Is it safe to drive if there's only water on the radiator and reservoir?

[dak_air]

Hi Guys,

I would just like to know if it is safe to drive if there's only water on the radiator and reservoir?
As my reservoir exploded and made the radiator drained?
Can you please advise what I can do to prevent overheating?

I just replaced the reservoir and just put water from the time being.

**What type of coolant do I have to buy?
Civic 98 eJ8

Thanks in advance.

It is Safe to drive with just water in the radiator for now,
If left for a extended period of time it will start to cause corrosion though

So just swap it out with coolant as soon as you can it will be all good.

grab a 5L bottle of tectaloy 90 plus from supercheap for $19.99. good stuff

Thanks for the reply guys...
Just to make sure does the reservoir needs just water or coolant as well?

coolant.

coolant
water isnt as effective
if you idle for awhile it might overheat again

make sure to completely drain the system before refilling with coolant.

difference is coolant doesn't boil and water obviously does. it's fine to run temporary but change if asap

and water causes metal to corrode and coolant doesn't (corrosion inhibitor)

Water is fine for short time. If u r scare of overheating, then turn the heater to full.

Coolant does boil, just just boils at a higher temperature.

Don't get coolant with only anti corrosion, you need coolant with anti corrosion, anti boil & anti freeze. I would recommend you go with Nulon coolant.

I think what u need to identify b4 going out buying coolant is what caused your coolant reservoir explode!

Its obvious that there was too much heat and engine overheated due to a number of things.

If ur going to buy coolant - buy two 5L bottles incase u leak again and a new/2nd reservoir.

Inspect or replace your thermostat while your at it. Unless u knw exactly when it was last changed.
