Good Day! The temperature light on my 1998 1500CT does not work plus I think my bike is running a little hot as the fan comes on from time to time even when I'm riding.Yes its hot here in Costa Rica, but I still think this is not normal. I'm be in the US next week and was planning on purchasing a temperature guage and thermostat. I'm look for suggestion on any other parts I should have on hand before I start this job.

How did you determine the temp light doesn't work?  I have had my 97 STD for over 16 years here in FL and they get hot in the summer. I have never seen the temp light come on.

Don't they come on for a few seconds when first started ? If Tuanis isn't doing that maybe his bulb is burned out. My fan comes on occasionally when riding in traffic. The light isn't supposed to come on when it does this. It should only come on when it gets too hot.

No, they don't, not on a standard or tourer anyway.  Maybe on the IS I dont know.

It sounds like your bike is normal. But if you really want to change the stat, be sure to get the special gasket for it.

Ok! I read in Clymer manual that the oil and temperature should come on when the ignition in before the motor is started.

What does that Clymer dude know.  My temp light has never come on and the bike was almost new when I bought it.  Now I have two bikes that were born as standards and neither temp light comes on at ignition.  I guess both mine are burnt out uglystupid2 crazy2

I checked the Clymer manual. It's very ambiguous the way it's written but it does not say the temp light should come on. It says to make sure it's operating properly but then it never says what proper operation is.

In the HONDA manual it is more clear. "Turn the ignition switch ON.  The side stand indicator and oil pressure indicator should come on".   It says to check for problems if the the temp light comes on with the ignition.

Yes, the temp light comes on for about a second when the key is turned on, regardless  if engine is started.

This is a shot from when I changed the meter lights to LED. You can see that the spot where where the temp light resides is all dark.

'98 Tourer.  Overtemp light does not come on at startup.  Mine flickers some when the water temperature gauge is reading 225* or so, which it does when stopped at a light after a freeway ride during the dead of summer (110*+ in the shade, roadways are considerably warmer)

They're supposed to - as a system check.

If not, the temp light module is faulty.

Just the opposite.  The Honda manual says if the coolant temp indicator comes on with the ignition its a problem. pp 19-7  Only the sidestand and oil pressure lights should come on with the ignition

My I/S's temp light does. My '99 Tourer's doesn't at present...faulty temp indicator unit.

Before you waste your time and money do a POLL see how many people with Standard or Tourer bikes confirm after turning on the key and checking (not by memory because they think it was on) that the coolant temp indicator is on with the ignition. 

I think nothing is wrong with your Tourer's indicator unit.

Which version of the Manual are you reading from?

As remarked earlier, mine's the 1997-2001 version...date of issue: Dec. 1998.

Page 19-11 deals specifically with the Coolant Temperature Indicator.

Mine is the 1997 manual released in 1996.  Maybe after a certain date, when they did make some changes to the coolant system then the lights come on.  Would be interesting to see some later model owners pipe up and confirm that theirs are supposed to come on with the ignition.  If that's the case Id bet money yours falls into the older category where the light doesn't come on.  Many changes to the standard Valkyrie were made around 2000-2001

01 Standard. Light does NOT come on with key. Only when overheated. My year manual confirms this.  2000--up standards/tourers should be the same.

I know the I-state is different, and I suspect the 97...that had a coolant module thingy...is different. I don't know about the 98/99.

Well then I suppose that confirms that 97 and 2000-2003 stay OFF.  Mine is a 97 (both) and neither come on, and the 97 year specific manual says they dont come on.  Would be strange for just the 98 and 99 to be different but we'll see if a 98 and/or 99 owner pipes up.

99 tourer mine does not come on with key, only flickers once in a while, so I know it works. Does not over heat, just flickers sometimes. Fan comes on and works fine also.

Ok.... thanks 99, that makes 99.99% sure no standard or tourer should have the temp light on with ignition.

The Coolant Temp Indicator comes on for the IS with the ignition, not for the standard or tourer period, done.
