1996 Honda Civic Hot temperature (only for high speed - lon

Your vehicle is not capable of heating and cooling down that quickly. It sounds as though your temperature sending unit is failing.

When the vehicle's gauge reads that it is overheating (in the red), turn your A/C on. If it blows out cold air, then your vehicle is NOT actually overheating.

Your radiator may just be weak at those high speeds. Is it the original radiator?

Hi chezunee,

Seems the radiator is partially clogged resulting in inefficient cooling when the engine is worked harder.

I would suggest getting the radiator serviced and coolant replaced.

Look at the front of the radiator, are the fins all bent and damaged? Usually this will not cause any a problem with normal use-age, but obviously your speeds are above average so you may have a weak radiator, clogged rad, poor flow to the rad (leaves, debris, bent fins, etc) all these things can cause poor cooling issues at those high speeds. I am definately leaning towards a poor radiator for this issue.

As for your oil consumption, you may have an internal problem. It may be, valve seals, piston rings, cylinder walls, etc. For this problem, I would first check for an oil leak (cam seals are common, oil pan gaskets are also) if there are no leaks then I would investigate the PCV system. Is the valve functioning properly? Is the vacuum source collapsed? If all these checks are good, then I would do a cylinder compression test. Even if the compression test checks out, you still may have a valve seal problem! With your type of mileage there are many possibilities to where your oil is going. Do some checks and reply back for further guidance!

Hey don't give up now, look how many people are trying to help you :) We won't give up, so try and hang in there. We'll try and save you as much money as possible and get your ride going again without overheating. Post the results of the radiator change and if it still does not help, we will dig deeper into our resources until we can find the issue without you replacing part after part.

Yep, we would not leave anybody hanging till we have exhausted our resourses.

If the radiator is partially clogged, it would cause high speed overheating. Seems we are nearing the solution and the last step should get the problem solved.

MERRY CHRISTMAS

That is awesome news. Let us know how the trip goes.
