Going to do a coolant change on my 2007 Honda Accord 2.4l with 131k on it.
I'm still running with the original top and bottom radiator hoses, and figure that changing out those hoses and clamps would be good preventive maintenance while doing the coolant change.
My question is , should I change out my thermostat and coolant temperature sensor in the process? Do these fall under scheduled preventative maintenance, or the if it isn't broke don't fix it category?
My deductive reasoning tells me that it would only make sense since the cooling system is only 2nd to oil changes to ensure extended engine life. Am I correct in this thinking?
Also, are the thermostat and coolant temp sensor the kind of parts in which you only want to replace with OEM?
Thanks,
Grant
I changed my thermostat at 133,000, I got the part from Honda. I would not buy after market for that. However I did not change the hoses. I also used the Honda coolant. I did it in 2016 and the thermostat cost $130.00 at that time, I am sure it cost more now.
Thermostat should certainly be changed after nearly 15 years. Temperature sensors I generally don't consider to be a maintenance item, but you could certainly do that while in there. They're usually not very expensive. OEM parts are preferable.
Thanks Chuck! Yeah I wasn't sure on that coolant temp sensor. I just figured since I'm already in the neighborhood doing the other work and it not being overly expensive, just do it. It's my commuter car and on a typical day I put about 115 miles on it now.
Greatly appreciate your input 👍
I agree with Chuck. I change my thermostat whenever I do a coolant change, about every three years. I always use an after market fail safe thermostat just for quality. That way, I know the engine can't over heat.
Yeah Doc, that was thought behind doing it. Ensure that I'm taking away the probability of engine overheating. Greatly appreciate the input 👍
I would also strongly suggest a new radiator cap to preclude excessive pressure build up in the system. If you get lucky with a bad cap, you'll just blow a hose. If you don't get lucky, you'll blow a head gasket. $$$
If you live in a hot climate, you may consider putting in a lower temperature thermostat to let the engine run cooler. I put a 160 in my Florida van and now the engine runs nice and cool in 96 degree heat. Some would say you will lose some fuel mileage but I haven't noticed it.
Just a thought
Fortunately or unfortunately depending on how you like your weather, I live in a 4 season area . Don't think that would benefit me a whole lot. Great tip for those in hot climates though. 👍
In my truck, the specified thermostat is 195 degree but I use a 180 degree.
you do know that hotter engines make more power right?
