Bajaj Pulsar 200 NS is a liquid cooled engine based high performance motorcycle. The engine generates huge amount of power from a very tiny power plant, 200cc but 23ps. This means a lot of heat and the engine relays on a radiator based liquid cooling system to cool itself.
Heart of this system is radiator and blood of the system is the coolant or liquid which circulates through the channels made just outside of the cylinder wall to absorb the heat and comes back to radiator to cool down and repeat the cycle over and over again to keep the engine cool and at optimum operational temperature.
How often does the Coolant or radiator fluid of Bajaj Pulsar 200 NS needs to be changed ?
Here at NexGenBikes.com, we always suggest users to refer to their owners manual. As that is the best possible place to obtain more information about your bike.
As per the manual, Bajaj recommends to replace the coolant at every 30,000 kms or 2 years. However we have observed it would be too long since with our bikes, data what we have collected, points that the stock coolant starts to get concentrated by 10k to 12k kms and within 15k kms, it went below the min level marker.
So, first time, with stock coolant, we suggest you do it by 12k kms or 1 year. Starting of summer, would be a nice time to get your ride fresh coolant. The new one, if its from better brand, you may pull it for 20k or even 25k kms but stick with the 1 year drain interval.
Cooler engine helps in many ways,
- A cooler engine will reduce its wear and tear
- Less wear and tear means more engine life
- Ride quality would also increase in summer time as the bike will feel a lot smooth
- Over heated engine will result in reduce of performance.
How much coolant is required on Pulsar NS 200 engine ?
As you may see, as per the manual, you would require 1L of coolant.
Which coolant or radiator fluid to be used with Bajaj Pulsar 200NS ??
Manual says Motul Moto Cool expert or Castrol Radicool, we agree with the choice of Motul.
Be it Motul or anything else, all comes with 1L pack. One point that Motul India should note, it is pretty hard to obtain the coolant since most of the dealer stocks engine oil not the coolant (At-least that is what we faced here in Kolkata), translating into higher price (No bargain allowed).
Rs. 425/- for 1L pack.
How to drain and replace the coolant in Pulsar NS200 ??
We have wrote about the design issues of 200NS in our previous article of Tappet adjustment, as serviceability wise, design of this bike posses a lot of challenge and this task is no different.
Removal of the Tank shell
First task to access the coolant reserver and radiator cap is to remove the tank shell. Once the tank shell is removed, you now can access the radiator and reserver caps. Remove them.
Drain the coolant from engine / radiator
Next in line is to remove the engine drain bolt for coolant. Located just beside the engine oil filter. Mind you, position of this will make it hard to collect the draining coolant, so do it while keeping it in mind, it will spill into to the ground.
Drain the coolant from coolant reserver
Next is to draining the reserver, which you may do by removing the connector pipe located right under the reserver.
Refilling the coolant
Once you have finished draining the coolant, its time to reattach the coolant drain bolt into engine and connector pipe into the reserver. After which you can now refill the reserver and the radiator using a funnel if you prefer.
Once you have filled up both reserver and the radiator, seal the caps and you are done. Good for another year or 20k to 25k kms !!
Points to Note
- Do not open the reserver caps with hot engine. Always perform the process in cold engine condition.
- You can get the work done from server center or from any good mechanic, but design wise be careful with the floor / ground since coolant will spill no matter how careful you be.
- Coolant is a harmful chemical liquid so keep it out from direct physical contact (hand, skin, eyes) contact and from your digestive system (don’t drink it..)
