warm climate is f@!@ked

this is a 1.6 rad.
you would need to make an adapter for the expansion tank line to make it fit as well as relocate a wiring and tubing

Concentrate in buying a PROPER radiator for Felicia with AC.

Part number is 6U0121251C.

Better clean the old one with a cooltant flush especially if off the car rather than buy true chinesium

The old radiator is not for engines with AC. Flushing it is not the solution.

As for the China radiator, each to his own pockets. I offered him both alternatives.

Does it support shipping to egypt?

I think now you have enough information to DO something.

I bought a new thermostat and tomorrow i will install it and try to order the new radiator and i think i will buy a new fan too

No, that's a header (or footer) tank.

 

There is no coolant flow through a shroud. It's just a screen that flows all air that flows over the radiator fins through the fan. This web page https://wizardcooling.com/fan-shroud-selection-chart/ illustrates the sort of things we mean. (Ricardo, this is purely to explain the term, not to show a Felicia part.)

No they didn't. 

Only difference between AC and non-AC version are mountings for fan - because 1.3 AC has 1.6 radiator fan, which has shroud covering whole rad's area. 

 

Chinese radiators have mounting points for both variants, but I've read reports, that they are problematic with AC cars because of lower cooling fins density.

 

If sourcing of original radiator is problematic, I'd consider rebuild to larger radiator from different car. Ideally 1.9D Felicia, which was used in 1.6 with AC

 

Btw, does radiator run when AC is running?

And what was used on the 1.9D with ac??
Also dont use chinese cooling parts especially in a car KNOWN to have very slim margins for its cooling capacity.
So they just installed a 1.6 fan with shroud for 1.3AC

GOD DAMN I LOVE SKODA innovative solutions always prevail

Nothing, AC wasn't available for 1.9D from factory. Only aftermarket sets exist, but they're rare.

 

I think that outlet hose is reason why 1.3 didn't have larger radiator. Even with small 1.3 rad it must've been rerouted to clear compressor. Larger radiator was available - that variant for warm climates, which is basically 1.6 rad with 1.3 header/fioter.

My car has AC from factory. It has bigger radiator, same fan as non AC cars. It is standard for countries with tropical climate.

Do you have some pictures? If there is some tropical AC radiator, it's not 6U0121251C, which has same dimensions as non-ac. This is how it looks like with fan installed. In 1.6, about 10cm of radiator are not covered.

Update for you guys

Finally i had some time to squeeze the 1.6 radiator and indeed it is 10 cm wider

The fan switch is squished between the radiator and the alternator but it works

I did fill the system with cooland and noticed it took ages to warm up but the fan didn't kik in so i took off the reservoir cap and holy smokes it had alot of pressure and alot of coolant came out so i figured i got air in the system so i started to bleed it from air toped it off to the mark the fan kicks in alright and stops for 2 to 3 mins but didn't try it on the road or with ac maybe tomorrow we will see the results and post an update
