Need to know what the evap hose looks like


A/C systems have two hoses, a smaller diameter one for high pressure and a larger diameter one for low pressure. High pressure freon is compressed in the compressor and and pumped under pressure in the smaller hose to the evaporator where the freon is expanded/evaporated and becomes cooler via the expansion process. Here the freon absorbs heat. The larger hose then carries the expanded/evaporated freon to the radiator where it is cooled, then on to the compressor.

Radiator hose pressure


Radiator hoses that are expanded past the hose clip are about to burst and must be replaced . The rubber developes a slippery surface and the pressure exerted by the hose clamp is insufficient to hold the hose on. The hose rubber itself has little resistance to shape change so as the pressure increases the hose just slides off out under the clip. Place new hoses on dry clean surfaces (no rubber grease)---use new clamps ( preferably clips that have a hex head. as well as a screw driver slot or star as the socket will get the clips a lot tighter than a screw driver) The bottom hose will be the last to go as it is under suction when driving and only comes under pressure when stopped and the pressure equalises in the cooling system. Replace any hose that is bigger then the clamps as they are waiting for the chance to catch you out.

MY BMW E 46 HAVE EXCESS PRESURE IN COLING HOSES BUT TEMP IS NORMAL POSSIBLE CAUSE


Check the temperature sender unit as expanded hose indicate excessive pressure in the radiator form heat. Check flow rate through the radiator as there may be some cores blocked restricting full flow.. If the hoses expand outside the hose clips then the internal bradding has failed and eventually the hose will burst. Good hoses do not expand past the hose clip and are the same size as the bit on the housing. I would be checking engine coolant level in the radiator and not the reservoir as a temp gauge will read normal when there is no water in the system

Leeking antfreez by intake gasget


Check that the antifreeze is coming from either a freeze plug which is round and about 1-3/4" in diameter, or the head gasket.

If it's a head gasket, it will have to be replaced.

If it's a hose leading to the intake gasket area, replace that part.

If it's a freeze plug, then a rubber expanding one (with a screw in adjuster) may substitute for the original metal one.

Good luck on this repair.

Radiador hose that goes to filler cap keeps poping off


Hi.
If I am reading this correctly you are speaking of the overflow hose to the reservoir. As your coolant heats up it expands, when the pressure goes over the rated pressure on the cap in flows into the reservoir. When the coolant cools off when shut down the vacuum created as it cools pulls the fluid back out of the reservoir.There should not be enough pressure in this hose to push it off unless the hose is too soft to hold.There must be a blockage in the hose or in the reservoir itself to create this problem. Dirt may have gotten into the tank or hose or the hose is pinched along it's length.
After you have located and repaired the problem a plastic tie strap could be put on it .
Hope this helps you out.

I'AM LOOKING FOR A DIAGRAM OF THE COOLING SYSTEM; SO I CAN DISCONNECT THE HEATER HOSE AND USE A WATER HOSE TO RUN THROUGH IT TO SEE IF ANY DEBRIS ARE TRAPPED BLOCKING WATER FLOW


This is how I flush the heater core...go to the garden department at Wal-Mart and get a 5/8 - 3/4" female garden hose connector similar to my picture...remove the upper heater core hose and connect your garden hose to the connector then to the heater hose and secure with a hose clamp. Remove the lower heaer core hose and point it to the gound, then turn on your faucet and run clean water thru it... b67bfc8.jpg
