Spring or screw clamps

There are two type of radiator hose fastener commonly used, 1. screw type 2. spring clamps. Most of the vehicle owner prefer to use the screw type clamp, this clamp seem doing the job best. Fortunately for the upper or lower radiator hose which hold pressure this screw type is not the best.

Over the time the rubber (radiator hose) will flatten/shrink but the clamp maintain its condition/position. This will lead to water/coolant spray out within the hose end.

So the best clamp to use is spring type, even the hose flatten/shrink the clamp will continue doing his job, because the spring type keep clamping as hose shrink.

The screw types is also dangerous if you not properly tighten the screw. As you tighten the screw the lower part of the clamps that move will scratch the hose and making hole without anyone notice it. The harder you tighten up the screw the deeper the metal push inside the hose and created bigger holes.

Upper radiator hose and lower hose rock hard

I had this problem since few month ago, the upper and lower hose get so tight like rock hard, then it start to spray hot water from the joint at the engine block, like water sprinkler. I change the new OEM hose and with new screw type hose tighten. Even the hose is rock hard but my engine not overheated. 

After a month the water start spraying again at the same spot. I googled around and found that, most the  cases they suggested to change the thermostat, but after 2 days reading I came out with this idea that everyone should follow if you had the same problem.

1. Check whether there are no air bubble in the cooling system. If problem persist continue to step 2.

2. Change the thermostat, most probably the thermostat stuck closed so the water did not circulate. if problem persist continue stage 3.

3. Flush the radiator, maybe stuck radiator block the water from circulate. if problem persist, hope not.

4. Could be your head gasket blown.

Luckily after done removing the air from the cooling system, my upper and lower hose did not rock hard anymore. At normal operating temperature I can squeeze a bit the upper and lower hose.

How to remove the air? I have done this test on Honda Accord S84/S86 year 2000 2.0cc (6th generation) with factory fitted engine.

1. Remove the radiator cap.

2. Start the engine and run the air conditioning in order to let the fan and thermostat open faster.

3. During the engine running with radiator cap open squeeze the upper and lower hose to let the air come out faster. Repeat the squeezing. Fill the radiator with water if needed.Continue doing this until the fan start to run.

This to ensure the thermostat is open and the water is properly circulate and air being push out from the system.

4. After 15 minutes, turn off the engine and close the radiator cap as usual. Than start the engine and let the engine running for about 10 minutes. Now try to  squeeze back the radiator hose, the hose now is squeezable.

My problem solved by doing the first step only. If your problem persist after doing the step 1, than luck is not on your side so keep trying with the next step.

Hope this help to solve your problem.

How to CF4 bumper and S84/S86

The red line is the cutting line for CF4 bumper which you need to paste it on the S84/86 bumper. But this really need a steady hand to do it. On the other word we still using the original S84/86 bumper but with the CF4 cut on it. Need lots of effort to do it.



But remember once you knock down your bumper you need to standby 2 sets of bumper and of course more $$$ to restore to the same face again.

How ?

Update 17 march 2011 : This model marked on chasis as S86/CF2. Not S84/CF9 as mentioned, but both chasis are the same.

Fuel pump for honda accord s84/cf9

This is year 2000 Honda Accord cf9 / s84 with 2.0 SOHC engine, Few days ago while driving and trying to make a U turn and suddenly after hard pressing on throttle the car suddenly stall and not making any response, rpm remain idle and and gear also not changing.

After discussing with my mechanic and he told me that this might be the fuel pump problem. since the throttle dont response and rpm remain at 1000.This is second time happend to me and luckily the coming car have enough time to avoid from colliding.

The fuel pump located in the rear trunk under the mat.

 Open the cover then you can see the fuel pump  inside, very-very conveniant and easy to install compare to SV4 and SM4 where you need to remove the whole gas tank.

Fuel pump S84 and bracket

The S84 fuel pump with bracket, this small fuel pump which cost me around RM160 + installation RM20. I replaced the new fuel pump from bosh. But I wonder why this fuel pump is the same used by proton wira? Is it enough to supply gas for this 2.0 litre.

Another problem. When starting up the engine the starter will keep on for about 4 second before the engine start (prolonged cranking). Suppose after installing the new fuel pump the starter will start the engine immediately. Dont know why, maybe this few days I am trying to use Denso iridium IK20 spark plug, been told this spark plug good for vtec engine.





update





I have been conned by car dealer or previous owner, they replace the fuel pump with wira fuel pump which is cheaper. 





Reason for prolonged cranking-the fuel pump housing is leaking, so the fuel flowing back to the tank therefor the fuel lost pressure. The harder I press the throttle the more fuel running back to fuel tank. That why sometimes I feel like the engine is going to stall. 

Inflateable seatbelt

A car maker is introducing seatbelts that inflate like airbags to give extra protection to passengers.Ford is fitting the back seats of vehicles with belts that inflate automatically during a crash.

model show how it work

Experts say they will be particularly effective at preventing broken ribs, internal damage and bruising in children.Frail and elderly passengers will also benefit particularly from the cylindrical airbag that stretches from the buckle to the shoulder and fits inside a pocket sewn into the belt.The technology will be introduced on the latest model of Ford Explorer 4x4, which goes into production in the United States next year.If the trials work well it could open the way for the belts to be used in Britain.

The Audi calamaro flying concept car

Audi Calamaro

The Audi Calamaro Concept was developed by a designer Tibor for a design competition, organized by Porsche Hungary. This futuristic flying concept car looks like a cross between a speed boat and a plane. According to the designer, the shape is inspired by “the bone of the cuttlefish”.

Audi Calamaro concept

We can’t see any propellers, tires or thrusters. We can only assume it will be powered by a new type of power source that hasn’t been developed yet. It is a very interesting concept, but in addition to the unknown futuristic engine it makes us ask how will it park or turn? Perhaps like the cars in Back To the Future sequel.
