Name that sensor

1999 lx470.



Broke the plastic clips on these sensors taking the intake manifold off. One of them is the coolant temperature sensor (the smaller one). What is the bigger one? If you take it off, coolant runs out.
Bonus points if you have a source for new clips for the wiring harness. Every piece of plastic under the good is extremely brittle.

Thanks!

The guy at AutoZone helped figure it out. The smaller one is the temperature switch or sending unit. The bigger one is the temp sensor. Don't know the difference.
