Go to a different make of radiator friend. That companies radiators that all leak is not a reputable company. Even of it's an OEM radiator. Or take it to a radiator shop and have them test, repair and re-install it. THEN you KNOW it's not going to leak.

On this one, You will need to know where the water is leaking from and oil as well. Sounds like a hose or Tstat gasket. The oil leak cud be the gasket on the oil filter.

My 1990 toyota corolla is getting hot really fast - i fill radiator up and after 5-10 min the water has evaporated - it appears to be leaking somewhere around the right side of engine (facing front of car)...


Well there are only 3 things that could have gone wrong.

1. Radiator Leak - this means the radiator has developed a hole with via corrosion of the metal parts of simply integrity failure of the plastic parts of the radiator.
2. Hose leak - this could be a hole in 1 of 2 hoses that connects the engine to the radiator. Or it can also be a leak where the hose connects to the radiator (clamp Failure).
3. Water Pump breakdown - this is where the gasket in the water pump has failed and is leaking out the water rather than pumping it.

All the problems above has different ways of diagnosing. but we can probably narrow it down.

1. if the leak is near the radiator then it could be a hose connection, hose breakage or Radiator hole.

2. if the leak is nearer the engine then check the other end of the hose and if its not there then it could only be the water pump is leaking. You can check this if there are water stains on the water pump. The water pump on a 1990 corolla is mechanical turned also by a fan belt. Look for a pulley that has a hose connected to the radiator and that would be the water pump.

My exe's 98 blazer overheated on the way home last week, replaced thermostat on the side of the road, no help. She took it to a repair shop they told her they did a CO check of the coolant and she had a...


Assuming the following;
The head gaskets were replaced properly
The Water Pump was replaced properly
The Thermostat was replaced properly

There are only a few other things to check.
1) if you you remove one of the heater hoses from the engine bib during a cold filling from the radiator - it will release trapped air until you see the coolant coming out the motor side - this works great to ensure the air is out. Hook hose back up before running.(or you could leave the hose off for a second and start it to see if water gushes out - water pump check - kinda messy though)

Remember that heater water will circulate even with the thermostat is closed.

if that does not work, then you need to ensure the top hose going to the radiator warms up indicating the thermostat is opening and hot engine water is starting to dump into the radiator.

2) the radiator more than likely is clogged and needs cleaning by a radiator shop, or replacement if it is not one that can be cleaned.

Ask your son if he remembers looking into the water ports where he took off the old water pump, sometimes of the system is not flushed at proper intervals, it will sludge up the water jackets and keep water from circulating through the motor.

one last thing (gulp) That CO check is pretty accurate - and cheap. You might want to have it checked again - because the heads should have been inspected for cracks as well as pressure checked before putting them back on - especially since the motor overheated. That alone will crack the heads beyond repair - more so than not.

Let me know if you have any other questions.

Good Luck.

Just had radiator replaced, leak has developed around housing/gasket of hose running to passenger side just to side of engine and slightly behind. My mechanic doesn't know what the part is we are looking...


is it actually on the engine? I ask because you say it is to the passenger side and just behind the engine, that makes me think it is a heater hose, the heater hoses go from the water pump to the heater core which is located on the passenger side, the difference between heater hoses and radiator hoses is the size and of course location, heater hoses are generally about 1/2 inch to 1 inch, with radiator hoses being between 1 3/4 and 3 inches

I put oil into the radiator, what do I do?


OK no big deal you are not the first and you wont be the last.
First thing have you run the engine since putting it in the radiator if not good...iF YES then it will take a little longer. but dont worrie
Take the bottom hose off the radiator and turn the heater to hot let out all the water and some oil will come out but not much as it will stick to the sides of the engine and radiator etc .
Refit bottom hose and tighten up the clamp then remove the thermostat and refit the top hose Now fill with water to 3 " from the top Now add 2 egg cups of washing up soap suds to radiator refit cap and start and run till the temp gauge gets to 1/4 up and then turn off and let it cool down for 1/2 hr and drain again ,and do the same 2 more times .
them on the 3rd drain it should be clean water and refit hose and check all clamps and wash thermostat and refit (the same way it came out)
refill with either coolant or Antifreeze and with heater still on hot start and run and all will be OK..
Let me know how you get on RON

Radiator


the upper rad hose goes from the rad to the thermostate housing. this hose is @2-21/2" the lower hose same size goes from lower rad to water pump. There is a 5/8 hose from water pump to thermostate housing called bypass hose. and you have two hoses from water pump and intake to the heater core. hope this helps if not let me know thanks
