Replacing water pump LS1 Hi,
I´m in progress to replace my OE WP.
Read some thread saying WP today are LS2 replacement and you must also purchase new Thermostat and Thermostat house.
I have ordered this WP from RA:

Do i need to order new Thermostat and Thermostat house for above WP?
If yes, is this the correct part?

back in about 2006 i replaced my h2o pump not knowing they stopped making ls1 pumps, only option was a ls2 pump which my $50 hypertech 160 therm didnt fit! grrrrr the pump bolts right up but NOT the original ls1 therm housing.
