water pump (has a pin hole overflow if goes bad) , water hose connection, overheating, damage to the radiator causing a crack?
the lead that goes to radiator came out, when l put back in would not hold and now leaking, water pressure was low and water is funny colour (kinda red)
The water is boiling in radiator because it's temperature(radiator's) reaches the boiling point of water when the engine works for a long time.
The lower radiator hose supplies the water pump. The upper radiator hose supplies the radiator.
Radiator caps are pressure relief valves. They are rated at "pounds per square inch" and are designed to release some pressure from the radiator if it gets too high. If an engine overheats it can boil the coolant and this will cause the radiator cap to let out steam. Radiator caps DO lose their ability to regulate pressure and can release too soon. If the engine has not overheated, have the radiator cap tested and replaced as necessary.
The process of the engine creates huge amounts of heat. Water is past through the engine block (that is where the cylinders are ) where it collects heat from the case body of the engine block and its taken to the radiator where air is passed through the radiator cooling the water. The cycle continues. If the water did not circulate then the engine would expand considerably, the cylinders will also then expand as would the moving parts to the point where the friction would cause the engine to cease up.
your 2001 Honda odyssey lose water
coolant in engine enters radiator at the bottom, goes up thru radiator and exits radiator at top. i would think your radiator is clogged up try a good,(expensive) radiator flush to see it that fixes proble,
There are several reason why a car might lose antifreeze. The water pump might be bad, one of the radiator hoses could be leaking, the radiator could have a leak, a freeze plug could be leaking, or it could have a blown head gasket.
you would lose all your coolant
I assume you want to change out the water pump and would like to know if you can do it without draining the radiator. You will lose approximately all the coolant in the radiator reservoir when you remove the radiator hose from the water pump. If the coolant is in good, clean condition, it might be wise to drain the radiator into a container and re-use the coolant.
there is supposed to be water in the radiator. your radiator is supposed to be evenly mix 50/50 with radiator fluid and water, preferably distilled water.
The most common reason for overheating of a car radiator is that there is not enough water in the radiator. Radiators can lose water in a variety of ways, and often need to be refilled. The other possibility is that the water is not being circulated properly. I should add that cars do heat up quite a bit in the sunlight on a hot day, which adds significantly to the chances of overheating the radiator.
The antifreeze is building up to much pressure you may have a cloged line or tour hose clamp is lose
It means you have a "BIG" leak. I would check the bottom of the radiator or the lower radiator hose.
There is a water reservoir tank that goes to the radiator that you can add the water to.
Because it would cause the universe to explode
No. The only times the radiator would leak is if it was damaged, defective, or corroded.
