Overheating Issue

Hello, I bought a 91 prelude Si about a month ago, it only overheats if I maintain 5k revs or more such as On I-5 doing 85-90MPH (which is how fast it takes to keep up with traffic in my local area due to how people around here drive) it goes hot. If i pop the hood and release steam from the radiator cap, it takes about 5 min to hiss off all the steam, then i leave it alone for a half hour or so and it drops back to normal temp. It's done this twice so far, and doesn't do it if I keep it under 5k... any ideas on how to remedy this? Bigger radiator and a second fan? let me hear your ideas.

Re: Overheating Issue

I have to remember that one for the highway patrol..."I have to go 90, otherwise I can't keep up with traffic!" Especially since 75% or more of I-5 runs through open countryside. ;)

It shouldn't be overheating. A second fan won't do anything -- at those speeds, you should be getting plenty of airflow. Make sure you're getting airflow -- the item you see through the grill isn't the radiator, it's the air conditioning heat exchanger. The engine radiator is behind it.

Check your cap. The cooling system is pressurized, which raises the boiling point. If the cap isn't holding the proper pressure, you'll boil early. Also check the thermostat and make sure it's opening fully, so that you're getting full flow through the rad.

If none of that works, you'll have to switch to a final drive ratio that keeps the revs under 4k. :)

Re: Overheating Issue

^^All of that is good advice, but I'd just replace the thermostat instead of testing it. They are not expensive. Be sure to replace it with one rated at around 190 degrees, no lower. Then refill with coolant and bleed the cooling system before driving anymore.

Changing the final drive ratio is not a fix. The car should not overheat. Fix the problem.

Sorry if my response came across too strong. I saw it but not sure how I'm supposed to interpret that. I probably would have used an appropriate smiley... I guess I just get tired of people not actually fixing their problems and then advising others to do the same. Not that I've ever seen you do that, but in general.
