just installed a new heater control valve.

which hose connects to the section with the arrow? either the hose from the thermostat or what? i installed it the same way as the old one...and everything seems to be working fine so far...but another post here shows a complete different installation.

what would be a symptom of me messing up the hoses on the heater control valve.

sorry no pics..but its cold and dark outside

 

basically i want to know if i installed it backwards can i screw anything up? heat seems to work. no leaks. stays at 210 solid.

 

If it works with the heat selected, and does not when it is turned off,then it is fine,you can also make sure the valve is actuating.

 

perfect! so how do i tell if its actuating? what does that arrow mean? my temp is creeping passed 210 a few times..to about 220 which is unusual for my jeep. i'm going to put new hoses in this weekend so if it happens i need to invert this part...

 

just read online that a four port heater control valve will work either way...but the arrow imprint should be connected to the hose at thermostat housing. that is not how i installed it. i will switch it this weekend.
