[DML] Cooling System/ Temp Guage

["ltshaneclarke" <ltshaneclarke@xxxxxxxxx>]

I had one question for everyone and then some comments.  
On the back of my water pump right below the thermostat there is a 
large bolt and a washer that has a slight leak.  I've tried torquing 
it and it still has a slight leak.  I called DMC and they told me to 
take it off and purchase a new washer at any hardware store.  Before 
I begin my project I invite all comments on size, type of metal and 
any special torquing techniques for that particular washer bolt 
configuration.
With regards to the temp guage not working on someone's D.  I had the 
same problem and ended up oveheating on the road due to a moron 
mechanic who told me he blead the cooling system and didn't.(I now 
always do it myself!)  I replaced the sender located on the passenger 
side of the engine block towards the firewall.  I then replaced the 
guage itself and it finally started working.  Another issue you might 
have is the wiring itself is bad. The replacement of the guage is not 
hard at all, and the only thing to remember when replacing the sender 
is drain the coolant system first so you don't have a huge mess.
As to the coolant, tap/distilled water debate.  I always use Prestone 
premix, which is prestone's "green" coolant premixed with distilled 
water, it's excellent.  I also throw in some red line water wetter, 
which has kept my car from getting even remotely hot in the Florida 
sun.  The biggest thing to remember with these cooling systems is to 
remember to get a good bleed, or you'll have a pretty bad day.
Love the forum!
