Radiator fan taking a long time to turn on

Why did you use Engine Ice in the first place?

 

its meant for anti freeze which is normally the case in colder countries where radiator fluid runs the risk of freezing into ice.

 

your normal radiator fluid or Maxima coolaide should do just fine.

There is one motorshop that always recommend using this along with their package..I use before. After like two months, I flush them out and use normal coolant.

Okay so you guys recommend normal coolant will do?

[CSV]

try normal coolant and see what it does.

 

i recomend Maxima coolaide. not expensive. 20 bucks for 2 litres.

Hi guys, I ride a 2005 Z1000. Recently when my bike hit 45000km, I did valve clearance, timing chain & chain tensioner replacement. I also did engine oil change, spark plugs, oil filter and I flushed the radiator and decided to EngineIce.

 

After I collected the bike, the power and response was fantastic but I noticed the engine temp was higher than usual. Before I did my service, the radiator fan would come on at 100 degrees celsius and the highest I ever saw was 103 degrees celsius.

 

Now when I'm riding at low speed in carparks or in jams during hot weather, it goes up to 110 degrees and the fan only comes on after a prolonged time. One time during a really scorching afternoon, I was in crawling traffic at the checkpoint for a while and saw 110 degrees yet again then I decided to kill the engine and saw the temp. show a blinking 116 degrees. Shortly after I turned on the engine and it dropped to 108 degrees as the fan turned on. What could be the problem? Thanks!

 

I doubt it has anything to do with the new coolant. Go back and let them know abt the issue, it was ok before you sent for servicing. Coolant change does not affect the temp your fan cuts on.

[Hydher]

my two cents.

 

Change to water wetter and monitor the fan. Could be a faulty temp switch too.

have a check on the temp switch/relay..

use of diff type of coolant will onli determine how fast the coolant adsorb/release the heat and its boiling point of the coolant.

Things to check:

 

1. Radiator Cap - Check if the spring is wearing out.

2. Wiring - Your symptoms doesn't sound like bad wire but do check out on this lead.

3. Thermostat - Though unlikely but still a possibility.

 

One thing to share though, I run distilled water in my radiator. Coolant are actually more suited for cold climates where anti-freeze in coolant prevents the coolant from turning to ice. The chemical properties of anti-freeze actually causes oxidation and in turn, rust. Therefore, using distilled water actually runs as effectively while reducing oxidation. Distilled water is preferred over tap water as it is pure in its H2O form without other chemical properties. One advantage, it costs me $0.85/l and I change them once every 6 months.

Using pure distilled water shortens the lifespan of your waterpump significantly. The coolant also lubricates the pump, which water doesn't. So the bearings and your impellers wear out, very quickly. That's what waterwetter is for, additive to raise the boiling point of water and add lubrication for the pump. Try taking coolant and rubbing it between your fingers, you'll notice its slippery. That's what water lacks.

Ohh. Great knowledge. So you recommend waterwetter instead of Engine Ice? Where to get waterwetter?

there are 2 types of coolant generally in the market.

one is glycol based while the other is water based.

products such as engine ice, general green colour coolant bought off shelves at petrol kiosk is made of glycol based.

products like waterwetter and maxima coolaide is made of water based.

the diff between both is that glycol will lower the freezing point of coolant mixture so that it will not freeze up when winter comes (Sg will not have this issue).

common point for both is that it will prevents oxidation which is rusting to metal parts and increase the boiling point of the coolant mixture.

Heat conduction is best in solid or liquid state and worse in gas state. (primary sch science)

Race bike equip with distilled water is due to pure water have better heat conductibility compare to coolant. but bear in mind that the bike is service much more frequently than us using on road.

Glycol coolant is not advisable from competition is due to safety reason. If the coolant is spilled on the track, the slippery effect is a no no for trackies.

Race bikes use distilled water because coolant is slippery due to the additives they put in for lubricating the waterpump and seals.

 

Any leakage on track is hazardous to the riders.

coolant lubricate the pump seal and keep it from drying. most motorcycle water pump bearing is sealed from the coolant itself. no way the coolant is doing anything to the bearing.

 

pure distilled water does nothing much to prevent rust and corrosion. that the main problem.

 

main purpose of waterwetter is acting as an anti-corrosion agent and breaking the surface tension of the water so it trap less air bubble. it does very very little to increase the boiling point of the coolant.
