Where is the radiator drain plug on a 1999 mercury villager 3.3 v-6 engine?

If there is one on the radiator it should be on the rear at the bottom of the radiator or underneath it. Sometimes it is just a plug and not a pit ****. If none is available you can loosen the bottom radiator hose and drain the radiator from there.

Why is your transmission fluid dripping from my Cadillac converter

Hi there.
Well its a hard one as it could be the hose from the radiator to gearbox leaking cause either cracked or loose connection either on radiator OR on pipe 1/2 way down above the converter
Start engine,run till you see a drip, stop engine check bottom of radiator connection pipe for leak if none check pipe down towards gearbox to find a crack.

Hi shawn, further to my previous post can you confirm that the vehicle has had a different engine installed from the original and if so what are they ? here is a diagram of the cooling syatem i think your talking about but the bigger the engine ie V6 or even a diesel, there may well be more coolant pipes,for heat exchangers etc,than are now required for a petrol engine hope this diagram helps keep me posted and include some photo's if you can

How do you put radiator in 1999 hyandai accent

1) Drain radiator by removing cap, and bottom radiator drain bung or bottom hose.
2) Remove top hose.
3) Disconnect the radiator fan's wiring and any temperature sensor wiring if fitted.
4) Remove radiator retaining clasps
5) Disconnect radiator bottom hose.
6) If fitted with an auto box, then remove automatic gearbox oil pipes (Underside)(you might wat to clasp these so they don't leak oil everywhere)
7) Remove radiator expansion bottle feed pipe from top of radiator.
8) Ease out the radiator. If the radiator fan is getting stuck or caught up, then drop the radiator back down and remove the fan first after disconnecting from the radiator body.
9) With new and old radiator placed side by side on a soft surface, change across any components from the old radiator, which didn't come with the new one. These may or may not include such things as: cap, fan retaining screws or clips, bottom radiator seating rubbers, rubber fan shrouding, temperature sensor, top and bottom rubber hoses.
10) Rebuild by reversing the above instructions. Apply silicone pipe sealant to top and bottom hose locations. Make sure you clean and/or replace any heavily corroded metal pipes which connect to the radiator. (Now is also a good opportunity to replace the thermostat to be on the safe side)

11) Fill system with a fresh 50/50 water/antifreeze mix, flush out and refill expansion bottle. Just before you refill the system, turn the interior heater setting up to maximum heat, but do not start the vehicle.
12) Top radiator up to max. Gently massage the top radiator hose to help eliminate air from the system.
13) Once filled, start the car. Pay attention to the temperature. Keep topping up the radiator as bubbles come around the system and the coolant level drops. At the point no more bubbles appear, close off the radiator with the cap. Allow the engine to reach normal operating temperature. If the weather is cold you may want to hold the engine at around 2,500 revolutions to help build heat faster. Keep it running until the radiator fan kicks in, then let it idle for a couple of minutes.
14) Stop the engine and let it cool.
15) Once cool, open the radiator cap and top up again if level is low.

16) Road-test the vehicle. After returning check again for any leaks.

Running the car for the first few days after radiator replacement, check the radiator level and expansion bottle level every day for the first two or three days. This level may drop slightly as any trapped air pockets are pushed out while running. Also, it is possible that any small leaks may begin after adding fresh anti-freeze to the system. If you begin loosing fluid over these first few days, then re-inspect your work and run a cooling system pressure test.

Need to know where the thermostadt is at. Have leakage but can't find any hoses etc leaking.

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.

Replacing thermostat

follow the bottom pipe of the radiator to the engine block. the thermostat is close to that.

a good idea would be to flush your system (get a bottle radiotor flush from a motor spares shop and follow instructions. It makes sense since you are going to be draining the system anyways and clearly you have an overheating problem so you are killing two birds with one stone

make sure the engine is off and cooled down. Hot radiator fluid is higher than boiling point.

remove the cooling system cap to ensure there is no pressure in the system.

loosen the hose clamps of the above mentioned pipe. remove pipe, from engine block and radiator.

Look for bolts on and close to where the radiator hose connects. there should be two ir three.

Loosen and remove. gently remove the housing. Be careful when removing the old thermostat and new thermostats do not come with the rubber seal you see around the thermo.

Replace with identical thermo. when replacing the housing remember to apply gasket sealant. this takes 8 to 12 hours to harden / cure.

replace the radiator hose to be one the safe side. tighten clamps, fill up radiator with anti-freeze/summer coolant and water.

You should be up and running in a day or two

How do u remove a 1991 honda accord engine

Get some boxes, bags and a sharpie marker to put things in and label them if this is your first time. Disconnect and remove battery and metal battery tray, unplug ALL wires and lines that connect to engine including AC lines that are in the way and the throttle cable and cruise control cable. Keep the plug wires hooked to your distributor so you don't lose your firing order. Drain radiator and remove it. Remove the top hose and use the long lower hose to push over the outlet where the top hose was to contain what is left in the radiator. Automatic cars will require disconnection of the transmission cooler lines from the bottom of the radiator. Open gas cap before disconnecting fuel line on intake to relieve pressure. Remove front wheels and separate bottom ball joints from lower control arms on each side, separate both outer tie rod ends from knuckle. Drain transmission fluid, pop out both axles from transmission. They can hang. Disconnect shifting linkage. Disconnect exhaust down pipe (or) disconnect tailpipe at the end of braided hose just before the catalytic converter. Mainly, get it to where the motor is just sitting there in the cradle with nothing holding it but motor mounts. Hook a chain to the pick bracket on the head near the power steering pump and to the one on the transmission. Feel free to remove the 17mm bolts in each mount as well as any brackets for these mounts that obstruct your ability to pull it up out. I have found that pulling it out on an angle with the transmission being lower helps your mood! The 4 motor mount locations are as follows: Front Center - Left - Right - Rear Center. If you are replacing this 90-91 engine with a 92-93 you will need to reuse your AC compressor and it's bracket, the down pipe and the header and the wiring harness on the engine.

Have to put fluid in the radiator and over flow tank about three times a week but don't really see any on the ground where we park. Leak stop was put in by previous owners but doesn't seem to have helped.

the fluid may be goind out the exhaust, look foe excessive moisture out of the tail pipe, if you gotta fill it so often then its going somewhere right? may be sign of a bad head gasket, jut one more thought, are you using anti freeze or just plain water, water evaps quick, and a bad cap will let pressure escape and evaporate quickly, so you will not see a leak, good luck

1995 Subaru Legacy Wagon Radiator

Hi sir, if you want to do a proper job here's how.
  1. Get radiator flush let you car Idle for a while or drive for 15 min.
  2. Let Car cool Down
  3. If no drain PLug remove the hose at the bottom this is the same pipe going into your water pump, Work gentle with it try not to damage the pipe.
  4. open your rediator cap, this will allow the water to train from radiator.
What about all the dirty water inside the engine? this is how to do a decent flush.

  • The car should be cold
  • remove the water pipe at the top of the radiator
  • take your garden hose and insert it to the rediator don't force it just hold it there.
  • Start the car let it idle, open the hose pipe.
What happens now is that the water pump pulls all the clean water trough the rediator and pushes all the dirty water out the other side.
  • when water is clear turn off water
  • kill engine
  • Tighten water hose
  • refill with good Anti freeze anti boil and top op with water
  • drive the car till hot
  • check for any leaks on the pipes you removed before
Hope this Helps
