Guys I need help my 07 tl type s the engine temp gauge recently starts to rise a little after i drive for about 30 minutes so i checked my coolant and its still good and my radiator fans still work i’ve noted that i have been leaking water from the passenger side a little but i think thats the AC i took it to a honda dealer and they say blown head gasket in the front and back about 2800$ I dont wanna get cheated pls help

 

Have a cylinder leak down test performed; that'll tell you if it is a head gasket. That said, I might be inclined to swap out the thermostat and see if that fixes our issues.

 

Do the leak down test I Think if the head gasket was bad you would be losing coolant

 

Take it to a indy shop to get a cheaper quote.

I recommend a compression test. It's faster than a leak down test. You can also pressurize the coolant system to try to find a leak.
