[DML] Re: Otterstat Popped Out While Driving

I know I'm late to the party, but I got the Treadstone reference 
too. ;)

One thing that struck me odd about your post was that your car 
appeared to be overheating while it was being driven.  Presumably you 
were on a return trip when you overheated close to home. 

When you are rolling, the radiator should be doing its job from 
normal air flow through the radiator, provided your thermostat works, 
you have coolant that actually circulates, etc.  Especially this time 
of year, fans shouldn't really come into play much unless you've been 
standing in traffic quite a bit.

Just a thought but my guess is your fans already work OK or you will 
get your fans running and still have overheating issues.  

Idling in your driveway, your car should warm up to about the 1/4 
mark on the temp gauge and the fans should kick in very close to this 
point.  This is a good way you can monitor your fan operation without 
trying to figure it out on the road.  Also, are the fans blowing in 
the proper direction?  They should blow toward the back of the car.  
Watch your fingers!

Moving down the road or after the fans have had a chance to bring 
temps back down, the needle should ride perhaps one needle-width 
below the 1/4 mark. At least this has been a consensus of our club 
members when I polled them to figure out my problem and it matches 
what I see with my new thermostat installed.

Turned out my thermostat was stuck partially open... but a lot. My 
car warmed up some but not properly.  

If your fans DO come on and temps continue to rise, I'd guess you 
have a stuck or sticky thermostat, maybe stuck a little open but not 
enough to efficiently cool your car.

The thermostat is not too hard to replace. I recently figured out how 
to do mine. Happy to walk you through it live on the phone if you 
want the assistance.  I messed mine up a couple of times so I can do 
the whole thing in 15 minutes now!  Drop me an email if it turns out 
you'd like help.  Or maybe we can have an AZ club member give you a 

To prevent fans and thermostat from fighting one another (i.e., 
thermostat open with fans on), you will want a thermostat that is 
properly paired with your otterstat temp.
