Water temperatures?

[MR-VTEC]

hey all,
firstly i did a search but didnt really find what i was looking for in particular so....

well this is my concern i recently aquired a new car and it is equipped with a microtech dash unit anyway so while i was driving i was keeping an eye on my water temp and when i stopped in traffic the thing hit 98 degrees celcius i wasnt even sitting there very long. well the fan kicked in and it went down to 94 but even still isnt that pretty high. on the highway it sits around 90-92.

so when i got home i checked the coolant levels and hoses and the overflow bottle and they're all fine so i got no ideas:confused:

1. should i be worried?
2. should i get it checked out by a mechanic?
3. any sugeestions you have would be appreciated.:thumbsup:

hmm, 90+ degrees is common from my experience.

although it does seem a bit high for NA. Maybe you have a dicky thermostat, perhaps check out that avenue first

My near stock B16A2 runs 85C - 95C in normal driving. Constant high speed gets up to 100C, and high speed overtaking i've seen up to 110C.

If you give it a bit of stick then stop at the lights, the temperature will soar. It's natural, it needs the air to cool it down. I'd say watch the water levels and if you're worried, mention it to your mechanic at the next service.

thanks for your responses people. so you all reckon it's ok then? no need to worry? also at what temp will the coolant boil? i thought it wasnt supposed to go over 100 degrees c.

coolant makes the boiling point of the water higher... like approx 110C

same was when u put salt in water it makes it boil at a lower temp.....

the moral of the story is never put salty water in your radiator :)

also (i think) when the water is pressurised in the radiator and piping etc its boiling point will increase.

Correct.

Coolant acts as a rust inhibitor/increases the boiling point. Putting the system under pressure ALSO increases the boiling point.

cool so i dont need to worry?

Any ideas what the boil point actually is with the stock radiator cap pressure?
