I have a leak on the right side of the engine,its from a metal pipe connected to a hose that connects to the radiator,what is those parts called? is this an easy fix?

Is it all one piece, the outlet pipe and the t-stat housing? The gasket goes on the bottom of the housing where it mates to the engine. If the coolant is leaking from the bottom of the housing, that would require a new gasket. If coolant is leaking where the radiator hose connects to the pipe, have you tried tightening the hose clamp? If the outlet pipe and housing are separate, there may be an O-ring seal between them. You may want to pull off the radiator hose and check if the pipe is so badly corroded and rusted that it cannot seal anymore, or may have a hole in it, especially if it is thin metal.
If you have the V6 (2.5L) engine, be advised: it's a wearing task. Just getting to the radiator drain plug can be a problem without a 3/8 inch drive ratchet, a 3 inch extension, a universal joint. and a 19 mm socket. The drain plug is on the passenger side of the radiator on the engine side. The 19mm socket will fit over the drain plug to turn it open. The coolant plumbing on this engine is the craziest I have ever seen. The thermostat is on the rear face of the engine (where the radiator hoses connect), but not on the upper hose where it connects to the upright pipe with the radiator cap on it, it is on the lower hose connection. Pull that hose off the housing, and remove the three bolts holding the thermostat housing to the engine. It will help if you first remove the big air inlet hose from the air filter housing to the throttle body. I wouldn't even bother with the thermostat till you have found the leak. Is any coolant leaking from the front of the engine, dripping off the bottom behind the crank pulley? That would be a water pump problem or SEAL, an o-ring on the back of the water pump. Now get on the driver's side and look around on the rear of engine nearest the firewall where engine and transaxle mate. Look down there for signs of coolant coming from rear of engine and running down onto the transaxle case. There is a metal pipe laying in the valley below the lower intake manifold, connecting the water pump at the front and the rear housing where the radiator hoses and heater hoses connect. This metal pipe uses an o-ring for a seal into the water pump, and the same size o-ring to connect to the rear housing. If one of those o-rings is leaking, you have a big problem getting to it.. I took the rear housing off once (never again!), Now I'm taking the water pump off to fix a leak. The water pump is run by the timing belt, so the front of engine needs to be stripped down, and the timing belt removed to take off the water pump. That metal pipe is held in place by a bracket with one bolt on the rear of engine; it may require taking the lower intake off (again) to get to both of those pesky o-rings. I hope you don't have the same problem, and if you have the 4 cylinder engine, the thermostat is a snap to replace, plus you don't have that crazy plumbing problem.
try the scrapyard and look at one in their ,or ask a local owner that is just parking up in a supermarket and look at theirs .lots of different ways to overcome this problem but if the pipe has beeen disconnected its because the heater matrix is no doubt leaking
Follow the lower hose from the radiator to the metal pipe that runs under the engine and connects to the back side of the engine to the water pump housing. Remove that metal pipe from the water pump housing and the t-stat will be right there.
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.
Make sure you don not run low on transmission fluid in your transmission. Low transmission fluid will cost you a new transmission. You have the transmission line that connects to the upper passenger side or the radiator and the lower passenger side of the radiator. Determine which line has gone bad and you can buy a rubber transmission line hose at most Auto Parts store like Parts Source. Cut off out the section with a pipe cutter that has corroded through and replace with the transmission hose. Make sure you tell them it's a transmission line hose your looking for and don't use any other hose and double clamp with a compression clamps at ether end. If it's the connection at the radiator that has gone bad, replace that end and do that same as you would to sectioning off the the corroded line and try not to have more then 3 inches of repaired section. What ever you do, do not add any stop leak, this will create problems with the shift solenoids and check valves in your valve body in the transmission causing a transmission replacement soon after adding. Good luck and keep me posted.
Hello **** B. First double check the hose connection for the leak, it can drain to another connection & appear to leak there. Second, yes there is a gasket on the pipe connection to the block. To replace the gasket, park the car in a location for least 5 to 6 hours to cool down mabe longer. Have the gasket replacement, a tube of gasket sealant, 2 gallons of antifreeze, a drain bucket, and a very large rag or rags. Remove the hose, catch the fluid in bucket, remove the pipe, clean the old gasket area, apply gasket sealent, attache gasket, mount the pipe, tighten all mounting bolts a 1/2 to 3/4 turn each until torqued downed evenly, and attache hose. Fill reservoir, with radiator cap off, start engine and add coolant to radiator until full and you see fluid flowing. Apply cap & check for leaks. Easy???????? Good Luck.
there is no metal pipe goes from radiator to the engine. however, the is a upper water hose, and the lower water hose.
radiator can't be connected to teh engine via metal. it will break whent eh engine starts.(vibration).
pleae the rate the answer if this is the correct answer
thank you
