Nissan N16 Sylphy

[Nadee7]

Dear All,

I need your valuable advice .Im using 2003 N16 FG10 Sylphy.Recently i noticed there is a low coolant level in coolant tank & there is a little bit coolant in Drive belts.

Recently i changed genuine belts.Heat level also normal no over heat no water drop in radiator.Only coolant tank water level going down.What is the issue ?

This is not daily happen .On & often only.

millage is KM198000 genuine .

Check the radiator cap, hoses and clamps.

It must be leaking when hot and pressure is high.

Is the expansion tank filled to the MAX  level and no higher? an overfilled extank will spill coolant as th engine warms up.

TT.

I checked water pump area & pulley also.But no visible coolant leak.But there are some coolant spreading on & often.

Can i repair water pump ? or do i need to replace if it gone ?

Looks like your water pump is on its way out. These cannot be repaired. Just replace with a genuine pump. Do not take chances or wait until the problem becomes more serious. With your cooling system it is a risk NOT worth taking.

For such a common car model why try a reconditioned water pump when you can buy a new one?Never try a reconditioned part for a water pump because this is a critical part, failure of which may result in a costly engine overhaul.  If it was your AC compressor you could have used a reconditioned part because worst that can happen is a replacement with another compressor. You should be able to get a original Nissan part (I guess the part number is 210104M525 but get it confirmed from the shop) or a genuine GMB replacement (GMB part ref: GWN73A again get it confirmed). Ask around, you should be able to get the price.

Whether there is a logo or not (anything can be printed including Rs. 5000 notes) you will have to trust the seller. If you are that paranoid go for the cheapest option and hope for the best.

Yes. If you want to save it you can collect it in a bucket and reuse. Still there will be bit of a loss which you can compensate by adding some de-ionized water.
