Anyone out there install this after market thermostat on their TL ? Any improvement on your gas mileage?
Many thanks for any helpful info.

 

Your best bet is to buy the "OEM" 2-stage design T-stat for overall trouble-free results.

 

The OEM works for me even at +120°F so Id stick with it.

 

Thank you. Where to check it out? Do you have it on your TL?

 

I remember my temp needle nearing 4/5 on the OEM thermostat at a one time trip leaving vegas. This is what's prompting me to try a cooler running engine. Thank you though .

 

I live in San Diego but do lots of trips to Arizona so I know your feeling but seriously the stocker T-stat has been a champ in those horrible summers we get with full A/C and luggage so its been alright.


Id try to flush the Anti/freeze and make a full change and replace t-stat. FYI the stock is the 2 Stage but they wear out so you should replace it.. If you feel your system isn't working its best you might wanna do a pressure test cuz your Water Pump can go wrong with age.

 

Yeah, as Skirmich said......have the cooling system pressure checked, replace the coolant and T-stat.

Also, make sure that both of the cooling fans are properly activating. If you're temp guage is over 1/2......something is not right.

 

Sounds like the right way to get started.Ok then I'll change my coolant fluid and replace the thermostat w OEM first. I should have enough time and observe how it performs over time.Thank you all for your kind replies =).

 

If your Temp gauge read that high you have other things to look into as issues than trying a lower temp t-stat. You need to make sure your radiator is clean and not plugged up. Flush it with a hose washing all the debris from inbetween the fins, Make sure your coolant is full, and make sure your fans operate as they should.

 

Will do....my next project. Many thanks again.
