Well I hope that they did not put 150PSI into the cooling system as that would just about blow the radiator apart, coolant temp sensors should not be sealed with anything especially if they are a single wire sensor as they must earth through the block to work, they should be a tapered thread or have a alloy washer to male the seal.
