Run the Honda until the wheels fall off! a 2007 Honda will run for a long time with this issue.

Unless you are made of money run the Honda and bank $250/month like you have a car payment and a car you are proud of. Every time you worry about the Honda look at the bank account and run the Honda for another week.

Keep changing the oil, checking the fluids, new hoses as needed, rotating tires... basic stuff.

The death neels for this car are a coolant leak or oil leak/usage. until one of these happens keep on driving. When it leaves you on the side of the road. reach into that big bank account that has been building $250/mo. and go buy a new Honda (if it still meets your needs size wise)
