Hot coolant light / Coolant fan not kicking on
 

2005 xa, 66,000 miles

My hot coolant light came on over the weekend after a couple of hours of highway driving and the getting stuck in traffic, next day happened again turned on the heat and and the light went off...but I do not want to drive with the heat on all summer!

I replaced the relay this morning ...but it is a wet rainy so the fan may not kick on anyway?

Is there a way to test the fan?

Is the fan easy to replace for a novice? looks like it should be.

Is there something I am missing to test first?

Thanks in advance!

It's probrably your thermostat.

Where is the thermostat located, it is not where I would expect it to be.

any info on how to replace?

I have just tested the fan by bypassing it to the battery...worked fine!

I have replaced the relay also today.

Is there a thermostat sensor I should be checking?

I have not replaced the Thermostat yet, before I do what other options are there?

i thought it was a sensor that turned on the fan at a certan temp. not the thermostat that opens up to add coolant. or am i thinking about a diff item?

had that problem in my honda and just wierd the fan to run wile the car was on. so it was always on.

To be honest, I dont know! I need to know though!:icon_biggrin:

As was already mentioned, it is a good chance that it's the thermostat. If not, then you may need to replace the fans.

One very useful tip for you if you live in a hot area and have to do a lot of idling.....have a coolant flush done at your local shop, and swap in NPG+ :


Will cool better than the regular coolant, has a much higher boiling point because it is waterless.

good tip with the npg! I am having some trouble finding the thermostat...usually it is on the to in american cars? Is there sensor for it or a way to test it?

that's an nice stuff it helps me a lot thanks for the info.

looks like an electrical issue, will keep posted I am taking it into the shop on Wednesday again.
