  1. Hi, I hope someone can help as I am at the end of my tether with this problem. I had an engine rebuild a few years back when a weak piston decoded to go for a trip through my engine block. Anyway all fixed eventually and off we go again. Then, a few years later, I have a serious overheating problem. If I leave the car running but not moving all is well. Fans kick in and car keeps its temp. However, when I am driving it, it will randomly (seemingly) suddenly - and I mean suddenly - overheat. The gauge pegs right and I lose my coolant if I don’t pull over. If I stop and let it cool down and restart things are fine again for a while then boom, it goes again. I have had the radiator restored and checked, Water pump checked, thermostat replaced. I am out of ideas, as are the dealer mechanics here in Seattle. Could it be turbo cooling issue? Anything else to check? Thanks in advance, Stuart
  2. Hi, I hope someone can steer me in the right direction. I have 2002 Esprit V8 that let a piston loose through the block a few years back. Engine was rebuilt and all was well, but then it started suddenly overheating. If you leave the car running it will happily sit at temp all day and kick the fans in and out as it should. However when I drive it it will (seemingly randomly) suddenly overheat. I mean the temp gauge pegs to the right in one fast movement. If I don't stop immediately the car will loose all its coolant - So it is not a gauge issue. If I stop the car and wait ten minutes and restart it everything is good again until another random spike. radiator has been inspected, restored, and refitted, Thermostat has been swapped out, Water pump also checked and given OK. I do not know what to try next - Any ideas? Could it be a turbo cooling issue somehow??? At my wits end - Two mechanics familiar with these cars also are stumped. Thanks in advance, Stuart
