fast thermostat and coolant temperature sensor Q's

[beingblueeyes]

will a ls1 thermostat fit in a 5.3?

what thread size is the coolant temperature sensor? is it in NPT?

ok just found it M12 x 1.5 thread size

depends on the year. 99-02 5.3 has thermostat built into housing

03-newer has an old school thermostat.

trucks a 04, I want to know about a ls1 thermostat because a 180 is way cheaper for that then one for a 5.3. the hole thread thing is because I’m trying to figure out how to plum this Hayden Automotive 3651 - Hayden Electric Fan Controls - Application - SummitRacing.com

It's called somedata! I know that an LS2 gto is the standard style that is seperate of the housing.

looks like all ls1 camaros used the thermostat built into housing (just checked performance ones on ebay)


so it'll work on a 99-02 silverado


if you're an 04, the cooler thermostat should be DIRT cheap. Go to a parts store where someone knows what they are doing. They should be able to look up your size and just change temperature. i'll get the autozone number when I go to work today.
