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!
