Went through a big thick mud hole while off roading yesterday, and now I'm having problems. While driving slow or stopped my temp gauge starts to shoot up. If I don't start moving or let it sit everything starts boiling. I noticed that my fan isn't turning on at all sink checked the fuses, connections, and made sure there was nothing stuck but everything looks good. Does anyone know what the problem is? Please? I have a 6 hour drive home later today.

 

Send me a message with your phone number I will call you and tell you how/ what's wrong to fix it

 

You know the fan isin't moving? If you're sure there is nothing stuck in it maybe the fan belt.

 

Fan isn't ran by a belt..

 

I'm thinking it might be a thermostat problem. Engine doesn't know it's over heating.

 

See the link below. His problem was a bad Temp sensor. Other then that here are some things to check for:

1. Flush out your radiator. The fins may be clogged with mud & debris
2. Even though you check your fuses. Check if your fan does still turn on. If not maybe it got shorted/fried
3. Check your coolant level
4. Check your water pump & verify its not leaking coolant from the weep hole

same thing happened to me when i went through a big sandy mud puddle. A bunch of dried crap got caked into center of the fan and in the shaft.

i took a big screwdriver and "helped" the fan turn...it then started running and cleaned itself out

When i got home i cleaned it out better. been working fine since.

 

Got the fan back up and running thanks to Tonka_Yellow. Appreciate all the input and how fast everyone responded.

 

So what was the problem? Inquiring minds want to know.......

 

Hose it out from the back
