i have a new sender and i was wondering exactly where i should drill the hole for it. should it be the neck above the thermostat or somewhere else. thanks

 

If you put it on the thermostat cover, you'll have the wrong temperature readings until ~182F when the thermostat opens. I've seen them installed on the front of the water pump, which is nice since the pump can be removed for the install.

 

is it difficult to remove the water pump and where should i drill my hole, right in the front?

 

anyone have any info cause i broke my oem sensor in my engine block. and i would like to find a new location. i have had some luck and i can get the bottom of the sensor out i just cant find one in town after the new one broke.

 

The 2nd gen FAQ has links to threads which discuss water temp sensor locations. There are many.

 

give them this part number 8569-18-510A i personally know autozone doesnt list this as one of the coolant temp sensors. they should have it though or can get in a couple days.

where about in wy are you?

 

as long as its behind the thermostat meaning in the block your good, id say drill a hole right next to the stock sensor if you cant get the old one out

 

can it be on the bottom of the block right before it gets back to the radiator? and having no luck finding the faqs for the temp sender

Where do I install the sensor for my aftermarket temperature gauge?
There has been lots of discussion about where to mount water temp sensors/senders. The best location is on the water pump housing near the stock ECT (Engine Coolant Temperature) sensor. Drill and tap according to the threads on your sensor (usually 1/8" NPT). It is important this this sensor be installed before the thermostat. See the following topics for more information:
