Nothing against the guy. All respect to him. But surely, strictly from an engineering standapoint, the radiator would've been more efficient up front. Evidently, that was the case as most, if not all, transverse-engined cars nowadays have their radiators located where there's maximum airflow.

Yes. My sister's 3rd Gen Vios... And the Mirage G4 GLS I'm driving now (rented)...

Both no Aux fan for the condenser... Both cars only has 1 fan behind the radiator.

But correct me if I'm wrong, both these cars have the condenser installed in front of the radiator like a wafer, is it not? So the fan, even if there's just one, operates to cool both the condenser and the radiator at the same time.

if car owner feels natatalo ang aircon niya sa standstill noonday traffic, then he might consider adding another aux fan.

Most new cars are equipped with multi-speed cooling fans.

Agreed. Priority is to use pull type design with very good ducting/shrouding/sealing ngaun since mas efficient.

Absolutely.

But the original contention was that the new Montero was somehow "tinipid" by not including an electrically-powered aux fan, even when the necessary mounting points and other hardware were already built-in. This was addressed a few posts back as being true only when sold with the older generation engine.

As it is, it doesn't need an aux fan. It doesn't require it. But if your guts are killing you to install one, it shouldn't hurt the vehicle.

If this is a 15yr. Old or 20 yr old car. Hmm. Maybe, sige pag isipan ko pa kabitan... cheaper than replacing or cleaning parts.

If this is a young gun, all new gen, 6o7 figure priced car. Baka ireklamo ko sa casa or sold sa olx.

It can hurt. Depende na lang how you look at it.

Typical car electric fans pull 10-14 amps, not including starting amp(which is a lot since AC system cycles a lot.) Sabihin na natin additional 150watts of power from your charging system. I recalled may thread na dito regarding USB chargers and dash cam electrical load concerns? Hehe..

Not only that, if any thing happened on your 2-3year old car relating to this, sayang warranty.

It's unlikely. The 'art' of adding aux fans has been around for ages. For as long as the OEM fan was used (which is the gist of this thread), installed, and wired correctly, it should be fine.

Warranty is a different story. The owner should understand that if vehicle damage occurred as a direct result of the mod, then the dealer can refuse warranty coverage. If the mod did nothing to effect the fault, you should be able to make a claim. The burden of proof that the mod caused the fault rests solely with the dealer.
