Thermostats- 170 vs ?

Hi folks, over the summer, I dropped a new t-stat into my 99 accord 4 cyl. The old one worked fine, it just made sense since I was doing the TB. anyway, I put in a motorad failsafe 170 which is the OEM temp.

Now that its FREEZING outside- I am noticing the cabin doesn't heat up nearly as well as last winter- air blows luke warmish. noticably cooler than what I'm used to.

Is it okay to put in a higher temp stat on the engine? (2.3 vtec)

I have no way of knowing the temp of the old stat- but they make 180 for the car- so it's entirely possible it was higher than 170.

I am going to check the coolant level (to rule that out) this morning and report back- if coolant level is fine, I'm looking for reassurance a higher rated t-stat is okay?

thanks y'all

Per the Haynes service manual, the thermostat rating fully open is 194 degrees fahrenheit. Hope this helps.

so a 170 stat doesn't open until 192??

I checked the Honda service manual. It begins to open at 169-176 Fahrenheit. Fully open at 194.

do you think a 180 stat would help?? just checked the coolant, it's full

The thermostat is one part where I refuse to get anything other than the factory part. They're only around $20, I think less.

Actually now that I think about it, the car I just bought is doing the same thing with the heat. I wonder if they put in an aftermarket thermostat...

Warm your car up and grab your hoses going to your heater core. feel for temp differences.

Hows your radiator cap?

Was stop leak ever put into your car that you know of?

Check the blend doors inside to see if its working correctly/fully opening

OEM ones are pretty cheap. I have a Beck & Arnley 170 degree myself and I am happy.
