What gaskets do I need?
What gaskets do I need?
What gaskets will I need to change the thermostat and coolant temperature sensor? Where can I get the thermostat, gasket and sensor online for a reasonable price. Plus what temperature thermostat should I order (170°?) If possible can someone post an image of the gasket or gaskets?

Re: What gaskets do I need?
@sdaidoji ngl, your response led me to IAT stuff, not t-stat and coolant temp stuff.
OP, whatever thermostat you buy should have the necessary o-ring on it. Similarly, the switch should have the o-ring, as well. You shouldn't have to buy any extra gaskets, assuming that's all you're replacing.
If you want Honda OEM, the thermostat part number is 19301-PAA-306 (OEM spec is 170F) , and the coolant temp sensor is 37870-PLC-004

You will see that I already answered his question about where to get parts online in that thread not so long ago (they are from same poster)
Re: What gaskets do I need?
I just wanted to make sure that I didn't need the whole housing gasket..the thermostat separates from the main housing.. one small round gasket needed. Thanks
