Coolant sensor in head (range)
Does anyone know the OHM range of the coolant sensor in the head of a 93? I am doing a LS swap and I do not want to machine the hole in the LS to accommodate the coolant sensor from the LT-1. Thanks for any help you can offer.

I'm not 100% sure on the LT-1 sensors but being that it's just a thermistor I'm willing to bet that the LT-1 and LS sensors will have the same ohm value at the same temp. I know for a fact that a 4.3L S10 temp sensor matches an LS sensor exactly. They just have different threads. But if I'm wrong and they are different, do NOT cut threads in the cylinder head for the LT-1 sensor. Every time I see pictures of people doing this it makes me cringe. Just drill and tap the water pump housing.

I know the ECTs on my escalade and 84 ohm out almost identical at ambient and reported 212 degrees. I'm pretty sure all GM 2 wire sensors are pretty standard. Hell, all sensors are probably pretty standard.
