However, completely blocking the air flow to the oil sump might not be a good idea. Try drilling some holes or make angled vents beneath the sump for better cooling.

It might not cause any noticeable issues but seeing that none of the new cars come with this makes me think manufacturers decided not to put one for increased cooling. This is especially true if the car is used in stop and go city traffic.
As per my understanding, there will be enough airflow even after this mod and the new 2020 Swift dzire comes with underbody protection from the factory.

Yes, there's is enough places to allow the hot air from engine bay to escape even with this cover.

However I'm talking specifically about the oil sump.
The hot engine oil is circulated and drains down to this sump when the engine is running.
Without the cover, the sump will be in contact with moving air. Therefore, lower engine oil temperature.

I tend to believe most of the manufacturers in India not including this cover on their small engine cars for a reason - less oil for lubrication and cooling. (Yes, engine oils also help cool the engine, in fact, coolant alone won't be able to cool critical moving parts of the engine, engine oil does that.)

Providing some vents on the guard will solve the issue. Most of the guards I've seen on cars come with air intake slots on them.

Just pointing out the cons of this mod, I'm sure there are positive sides too.

Speaking from my experience of being a vehicle's system and test engineer and servicing, I feel its better that the myth of "underbody panels would lead to decreased cooling" be debunked.

1. There is minimal correlation between vehicle underbody protection reducing cooling in the engine bay. The ventilation access given in the front of the vehicle allows for ambient air and radiator pressured air to circulate throughout the engine bay during driving and stationary conditions. The gaps on the side of the engine bay in the wheel arches, between the firewall and the cross member allow for air to flow through uninterrupted.

2. The majority of vehicles across the globe have in the least engine bay protection but even have the entire underbody protected with plastic trim. Automatic transmissions with their own cooling systems including oil pans don't have auxilliary cooling points or accessories because the ambient air during driving cools it down. Some vehicles even with rear chassis mounted differentials have only fins for cooling. Race cars with wet sumps that acheive much higher operating temperatures have engine guards with no auxilliary cooling vents below.

3. The reason companies like Maruti do not provide engine bay underbody protection is because of cost, not overheating due to Indian conditions. I've driven vehicles in much worse road and weather conditions than India with an engine guard and there has never been any issues with overheating. And as other users have mentioned, Maruti themselves have designed and installed the new engine guard for the new Dzire. I'm sure thermodynamic analysis would have been performed to test the overheating theory out.

4. Yes several engine guards do come with ventilation holes and channels, but that's been designed from the factory. Its best that we don't perceive that something will not work when the OEM has designed it with a specific purpose in mind.

Every user has a right to post their own views on topics, but when it comes to automotive technical recommendations, IMHO, we need to be cautious so as to not cause any damage to other people's vehicles, especially if we are unsure of the problem.

Well, I still feel direct air flow over the sump does reduce the oil temperature but agreed, it might be negligible.

Anyway, I feel like people here are overly concerned about the underbody protection, especially since it doesn't "protect" the engine from anything other than water splashes.

Since drilling holes or providing a vent on a plastic trim under the engine won't cause any damages to the vehicle, I think no harm is done.

Cheers.

Oh really? This is what a flying tiny projectile from the tyres can do to the soft and hot aluminium components underneath:

And its also helpful in avoiding kitten hunt scenes like these:

So you see, it's good at "protecting" the engine from many things, including water splashes. It won't help if you accidentally drove over a boulder, but the plastic is thick enough to prevent debris from damaging the underbody.

The engine guard has numerous small holes.

Damn, that's scary! I imagined Maruti would have done some research and figured out the under body protection was ok to skip, but obviously not, they were just being cheap!

Really stupid of Maruti and other manufacturers who skip the under body cover!

That's scary. I never thought flying projectiles from the tyre can hit there since the fenders has full cladding and the opening under the engine is small anyway. But oh boy, I was wrong.

Thank you for this, learned something today.

The part cost is 1690 in Chennai. This cover comes with holes and you need to purchase bolts/clips separately to fix it.

Re: Maruti Swift : Official Review

Painted the wheel arches with the 'rubberoid' chassis paint. 1ltr can costs 250 rupees.

It's thick but can be painted with a paint brush with moderate effort. I applied it really thick because the objective was to reduce the tire noise.

Tire noise did come down but nowhere close to
the level I was expecting. Next step is to buy another bottle and coat the whole underbody, maybe that will provide more sound insulation.

A picture of the paint can. According to the shop I've bought it from, it's widely used in workshops for underbody coating, they dilute it for spraying with a gun.

Does anyone have any further update on when the updated Swift with the Dualjet engine is coming? Thanks in advance.

Congrats on the car. The swift is a car you can't go wrong with.

I think yours is the only Lxi on the forum, so would it be possible for you to click a picture of the front passenger seat.

I just want to check if the seats are the same or different as opposed to Vxi. I know the lxi does not get adjustable headrests, but I'm more concerned about the side support.

Attached image of vxi for reference.

What kind of screws have you used to fit the underbody cover?I have procured the part,unfortunately it's lying in my car's boot for the last 1 months as the mechanics are not sure how to fix it.

You can use similar clip in the below pic to fit it and these are fender lining clips for the new swift.
