High speed-Hot Engine

[Guido]

Yesterday afternoon, i was driven on the autobahn, comming from a very nice Beat meet at the german east coast with 16! Beats. I used the empty street to come home soon. But when i drove 140 Ks or more (have got no limitter) the watertemp goes up. When i go slower the temp went back in the middle range, whats is normal. I thought it can only be the radiator, but he is ok, there is also no leak anywhere, no water or oil is missing. The fan works also.
What the hell is wrong with Beatieh?

Thanks for not answering. Realy nice comunity here. Is it why i`m german?
If so, it is realy poor.
Thanks for nothing,
Guido

sorry...

uhm.. maby the speed is to high?
Maby the water has to be replaced?
When the engine is running but not driving the temp is ok?

Probably no replys because no one has any ideas!!!!

Guido, that's a poor attitude and most unlike you! Steve is probably 100% right.

And any way that's bad English, its should be "Is it because Im German" !! :p

Some suggestions for Guido's problem:

Water cooling radiator badly clogged with deposits (likely)
Ignition timing retarded at high revs due to absence of limiter not compensated in ECU ignition map.
Combustion products in cooling system due to faulty head gasket.


Some other suggestions:
Please, no silly comments about nationality or standards of English. This site is all about mutual help, cooperation and respect.

As it has to be limited to 140kph in Japan it is possible the cooling system is not designed to cope with sustained running much above that speed. How hot is it getting and how quickly does it cool when you slow down? Flushing out the cooling system may help. You could try a coolant additive as used in motorsport. Does anyone else regularly drive in excess of 140 kph and do they have problems?

I think this is pretty correct - there are no autobahns in Japan and even on the expressways the speed limit is only 100 or 110. Mr. Honda might have thought it'd be OK to drive faster, but that engine is really spinning at 140 kph and unless you're going downhill it's probably running full throttle, producing a lot of friction and combustion heat for the tiny cooling system to dissipate.

Anyway, a rise in water temperature is not serious until the coolant starts to boil, and then you are in trouble! It doesn't matter much to the metal engine components whether they are running at 70C or 100C (the cooling system is pressurized so it won't boil at 100C), as long as you are using the proper oil. (See the last line of my sig if you need to know how I know this.)

Actually the engine operates more efficiently at higher temperatures, and also the higher the temp difference between coolant water and ambient air, the faster the radiator will lose heat. So unless you do have a leak things work themselves out, sort of.
