Something that is probably the most important thing you will have to take into consideration when you are doing everything in your power to get the V35A-FTS engine in excellent condition is that you will have to perform a coolant flush. In this article today, we are going to cover everything that you need to know in order to maintain your V35A-FTS engine coolant system in a proper condition. From the engine specifications to why you should maintain your coolant in a proper condition and how you can flush your coolant – all in this article!

What is the V35A-FTS Engine

Let us leave the engine itself, the V35A-FTS, for a moment before going into the nuts and bolts of servicing the coolant system. The V35A-FTS is Lexus’s turbo V6 high-output engine and is used in some of its luxury cars, the Lexus LS500 and Lexus LC500.

The V35A-FTS engine is the epitome of silky power, fuel economy, and refinement. The V35A-FTS engine specifications are shown in the table below:

V35A-FTS Engine Specification:

  • Displacement: 3.5 liters
  • Configuration: V6, twin-turbo
  • Maximum Horsepower: 416 hp (310 kW) @ 6,000 rpm
  • Maximum Torque: 600 Nm (443 lb-ft) @ 1,600-4,800 rpm
  • Fuel: Gasoline
  • Compression Ratio: 10.0:1
  • Turbochargers: Twin-turbo
  • Fuel System: Direct injection
  • Transmission: 10-speed automatic
  • Cooling System: Water-cooled with a liquid-to-liquid intercooler

The V35A-FTS engine is strong, but as it is a high-performance engine it requires service and maintenance at the proper time to provide its best output and performance.

Why Coolant System Maintenance is Important

Your V35A-FTS cooling system engine is what maintains your engine at its ideal temperature. Overheating your engine will cause expensive damage to your precious engine parts like pistons, valves, and the head gasket. It is thus of the greatest importance that the cooling system be in pristine operating condition – it prevents the engine from overheating and at the perfect temperature for optimal performance.

Reasons to Preserve the Cooling System

1. Prevents Overheating

The main and initial intention of the cooling system is to avert the engine from getting overheated. Low coolant level and flow can lead to the engine overheating to an extent that it becomes worthless, completely ruining it.

2. Guarantees Long Life for Engine

Maintaining your engine fresh, i.e., flush coolants, will keep your engine running years ahead by maintaining the engine at one temperature. Overheat is the most frequent cause for an engine breakdown, and for extending a long durability longer, a smooth running cooling system is the solution.

3. Improves Performance

V35A-FTS engine is powered by efficiency. Properly serviced coolant system maintains the engine in a healthy state without dullest and provides smooth power.

4. Prevents Corrosive Hazard

Antifreeze is blended with corrosion-proof and rust-proof coolants. Dirt settles down in the coolant and it becomes inefficient with time to guard the engine. Complete flushing of coolant prevents corrosive accumulation.

5. Better Gas Mileage

Cold, clean engine = better gas mileage. Overheating burns up gas mileage, and that’s money you save at the pump.

What Happens If You Don’t Maintain the Coolant System?

Failing to maintain your V35A-FTS engine coolant system current causes lots of issues. Some of the issues with low current coolant are as follows:

1. Overheating Engine

The engine overheats on low coolant or dirty coolant. Internal components, like the head gasket, are warped when an engine is overheated. This is extremely costly to replace.

2. Poor Engine Performance

Your engine will not be running as it should at its optimal operating temperature if the cooling system is not functioning properly, and that will create poor performance in the mode of power loss and slowness.

3. Overheating and Worn Components

Coolant will, in the process, also acidify itself and wear out your engine cooling system. It wears out components like the water pump, radiator, and hoses and causes leakage and system failure.

4. Reduced Engine Life

Extended overheating as a result of skipping coolant service will reduce your engine life, necessitating costly overhaul or even premature complete engine replacement.

How to Defrost the Coolant on the V35A-FTS Engine

You already know why the cooling system should be serviced; it is time to learn how to flush out the cooling fluid on the V35A-FTS engine. Coolant flushing is draining the system and topping up with fresh coolant. It is among the most important procedures that maintain the engine coolant system in good condition and must be performed from time to time.

Step-by-Step Procedure on Flushing V35A-FTS Engine Coolant

Step 1: Preparation of Tools and Materials

Make sure you have already prepared the following tools and materials:

  • New coolant (make sure it is the recommended coolant for your V35A-FTS engine)
  • Drain pan or bucket
  • Funnel
  • Socket wrench set
  • Hose or garden sprayer (optional for more extensive flushing)
  • Gloves and safety glasses

Step 2: Safety First

Before starting, the engine has to be cold. Working on a hot engine is taking a risk for burns or injury. Allow the engine to stand and cool down for at least 30 minutes if it just ran.

Step 3: Drain the Old Coolant

Locate drain plug for coolant on engine block (refer to owner’s manual). Place drain pan under plug and back the plug out to allow old coolant to drain. Drain old coolant in an approved manner as it is toxic to human beings and animals.

Step 4: Flush the System

Draining the coolant to zero, it is now time to flush out any clogging dirt or debris from the system. If your V35A-FTS engine permits, utilize a garden hose or a flush kit of coolant to pressurize water through the system. Many cars also come with an inbuilt flushing system, or employ a pre-packaged flush kit of coolant.

Step 5: Fill with New Coolant

Second, fill up the new coolant. Fill your designated V35A-FTS engine-only coolant into the radiator. Fill the radiator slowly with a funnel beginning from the top to the suggested manufacturer level. Also, don’t forget to check the coolant reservoir and fill it accordingly.

Step 6: Leak Check and Test

Turn on the engine and allow it to run for several minutes to allow coolant to circulate through the system. Inspect the radiator assembly, hoses, and water pump for any leaks. If everything appears to be in order, turn off the engine and let it cool. Double-check and fill the level of coolant if necessary.

Step 7: Drain Used Coolant

Don’t forget that old coolant must be recycled. Bring it to the recycling facility or to an auto parts store and they can take it away for you.

When to Do a Coolant Flush

For an engine V35A-FTS, in standard procedure, replace the coolant every 30,000 to 50,000 miles (or 3-5 years), depending on your conditions of use. If you don’t know if the engine is hot running, or if the coolant is dirty-colored, you will need to flush ahead of that.

Keeping your V35A-FTS cooling system in top is the secret to your engine running as economically and as efficiently as it can, for years and years to come. The most critical maintenance program is a coolant flush, which keeps your engine from overheating, rusting, or other things that keep your engine from doing its job.
