I was cruising at around forty kilometers per hour when suddenly it just lost power and could only go about 6km/h. Motor is fine.

Good Day,

Sounds like the thermostat is working properly, the only other cause for the valve/lifter noise could be the oil pump is not pumping enough oil up to the top of the motor. I suggest doing an oil change(if you haven'y aleready), be sure to flush several quarts through, after sitting for 5 years I'm sure the old oil is pretty sludgy, this well help rule out this possibilty. As far as the water pump goes, It either works or doesn't typically when they are on there way out the will leak from the gaskets. A bad head gasket would cause white smoke form the exhaust as coolant get's into the oil and is burned off, so I don;t hink this is the problem.

Here's a start for you, hope this helps and good luck

Your alternator is going out on your car. You need to get a new Alternator

SOURCE: engine stalls

my friend had one that did the same and he replaced throttle positioning sensor and it fixed it. but when you put a new battery in them they wont idle until you hold at steady low rpm for almost a minute because it has to relearn its position. so check your voltage meter and make sure it is around 13-14 volts when running and not on 12 while running because it could be too low of voltage for it and would be the same principle as disconnecting the battery because it takes 12 volts to keep computer on. hope I wasnt too confusing but I just want you to check your voltage for free before you buy electrical parts.

Go to the aerogrow aerogarden website they have step by step instructions on how to fix this problem. I had the same problem and was able to fix it by following the steps outlined there. http://www.hydroponicgardens.net

usual if the pump is dry you need to try bleed get some water to the pump. either pouring some in the lift pipe some pumps have a bleed screw to pour into to get it pumping. if it still wont could be the fins in the pump that are not working proper
