I use to add Coolant from Puking issues, ALOT.
I would venture to say after going to worrk at the Fire Station and staying their for a 24hr shift then driving home, my coolant temps would get as high as 202*F-208*F and upon getting home. I would add up to a full gallon of Distilled H20.
This was begining to become tedious , as no one on the forum could say for sure or not if I had headstud issues,
I had my EGR valve deleted and within the last week I had installed the Sneaky Pipe witch is a direct bolt on replacement for the OEM EGR diverter pipe. (Well, Still Knockin'on wood) With the EGR deleted through my LiveWire and the Sneaky Pipe installed, The Puking has virtually been eliminated and my coolant temps may hit 200*F under HARD acceleration , but at a cruise speed (ALOT OF HIGHWAY MILES) 250 round trip to the Station.
Anyway at a cruise speed of anywhere between 80 MPH and 90 MPH my coolant now stays at a steady 196*F. ALOT of Improvrment and ALOT less PUKING, ALL This running a 160HP Extreme Race Tune from ERIC at Innovative
PS: as for your last post on this thread prior to mine, I would add coolant when the Motor was at Normal Operating Temp. This in my opinion would verify that my Thermostat was open and all added fluids would be circulated throughout the eng. As evidence that my coolant temps alwys Dropped Considerably per my LiveWure readout. You should be able to fill the cooling system until it reads full peer the lines on your resivoir, IF NOT< You need to ask s good tech, on the ORG. or at a trustworthy repair facility, Answers like estimates "Should Always Be Free"................Good LUCK.
