Water temp light..normal?
« on: 28 November 2007, 23:07 »
Hi,

I noticed this week when my engine temp reaches near the 114 mark - the coolant light comes on (water temp too high warning?) the fan comes on and the light goes out. I checked and coolant level is ok.  :huh:

I would have asummed this was normal but it never used to happen before, only used to come on when the coolant was low?

Apologies in advance for what may be an eternally asked question!

Thanks in advance,

Goops

My valver went up to 116 in summer, in traffic but the light never came on. What was your water temp guage reading at that time?

Water temp gauge was sitting near halfway?

Mine is usually about 100 on a normal drive and can get up to 110 through town. Is that normal? How do you know?

My query is regarding the coolant warning light....is it normal for it to come on at halfway mark on water temp gauge?  :huh:

"Normal" engine oil working temp as far as i know is between 100 and 120....

Sorry not sure but would check the resevoir if it was me. I have been wondering about my engine temp lately and think it best to do a flush and replace with new coolant for the winter. The only thing i know about coolant is not to mix different types together as can cause problems. That's still not answered your question though.

Coolant level is fine, flush done not long ago (doubt its dirty sensor), got G12 coolant with water only!
Look forward to all your comments, otherwise il have the NFS....nervous fidgety syndrome of checking whether the red light has pinged or not! :laugh:

Just a thought.. What if your thermostat isn't kicking in when it should do? Probably shouldn't worry till you get steam comming out of your engine.

Normal oil running temp is safe up to something like 140 on the MFA according to the handbook. Valvers run hotter too. As for the water temp light, if oil temp is ok and the gauge is not going to the red and the level is not below minimum then you should be ok. If it's the thermostat sticking then the water temp would go higher than it usually does but not to the red line. Half way is normal. There's a way of checking if it's your thermostat's ok by waiting for it to get to temp and then checking your bottom hose to see if that's warm because if it's up to temp but bottom hose is cool then thermostat is probably sticking, but do a search just to confirm if that's correct. 

My water light flickers on on my Rallye sometimes but I find a quick slap on the top of the dash stops it. :rolleyes:
......now officially dubless.
