    Slideing the cap down is important, make sure when the cap is slid down ,the impella should be already in the cap and turn anticlockwise as it is put in place. Honda 50 : anticlockwise

SOURCE: 2005 Honda Civic No heat at idle but have heat

sounds like a circulatory problem. at the back of your engine compartment there should be two pipes connecting your matrix to your water system. it used to be common practise that when your matrix went to just connect them together and bypass as the dashboard has to come out to repair.

SOURCE: 1995 honda civic, while driving engine gets hot & cold?

I used to have this problem too on my 95 Honda Civic EX. It would get hot then it would cool down when I stopped. I replaced the thermostat and it took care of the problem. I am not a mechanic but it was real easy to change out. I bought it at Auto Zone and they even gave instructions on how to replace it. Also don't forget to buy the new seal for it. Hope this helps.

SOURCE: 98 honda shutts off and will not start until cooled off

you say the engine shuts down when it gets hot if it runs rough before doing so it could be the coolant temperature sensor allowing the engine to  overfuel  if the engine cuts out in a couple of seconds but sounds smooth it could be the fuel pump , if it cuts out instantly its electrical.

I thought one was overheating but it turned out that the 9 volt regulator was fried and was putting 12 volts to the temperature gauge. Temperature was really OK. The fan switch is probably not lying

Is there a speed limit for airplanes?

There are some speed limits for certain types of airspace. Airliners are always in contact with air traffic control and in order to keep the required separation of aircraft sometimes the controllers will ask the pilot to maintain an airspeed. More than likely you experienced a slowdown while your plane was beginning an approach, During approach controllers have to maintain specific spacing between aircraft and often must slow them down behind slower aircraft. Your plane very likely was slowing down from approx 570 knots to 250 knots or less for the approach.

R reg toyota previa over heats. had new pressure cap n tested the head gasket so both of them are fine. is it likely to be the water pump? as its worse wen Im startin n stopping but seems fine wen Im...

It appears that you have a viscous fan hub driving the fan or should I say failing to drive the fan. The fix is to replace it . If you have electric fans then there is a problem in the temp sensor system and the fans are not cutting in on temperature The problem you state is indicated by the fact that when driving there is sufficient air through the radiator to remove the heat from the radiator ..but when driving slow there is no air flow because the fan is not drawing air through the radiator and the temperature climbs until over heat is reached . Typical indicators of fan speed problem is overheating at stop sign/lights, slow heavy traffic driving, slow up hill driving, and rapid cool down as road speed is increased , the faster the speed the cooler the motor

2002 montana the temp gauge stays in the middle but when i drive it and come to a stop i lose heat i replaced the thermostat and water pump flushed the system refilled and purged what eles could be wrong

your heater core may be partially clogged up, when you come to stop the engine speed slow down and so does the water pump. therefore you don't have enough flow until you hit the gas and the engine rev up again

Washer will not spin properly

Try this:
The filter on your pump is probably clogged with lint and stuff. You have to remove the bottom front panel, 3 torx screws underneath. The panel will drop and come off. Drain off the excess water from the drain pipe you see. The white filter cover is right in front. Get yourself a good plastic bag to collect water. Unscrew the filter cover and twist the filter out. Clean out all the stuff and put it back in carefully. Check your pump too.
