Hey guys I have a 06 2.4 manual type s. Water pump pulley bearing died so I decided to do a big overhaul since I’ll be changing it. I changed the water pump, idler pulley, alternator, starter motor and serpentine belt.
Long story short, after refilling the coolant and following the bleeding procedure as per hondas instructions no I’ve noticed the thermostat isn’t opening, the bottom rad hose is cold and the top one gets hot. To top things off the cooling fan is no longer turning on (as the temp sensor is before the t stat I would think the fan should still come on regardless if the t stat isn’t opening.) I’ve also noticed when I turn the ac on the condenser fan also does not come on.
I’m ***uming as all worked prior to this maybe the t stat isn’t opening due to airlock (inside the car I can hear water sloshing behind the dash), regarding the fans I’ve done the basic fuse/relay checks, given both fans direct power and turn on. Only thing I haven’t tried is jumping the temp sensor switch plug to see if it turns the fans in from there.
Have you guys any ideas on what my next steps should be? Any bleeding secrets? I spent hours trying to get the t stat to open. Could it have gone bad? Doesn’t the car throw a code for a bad t stat? Any help is much appreciated. I did read there is a drain plug under the t stat somewhere, is this accessible? Was thinking of cracking that open to see if it helps get air out but I can’t find a location for it anywhere all I know is that it’s there somewhere
