    Engine over heating. Replaced radiator, water pump, hoses, thermostate. I have flushed the engine with muratic acid and water. I am not getting good flow in the radiator. Should I flush it again? The water is clear and appears to be clean.

It seems that the water lines in your engine block has got a lot of sedimentation. Try a mixture or liquid which is locally available for unclogging your water lines. Maybe Muratic Acid/Combinations might work or use off the shelf available which will reove these scaling. Once the water passage is clean then the engine at large will not overheat and neither will you blow the hosepipes which are bursting now due to overheating in pockets causing steam to be generated. So basically you have to get your engine block water cooling lines to be cleaned of sedimentation and calcification. Once removed your engine will not overheat. Finalyy to finish off pput new hosepipes to avoid it failing due to execesses of the earlier condition......sodeep

My 1999 dodge caravan is still overheating. I have already replaced the thermostat and the water pump, also there is no heat. please help me someone!


Hi there.
Well you can either have a problem with either radiator outer {dust/dirt in outer core of radiator or clogged up inside were water goes, or soft hoses,blowen head gasket plus a few others ,but first go to garage to were you blow up your tyres and use the air hose and blow out the radiator core where the air goes in, 2 drain out radiator water and then refill with water at 1 ltr at a time and then check your info car book and find how much water the radiator takes ,if it dosent take all the ltrs then the radiator is blocked inside.
if engine runs rough missing etc then get your Head gasket checked out.
When you say no heat is that with heat on gauge or no heat from heater, as it could be heater blockage same as radiator core. So let me know how you get on.

What should the temperature of the heater core inlet hose be?


heater hoses run from the rear of the block to the water pump. One hose into the heater should be hotter than the other because heat is transferred in the heater in the car. . The cooling system draws water from the bottom of the radiator ( water pump inlet)which is always cooler than the top hose and dispenses it throughout the engine and heads including the heater core. It is then pushed past the thermostat with all the heat from the engine to the top of the radiator where it is cooled down by the air passing through the radiator . Check that the air vent for the cabin is set to recirculated cabin air and not fresh air from the outside as it will require recirculated air to increase in temperature to work properly

I have replaced radiator, hoses, water pump & thermostat on 1994 BMW 740i and the antifreex is still leaking, What do you think is the problem?


do you have smoke out the back esp from cold and still wen engine is warm?if no visable marks from core plugs or hoses then you may have a head gasget fault or it could be leaking out the heater matrix.check carpets for dampness or condensation.check to make sure all pipes and radiator are hot all over.water pump and thermostate not common faults on the 7 series.sounds like you might need to dig further.

No heat in my 97 dakota noticed when motor is warm both of the radiator hoses are cold what is causing this


good day, heater core/coil is leaking antifreeze and needs to be replaced. The heater core works in conjunction with your engine's cooling system. The function of the cooling system is to remove heat from the engine, and it does this for the most part by sending the heated anti-freeze to the radiator located in the front of the car. The position of the radiator allows outside air to blow across the radiator thus cooling the anti-freeze. The anti-freeze is then sent back to the engine. Hot anti-freeze is circulated throughout the cooling system by the radiator and heater hoses. Think of the heater core as a small radiator located inside the dashboard of your vehicle. hope this helps, have a nice day.

My 08 Impala heater blows hot air when moving and cold air when stopped. Any suggestions???


My 2005 impala had the same problem. Here's the answer. The heater core is plugging up. When you sit idling, the fluid movement is slow, therefore the junk settles in the heater core, still allowing enough fluid to get through to heat. When you drive it, the fluid movement is much faster, therefore sending the junk into the heater core, plugging it up. To check for this problem: Get engine temp up to normal, feel both heater hoses. If one is hot and the other one is cooler, fluid is not passing through. Take off both heater hoses at the top of the engine, blow out fluid with low pressure.(5 or 10 lbs.) Fill both hoses with the right radiator flush. (Some engines are aluminum) Let stand for 4 hours. Flush with new antifreeze. (I used a garden sprayer) Stick the sprayer end in the heater hose and tape tight. My vent temp WAS 100 degrees. After fix was 152!!

When you bypass the heater core the path for the water to go through the core is gone. Correct?, you have connected to engine water line out to the engine water input? thus bypassing the heater core........


No, you just won't have water flow through the heater core, Coolant flows through the engine through the lower radiator hose as the water pump sucks it out of the radiator and pushes it through the engine. It then flows out the top radiator hose when the thermostat opens. It then flows into the radiator to cool off.

Is your heater core leaking?

Pontiac grand am 1994 water comes out overflow


First question: why was the heater core replaced. Was it leaking water inside the car? Or was it replaced due to no heat inside the car. If it was replaced due to no heat inside the car, the shop you had taken it to shouldn't have replaced the heater core until they conducted tests of why there was no heat even if the customer insists on replacing the heater core. The reason why I'm asking is there's a possibility of the head gasket was leaking causing the poor circulation of the water to the heater core. If so, you may have replaced the heater core for no reason and most likely cost you a bunch of money. I live by this rule in our shop: DON'T JUST THROW PARTS AT THE CAR! You 'll end up spending way more money than you needed to.
