Hi, The other day I noticed that the cooling reservoir of my DeLorean was empty, since I was a long way from home I added 2 liters (0.5 gallons?) of water which filled the coolant reservoir to the required level. Today I was driving in a traffic jam and suddenly the temp meter went to 104C (which is the last white line on the scale) and that scared me a bit. When I caught speed again the temp meter dropped to a more regular level. On the way back there was no traffic jam so I could drive home without any temp problems. I now wonder if the balance coolant/water might be off in such a way that it doesn't optimally cool the engine anymore. My 2 questions in this light are: Is it normal for the engine to heat up this much in warm weather (88F) when driving slowly for aprox. 30 minutes due to e.g. a trafic jam? Is it advisable to drain the entire 3 gallons of coolant fluid and replace it with fresh fluid, and if so how do I go about draining it? If this (second question) is described in the tech. manuals then just tell me, I'll be getting all my manuals next week and I can look it up myself. I'm just a bit impatient. Thanks, Sacha #17115 P.S. AFAIK there is no Fanzilla or other similar system installed in my DeLorean
