Today I got bored so I swapped out the thermostat.
Tools needed:
Socket wrench
Socket extension
10mm socket
Liquid gasket
Razorblade
Water outlet houses the thermostat.
Use a 10mm socket to remove the water outlet.
After I removed the bolts I had to man-up on the water outlet to bust it loose.
OEM thermostat. Note the position of the jiggle valve.
Pull it out.
Replacement thermostat.
Nismo vs. OEM-if it's anything like the suspension parts then it's a highly overpriced copy of the stock part.
I got a razor blade and removed the leftover gasket on the water outlet and the block.
Place the replacement thermostat in with the jiggle valve upward.
Get some liquid gasket ready and put a 2-3mm bead around the water outlet neck and position it on the block then hand thread the bolts on tight and let it sit for an hour.
Come back after an hour and then tighten or torque to 2.7-3.7ft-lbs. I didn't use a torque wrench here on account of possibly busting something...it's only 2 to 3ft-lbs. come on.
