If the thermostat is operating properly the radiator will only come into play when the thermostat opens, when the engine is at normal operating temperature (around 190 degrees, give or take). Adding a gigantic radiator won't make a bit of difference because if the engine gets too cold, the thermostat will close, causing the engine to heat up again. In the ...

What is going on in the transmission and the engine under these two scenarios? Coasting: nothing much. The transmission is effectively disengaged (it's more complicated than that but it's a reasonable approximation). The engine is idling - burning fuel to keep itself spinning. Engine braking: the transmission is engaged and the whole system's net ...

In addition to what Patrick said, D3, or whatever else it's called in various makes and models, is also useful for those times when you're climbing a hill and the transmission keeps shifting back and forth between gears. There may also be times, such as when driving on very slippery surfaces, when a gear shift could cause the car to lose traction. In such a ...

This is analagous to down shifting in a manual. This is a lower gear for the transmission which means the engine revolves at a higher rate producing more back pressure at the same speed as a higher gear. When going down a hill, if you downshift that will reduce the demands on the braking system, due to the back pressure. You will often see truck drivers ...

Every manufacturer recommends their own fluids. Everybody wins because your engine gets "less corrosion" and they great great markup on those things. A while ago I did cooling system maintenance (replace hoses, water pump, thermostat, temp sensor, radiator cap) on my wife's BMW 330i. That make/model has a lot of following and several high-quality forums ...

That looks like the front edge of a splash shield (for certain values of "front"). You're right that it is protecting things coming up from below: splashes, sand and general road gunk. It's also likely part of the aerodynamics of the vehicle (admittedly a very small part). The link above is to an example vendor (who's selling the linked part for ...

My knowledge of motorcycles is limited so I could be wrong, but it sounds like the clutch is slipping.

Winter tires in Winter and Summer tires in Summer. With very rare exception the "All-Season" tires are really only very good for 3-Seasons, or for places where the roads are always kept clear in the Winter. Do all 4. Having a mix of Winter/Summer tires will adversely affect handling and braking.

My wife had a 2000 Civic that had exactly the same "feature". First time I borrowed her car, I thought I broke her door. This is how it comes from the factory and by design. The idea is either you lock the door with your keys while you are outside (keys not locked in) or you lock the door from the inside (keys not locked in). btw, I think you can force ...

Holding the clutch in is generally not a good idea. The clutch is designed to be used for very short periods between gears, and for holding in first when you are about to pull away. So if you are wanting to coast you should definitely do it in neutral. The difference between these two from a fuel consumption perspective should be marginal. From a safety ...

For checking codes, any off the shelf obd2 reader will do. If you want to have fun, ELM327 based OBD2 readers are all the rage right now. You can pick up a bluetooth version for ~$40 on amazon or ebay. Several iOS and android apps (like Torque) exist that can read a signal from these adapters and do full on data-logging. This will let you read/clear ...

Your car thinks it is being stolen - jump starting a car looks a lot like hot-wiring a car to the computer. You need to do something that tells your car "it's OK, I own you". You can do this right after hooking up the cables, but before starting the engine, to minimize the annoyance to your neighbors. If you have a remote door key, lock and unlock the ...

Check the other end of the wires to make sure you did not loosen them. Your wires could be going bad and moving them around made the problem worse. Would not hurt to replace them as well. Also it could just be a coincident with the spark plugs, it could be a fuel issue or a problem with your distributor. Although, this is less likely than the first two ...

You don't weigh them against each other. Items are generally inspect or replace at x miles or y period of time, whichever comes first. This is what you need to do to keep the car within factory tolerances. Go outside of that range and you become a "test driver", which may not be an issue, but it could be for certain parts...

What follows is not a mechanical fix. That said, I think you are going to have to solve this as a people problem first. Based on the answers in the comments, I would recommend the following: Collect your maintenance records. Collect your warranty documentation, especially the 100K mile warranty. Write a short script for yourself: "I baby my car. The ...

