Yes, but it is better if you can use the specified coolant for the year.
You can use any commercial coolant for automobiles or Honda's own coolant.
Use only Honda Coolant unless you want to replace the water pump which will be damaged if you use any coolant with sliicates in it. Also use distilled water not tap water. Honda sells a premixed coolant for around $5 a quart. Money well spent.
Best to use the Honda coolant 50/50 mix.
No, you must use the correct Honda Long Life Coolant Type 2 or a comparable fluid.
The regular universal green coolant.
No. Use Coolant from honda dealership
I would use the Honda pre-mix.
If it is green then any ethylene glycol or universal coolant will work if it is red/pink/orange then use a universal coolant, the mopar HOAT coolant or Zerex G-05 coolant.
You can use universal coolant which you can find in any auto parts store, or you can use a coolant for Japanese card, or you can go and get coolant at a local Toyota dealer.
It should use ethylene glycol coolant. If for some reason you cant find that in the store then use a universal coolant.
Your 1993 Honda Accord can use any SAE certified coolant. The coolant should have a temperature range of -25 degrees Fahrenheit to 120 degrees Fahrenheit.
dex-cool is made for Chevy vehicles but prestone has a universal coolant that works too.
