I have a 2000 Civic SI and I live in the FL heat. What suggested radiator fluid with a 1.8 block and 1.6 head DOC port and polished. The rest is pretty much stock.

 

OEM. You're overthinking this.

 

If you are concerned you just increase the ratio. Instead of 50/50 you do 60% coolant to 40% water. Just be sure to stick to Honda or "Asian Vehicle" coolant when you go looking for the concentrated stuff.

Something like this:
MotoMaster Asian Concentrate Coolant, 3.78 L | Canadian Tire

 

There's no real reason to be concerned. Water Wetter is also an option, though, if you really are.

 

So moto master is the best ? Y can't just use water in Flordia it will never freeze u no

 

Oh yay, another member that wants to ask questions, then completely ignore what he's told. Why did you even bother asking?

Water is corrosive. Coolant helps prevent corrosion. I'll say it again, since it didn't sink in the first time. You are overthinking this. Just get OEM fluid and call it a day.

There ya go.

 

how do i make sure air pockets our out of coolent system i dont have temp gauge no one on here can figure out so i ordered new cluster gauge but for now so i can drive any other tricks besides turning heat on and running because no gauge

 

Put the front end on jack stands, or park on an incline. Turn the temp slider all the way to hot (you don't have to turn the fan on). Take off the radiator cap. Start the car. Let it run for 2-3 radiator fan on/off cycles. It should take about 15-20 minutes. Keep it topped off while you're doing this. It's that simple. As for your temperature gauge, make sure the single plug on the head, directly under the distributor, is plugged in.

 

In addition to the corrosive aspect NAR mentioned, coolant also raises the boiling point of the fluid so it doesn't boil as fast as water. As well as it's a lubricant for the water pump.

Running straight water is worse than you are aware, it isn't just about freezing.

 

ty bud on filling .... the wire is pluged in what happens is when i turn key gauge goes all the way u slowly past hot its retarted lol so i changed sensor also still the same last owner had wires goin to fuse box have *** like intorior blue lights and **** so might of hurt gauge no gas gauge on that side dont work eaithr what do u think

 

If you've replaced the sensor, and the sensor is plugged in, assuming you're looking at the right one (it's literally the ONLY single wire sensor in that location), either there's something wrong with that single wire going to the cluster, or there's something wrong with the cluster itself. Given your gas gauge doesn't work, either, I'm leaning towards cluster, but you'd have to test the wire to properly rule it out.

 

I think you might want to go to helminc.com and purchase an Electrical Troubleshooting Manual (ETM) if you have plans on keeping the car. They aren't very expensive and are a god send for the electrical systems.

It will allow you to undo and isolate fubar wiring of previous owners.

 

Or just Google "Civic FSM download" and click the second link

 

for 38 bucks i should try gauge first then get that trouble shooting right car has no cut wires or nothin just stupied kid lights lol i un did
