Thermostat
Hey I posted this question in the electronics section but nobody there seems to know
I am thinking about using a higher temp thermostat in the car... Stock is 170℉ but I have seen an alternate one at 180℉. I want better heat in the car during winter basically but not if it would adversely affect my engine components. Would a 200℉ stat harm anything?

You can control fan activation if you have Flashpro.
Stick to OEM Thermostat, there is no reason to be changing the temp rate on thermostats. Everything in the motor is engineered operate at that temperature. In any event whether it is inadequate cooling (overheating) or heating problems, you should fix the source of the issue, changing the thermostat is a Band-Aid fix on what could be a larger problem.
If you aren't having proper heat from the heater core, have you pulled the Thermostat out? Most have fail-safe so when something goes wrong they become stuck open. If this is the case, that is your problem. A stuck thermostat will make it struggle to maintain operating temperature, especially in cold climates like you're experiencing now. Is the fan operating properly? cycling on/off at idle?

It only begins to start to crack open at 169-176F, Fully open at 194F - Which is like most Honda/Acura Thermostats. (attachment is for a Type S)

I did replace it, burped it. Heat works fine, it is just not as hot as some other vehicles. Never notice though until its cold out.
I dont have flashpro yet but may some day if i ever get to modding this thing... Would like to do a Sc or turbo. Would the dealer be able to adjust it?

How cold is it where you live? What is your typical driving procedure/distance? Do you let the heat/blower fan run as soon as you turn the car on or something?
TL's seem to have the fury of the sun.

I wonder if the valve in the heater hose running to the heater core isn't fully opening? There is usually a cable running to this valve located at the rear of the firewall, that can get bent or sometimes disconnected. However that cable/wire type setup might be different on the TL since it's more integrated with electronic controls now.
Dealer cannot adjust Fan activation. They would replace a sensor If it failed. The fan usually is a separate circuit where the fan temp sensor has fixed activation/deactivation points ( simply acts as a switch in the circuit). If the ECU does control it on the TL, then its set in the OEM firmware and the dealer cannot adjust that. Hondata is the only way. You could but a universal relay harness with temp sensor to activate the fan manually, bypassing the OEM circuit. You can get ones that have a knob to adjust activation temp. I don't advise doing this tho as changing the Fan temp activation is not the correct solution.
Both my TLs have always had intense heat and really most Honda's I've ever owned, something must be wrong. Did you replace the Thermostat with a OEM thermostat? I don't advise using anything other then OEM when it comes to thermostats

Hmmmm... I had a glance at the hcv and it looks to b in good condition... Heat works at all settings....

I recorded 135F with an oven thermostat stuck in the driver's side vent in my 07 V6 Accord. You have something wrong in the cooling system. I live outside Chicago and during the winter, the heat gets to the point that I'm sweating in the car. Don't mess with the cooling of the engine, you can get into real trouble doing that.

Haha ok Ill do it and report back... Not sure if i have a thermometer but if not I was thinking of getting one for cooking chicken wings (oil temp)

Ok I tested my heat using a meat thermometer in the vent. 142℉ was the hottest it would go with fan speed on 4 bars and car fully warmed up (i.e. running for about an hour with some driving). I dont have the truck here atm so will report that temp later on... I am guessing it will be around 170℉ or higher but will know for sure soon.
btw, it is about 16℉ outside right now.

Alright got a reading in the Ram now. 157℉ is where the needle settled. Its a little warmer out today... 27℉. Setting 3 on the fan speed.
I guess the TL isnt that much cooler. I think maybe because the cabin of a truck is smaller it takes less time to get it feeling comfortable whwn its really cold... Also the leather in the TL is super cold for a while... Like an ice box.
15℉ is still a significant difference though. I also think my TL is working properly, so I know this is not an issue for most ppl on this forum but I live in Canada and it gets very cold at times... On those really cold days it would be nice to have more heat on tap as it has trouble keeping up with the loss of heat through the windows etc.

I will also need something to adjust the fan settings if I do try a higher temp stat... But probably wont bother till the fall.

Oh I do when its really cold out.... Sometimes I try a lower setting to see if it gets any hotter but that is not the case. I believe the hcv is working properly though it is possible that it is not opening as much as it should... But if you test your heat we can have a good idea of whether this is the case?

It just occured to me that I have an aftermarket windshield. I only know this because it definitely is not the same as the one on ny old TL. Actually it got a chip in it shortly after I bought it. Got it fixed at speedy ag because if it eventually needed replacing my money would go towards that cost. Could be part of my problem too.... Although, the dent is barely noticable and it has held up for a year now. Maybe it is an inferior glass and just cannot keep heat in? Do they make such glass? Lol