At least in the United States you are not required to use the dealer for service,parts or repairs to maintain your warranty. You will be required to have the warranty work done at the dealer except in extenuating circumstances,(like the nearest dealer is 150 miles away) but you must still contact them first. If they deny a warranty claim on the basis of non ...

Mostly replacement is preventative maintenance. Eventually they'll get cracks that moisture can get into, etc. If they test good, they're probably fine for the moment, however, at their age they could develop problems any time. On my '91 Toyota, I've been through several sets now, and have to say that in my case, OEM is the best. I've tried other brands ...

Here is what is going on in your scenarios: Coasting in neutral: The engine is running at idle, the gears in the transmission are disconnected from the drive shafts (the drive shafts being what connect the transmission to the drive wheels, which are the front wheels on your Honda). The engine and transmission are suffering no more wear than they would were ...

The thinner radiator might make it easier for the cold air to flow through the engine compartment. (The radiator itself wont cool an already cool engine at all if the thermostat is intact.) In cold environments it is often necessary to use a grille cover to limit cold air flow to the engine. Grille covers are especially necessary with small diesel engines ...

There are silicate antifreezes, used in most domestic cars until recent years, and OAT antifreezes, used in Japanese cars because of their domestic market testing. Domestic cars today all use OAT now, with Chrysler the last to switch. See http://www.sae.org/mags/aei/mater/11284 Any OAT antifreeze will work in a Honda, but don't use silicate antifreeze in ...

I've spoke at length about the benefit of winter specific tires here in Minnesota to my friends far more than they cared to hear. Every single person who has driven one of my vehicles in the winter has come to me afterwards and said quite literally, "I was clueless; I had no idea it makes so much difference." It really does make huge difference, and you ...

It shouldn't be possible for gravel to get caught in the brake itself, but it could get caught in the brake caliper mounting bracket(s) or between the brake caliper and the wheel, the latter especially if you've installed bigger brakes or different-sized wheels. To be certain: look for scoring or other damage to your braking surfaces — that is, to your ...

Upon the regular engine starting key turn area the dash lights dim and there maybe a single 'tch sound or no sound at all coming from the engine block. Sadly, I know this sound well. This sounds like a dead battery. Here are the steps that I would suggest: Charge the battery with a plug-in battery charger. They aren't terribly expensive to ...

You'll find the following will all affect your speed and acceleration: wind speed - a head wind will slow you down more than you would think your clothing - this directly impacts drag bike configuration - you'll go slower with panniers on than with them off weight - a full tank will mean you accelerate more slowly temperature - cooler air can give you a ...

As they are made of rubber, belts begin to perish over time, and this weakens them. The constant flexing as the engine turns accelerates this weakening process. Eventually (if it weren't replaced), the rubber would split and the belt would snap - causing very expensive damage to your engine... It is quite easy to visually observe a belt that definitely ...

Thule makes a rack that fits the Fit. You can then get a cargo box or some bike mounts (my personal choice would be the bike mounts, you may be likely to get more long-term use out of them), or both. It'll be about $360 for the base rack, plus whatever bike mounts, cargo boxes, and accessories you get. I am a big fan of the Thule stuff. Thule vehicle fit ...

Depends on who you ask. Any tire shop will say yes, it affects handling and braking. And it will. But to what degree? Not much. If the tread life of all the tires are similar, the ratings similar, etc. you can reduce this. Still, the different tread patterns will cause different handling. In the rain perhaps one tire will be less effective than the others ...

The manufacture provides a warranty on the paint and corrosion, and what they're selling you usually doesn't extend that. All of the dealers I have worked at sold some kind of paint protection and rust protection. The paint protection was a wax job, a good one no less, but a wax job that you could get at a high quality detail shop for about $150, but they ...

Checking the run-out of the crankshaft is pretty straight forward. A dial indicator is temporarily mounted to a fixed point close to the crank. The indicator arm is set to touch the crankshaft. While turning the crankshaft by hand you will get a reading on the indicator of how many thousands of an inch the crankshaft is moving off of center. Your mechanic ...
