My 914 overheats on the highway. I had concerns about the air flap, but I think the thermostat has broken and it stays in the open position. I thought something might be clogging the fan but it looks clear. I wonder about the heater air hose that goes over the motor. It could be blocking some air possibly. I may try to tie it out of the way. After exiting the highway and stopping at a stopsign the idle was extremely low, I was surprised it was still running. I turned the engine off for a while and it ran better after it cooled down. Any ideas would be appreciated.

Location?
Ambient temperature? Speed driven, what gear, what engine RPMs? 20 minutes total or 20 minutes at highway speed & load before temp went up? Are air injection tubes capped off after smog pump removal? Any pinging / detonation sounds under load? Do you know what oil temp sensor part number is being used with this gauge? All cooling tin and engine seals in place? Any big holes due to missing J pipes? AC added with hacked up engine shelf and tin on passenger side leaking in hot air? Going to need more information . . . Do you have access to boreoscope to inspect inside tin? |

QUOTE(Superhawk996 @ Jun 6 2022, 01:12 AM)  Location? Arkansas Ambient temperature? 80f Speed driven, what gear, what engine RPMs? 5th 75mph 20 minutes total or 20 minutes at highway speed & load before temp went up? 20 min highway speed. Are air injection tubes capped off after smog pump removal? Wrapped it with electrical tape, where the hose connected. Any pinging / detonation sounds under load? Didn't hear any pinging. Do you know what oil temp sensor part number is being used with this gauge? No. All cooling tin and engine seals in place? Any big holes due to missing J pipes? As far as I know everything is intact. AC added with hacked up engine shelf and tin on passenger side leaking in hot air? No AC added. No AC at all. Going to need more information . . . Do you have access to boreoscope to inspect inside tin? I don't have a borescope yet. |
