Engine overheat
Okay guys, my car was running fine till yesterday when I decided to change the climate control from red to blue (mind you I have no AC, it was just blowing in too hot of air even tho the climate control was set to off but you can still feel it). Anyways, as soon as I go to blue, the car starts to heat up quick (goes way over half, a little under H). I cant tell what the problem is exactly but when I go to red again,the car cools down to operating temp. Its a 1997 ek with jdm b16a

check your thermostat, coolant level (replace it if it really old) and fan. The reason your car in fluctuate based on your climate control setting is simply because by putting it on "red" you are preventing the engine from overheating by allowing the heat to vent into the cabin.

exactly. Here is the thing, if I leave the car idling for a bit while revving it, the fan will kick in. But when I drive and the car is overheating, the fan is not running or turning on, I dont know why. The coolant is new and was flushed properly and there is no air in the system (I know for a fact).

I have a similar problem, except my coolant is disappearing 
took it to honda today. they say i have to replace the head gasket theres a leak, also one of the cylinders is misfiring. and since they are doing all that also they recommend getting the water pump, timing belt done too as they are due to be changed soon. there goes rims budget

change out your heater core and thermostat. most of the times your water pump and timing belt arent the problems. they recommend changing at 60k dont worry about it. there designed to last alot longer. just a big money grab.

I would dis-regard this post. Classic case of someone posting up mis-information.

i may have been alil hard on the water pump and belt words. when its recommended to change ppl dont read the fine print. its 60miles. which is 100kms, i konw i said 60kms my bad.
my old 89 civic went a good 150kms and the only thing needed was heater core. asked my mech and he told me waterpump and belt were in fine working order.
then again its all up to whoever pays out the cash to shop that ripps ppl. i konw of many being in the biz

Yeah, you're right. Replacing a belt before it snaps that will damage your engine is a rip-off. All mechanics are out to rip you off.
I've seen belts snap at 90,000km, I've seen them last 200,000, zeeman's snapped at 40,000km. Every belt is different and there is NO way to examine a timing belt, the cords tear internally. Regardless of what vehicle it is, a timing belt needs to be replaced at 100,000km. If yours last longer, that's great, but what if it snapped? Wouldn't you be upset at your mechanic for not telling you to replace the timing belt?
Sometimes I feel like no matter what I do, people will always think mechanics are out to scam you. Don't tell me you know many things about the "biz" cause it sounds like you know nothing.

Simpleist To replace is the Thermostat. The reason they are so cheap, is because they are cheap. When you open your cooling system to HOT from climate control, it's allowing fluid to pass through you heater core... In a sense it acts as a secondary Rad.
It possible to buy a thermostat, and it be already busted, never seen it, but heard of it nonetheless.
When a heater core goes, your car can fill with lovely fumes of death, and you'll notice a nice layer of greasy gases on your window (Extreme case)
An unexperienced mechanic can change a Thermostat in about an hour... Jack the car up, realise your bucket wont fit, find something else to use, can't reach the 10mm bolts, hoses are in the way... Now I'm covered in rad fluid, and the chicks think I smell like french fries...
A Timing belt will make a 'smacking' sound nearing the end of its life, sometimes. But it's probably something that would need to pointed out to you, not just listening to your car and thinking you hear something. And this isn't 100%.
Those missing fluids, you can usually tell when your head gasket is K/O'd. White Smoke from the exhaust if the fluid is being pushed into the cylinders. Start your car, remove rad cap, and watch for bubbles from the rad once the cars at operating tempature, means headgasket, air being forced out. And occassionally oil mixed in with your rad fluid.
A not so common mistake, check your mix levels Rad fluid vs. Water. Rad fluid isn't ment to keep your engine cool, it's ment to mix with water to raise the waters boiling tempature, and pervent it from freezing in the winter. Rad fluid doesn't cool your car down. There are products like water wetter which is used in 'race' applications, but it NOT ment to be run in cars at winter time.
As for mechanics ripping people off. My Dad is a honda tech. and I know he doesn't rip people off. I worked at honda with him, and I know SOME mechanics DO rip people off, even little old ladies. I worked at Canadian Tire Bowmanville and I know THEY rip everyone off. That being said, some people want their car running at %200 new, others just want their car to run... A Mechanic will tell you anything wrong with your vehicle... But the good mechanic will tell you what you actually need to have your car safe, reliable, and not a danger. Mechanics should never force you to do anything/buy anything/ or upsale, unless you want it.
