I've got a thermo off an SV21 (camry is it?) for $20. Fits nicely onto the radiator.. just went to autobarn and got some of those plastic thready things ($10) that poke through the radiator to hold it in. works a treat. Then got the relay and temp trigger off an ae92 which switches the thermo on and off ($25). Relieves the little 1.6 a heap!!
