I have a FWC engine that had overheating problems. I installed a ball valve to override the thermostat and it now runs much cooler (170). However, when I point my infrared thermometer at the the engine, there is still a gradient across the top of the engine. The starboard side is 160, the port side, next to the manifold is 200.
Three related questions:
1) Is this normal, or should both sides of the engine be more or less the same temperture?
2) If it isn't normal, I'm guessing some de-crudding is in order. Does the acid flush help when only antifreeze (no salt water) has been running through the engine?
3) If I should do an acid flush, How do get rid of the acid? The instructions say that after the flush, you should run the engine for 15 minutes to flush the acid out of the block. That's fine if you have an ocean of coolant, but I don't want to use 15 minutes of anti-freeze.
Thanks,
SG
