Blown Headgasket?
I have an '01 DHS with 125k miles.
I had a misfire a year ago and had to replace the Cat. This week the service engine light appeared, and I took it into the shop. My tech said the Cat had been ruined again and he replaced it under warranty. I wondered what would have ruined the cat. The plugs and the front coil pack were replaced after the misfire, so I thought it might be the rear coil pack that's causing me trouble. The tech said it could be that, or the headgasket might have gone. He did a coolant pressure check and it was OK, but that we can't be sure until we do a leak down or test the coolant. Right now it's exhibiting most of the signs of head gasket failure: If started cold with the coolant reservoir cap removed, the coolant will flow out from the top. I have occasional rough starts and stalls. The heater only blows hot at temps > 80. I just ruined a brand new cat in less than 10,000 miles. I get an occasional "coolant level low" message when the coolant level is full. the temperature gauge sometimes is a little high. But thus far I have not overheated, I have not seen any white smoke from the exhaust, etc. To be sure I'll have a radiator shop test the coolant on Monday. If it isn't the head gasket, what could possibly be causing all this mayhem? Thanks |
sensors come to mind.
pull the codes and list by history / current.

hi stomper,
C1287 - Steering Sensor Rate Malfunction -- history B1586 Mirror Horiz. Pos Sensor-Out of Range/Open history U1064 - Loss of Communications with DIM -- history P0463 - Fuel Level Sensor Circuit High Voltage history hope that helps. |
