Leak in radiator reservoir and change spark plugs and wires

I recently discovered a leak in the antifreeze reservoir. Is this a problem if I check the radiator each week for proper level? Also, how do you change the spark plugs and wires on a 1991 Lincoln Mark VII LSC? Are special tools needed? I will not be doing this, my brother-in-law is so I need to have everything for him. Thank you.

The plug change I already answered. hope that was enough...although a thought I just had was that some plugs have to be removed thru the wheel arches after removing the tire and inner protective shroud. I cant remember for your vehicle if thats one of the methods, you'll soon find out when u attempt removal of the old plugs.
BTW if you cant seem to get to one, do all the wires and other plugs and get a local mechanic to do the hard one. Dont be tempted to leave one crappy old plug in there you;ll undoubtedly get a large bite in the *** later on for that believe me. I aint done that but I have had to repair vehicles that had that old plug stuck in the rear of a V8 misfiring like hell.......
The coolant leak is not a big problem in the reservoir but if you can see it and/or get the reservoir off easily, I have fixed these a few times by drilling the leak hole round, then screwing in a self-tapping screw covered liberally in gasket ATV or regular silicone (bathroom mirror sealer) the reservoir need to be empty or below the leak line and dry so that the ATV/silicone will bond. A hot glue gun is also an ideal repair tool.
The problem with not repairing the leak is that the coolant pressure will not be right causing a change in the boiling point of the coolant, lowering the boiling point and reducing the cooling effectiveness of the coolant. This is a bit extreme for a small drip but under pressure that can turn out to be a real hisser....anyhow I probably overkilled this problem lol...hope u get it all done ok :)

you don't have to worry about a special tool if you are replacing the wires but you will need a 5/8 socket with a rubber boot and an extension and maybe a swival to remove the plugs if there is an auto zone near by they will print you out a diagram for free

Acura rl 3.5 antifreeze pushed out reservoir cap. no white smoke out back of pipe when starting


Blows out? Probably a head gasket. they don't always blow white smoke. Parts store sell a kit to check exhaust in the reservoir or radiator. Best bet. If it blows out, Fill it with water, leave the cap off. Start it and put your hand over the reservoir opening. You feel any pressure being cold. Head gasket.

I have a hino truck 268 and recently the light level antifreeze start show ,the level is OK in the reservoir tank but inside the radiator is low what cause of this


you could have a leak in the system. get the system pressure tested and checked for leaks. if no leaks are found it could be burning coolant.

If you are loosing coolant and cant find any leaks check your oil level. If oil level is rising.you have blown a head gasket or cracked a head. Common when an engine over heats badly.

How do I locate a leak that lets antifreeze and oil mix inside the oil pan?


Most likely a head gasket. The coolant is forced into the oil chambers and mixes. This too leaks into the exhaust gases and burns off as you describe. You usually get oil in the coolant reservoir. This can be checked with a test strip available at automotive supply store. It measures the acidity in the coolant.

There should be a fluid capacity chart in your owners manual. You can also just go ahead and fill the reservoir to the proper level with coolant and keep an eye on it. If after a week you notice it low again and you still can't find the spot where the leak is, I'd try using some good old stop leak. Also, take a look at your oil to see if it has coolant in it. If so, it will have a brownish grey sludge gathering around the oil filler cap. If that's where your coolant is leaking, you may have a leaking head gasket and that would explain why you can't find a leak elsewhere..

How to change the radiator


TO CHANGE RADIATOR FIRST YOU TURN OFF RADIO FIRST TO KEEP FROM LOSING RADIO CODE.DISCONNECT NEGATIVE BATTERY CABLE.RAISE FRONT OF VECHICLE SUPPORT ON JACK STANDS.REMOVE THE LOWER SPLASH SHIELDS.NOW YOU NEED TO DRAIN THE COOLING SYSTEM.CATCH COOLANT IN A LARGE DRAIN PAN.REUSE COOLANT IF ITS FAIRLY NEW.IF COOLANT VERY OLD CHANGE IT.PUT OLD COOLANT IN SOME EMPTY CONTAINER TAKE TO A GARAGE OR WHOEVER DISPOSE IT.DONT POUR ON GROUND.HARMFUL TO THE ENVIRONMENT.MOVE THE AIR INTAKE DUCT PASSES OVER THE TOP RADIATOR HOSE.NOW WHEN ALL COOLANT DRAIN OUT.LOOSEN UPPER AND LOWER RADIATOR HOSE CLAMPS.THEN DETACH THE RADIATOR HOSES FROM THE FITTINGS.IF THEY ARE STUCK GRASP EACH HOSE NEAR THE END WITH A PAIR OF ADJUSTABLE PLIERS AND TWIST IT TO BREAK THE SEAL THEN PULL IT OFF REMOVE SMALL COOLANT SURGE LINES FROM TOP OF RADIATOR THAT GOES TO THE OVER FLOW RESERVOIR..DISCONNECT COOLING FAN ELECTRICAL CONNECTOR.THEN REMOVE THE COOLING FAN.REMOVE DISCONNECT AUTOMATIC TRANSMISSION COOLER LINES GET READY TO CATCH TRANSMISSION FLUID THEN PLUG LINES. NOW UNSCREW THE FOUR BOLTS TWO ON EACH SIDE OF THE RADIATOR THAT ATTACH RADIATOR TO THE AIR CONDITIONER CONDENSOR CAREFULLY TIP TOP OF THE RADIATOR SLIGHTLY TOWARDS THE ENGINE.REMOVE THE UPPER RADIATOR SEAL AND LIFT RADIATOR FROM THE ENGINE.NOW IS THE TIME TO REPLACE THE UPPER AND LOWER RADIATOR HOSES WITH NEW ONES SINCE ALL COOLANT REMOVE I WOULD REPLACE THERMOSTAT AND RADIATOR PRESSURE CAP.NOW WHEN YOU GET READY TO INSTALL NEW RADIATOR USE SHEETS OF CARD BOARD PROTECT RADIATOR FINS AND CORES FROM DAMAGE WHILE SITTING RADIATOR BACK IN PLACE.ONCE YOU GET UPPER AND LOWER HOSES IN PLACE ALSO PLACE SMALL SURGE HOSES FROM THE OVER FLOW RESERVOIR TO RADIATOR NEW THERMOSTAT AND TRANSMISSION COOLER LINES ALL HOOK UP. START POURING ANTIFREEZE IN THE RADIATOR OR OVERFLOW RESERVOIR IF RADIATOR DONT HAVE RADIATOR CAP ON IT.POUR A FULL GALLON ANTIFREEZE AND A HALF MORE IF LONG AS THE COOLANT STAYS ON THE COLD LEVEL MARK ON OVERFLOW RESERVOIR DONT OVER FILL.IF YOU POUR ANTIFREEZE IN RADIATOR KEEP POURING ANTIFREEZE UNTIL LEVEL STOP DROPPING AND LEVEL OFF AT RADIATOR TOP.START ENGINE CHECK FOR LEAKS. LET ENGINE RUN UNTIL IT WARM UP TOP RADIATOR HOSE GET HOT.WATCH COOLANT LEVEL IN RADIATOR OR COOLANT OVERFLOW RESERVOIR WHEN THERMOSTAT OPENS COOLANT LEVEL WILL DROP.ONCE YOU HAVE ENOUGH COOLANT IN THE SYSTEM COOLANT LEVEL WILL STOP DROPPING.THEN YOU READY TO GO.LET ENGINE SIT A LITTLE WHILE CHECK COOLANT LEVEL AGAIN.COOLANT LEVEL IN THE OVER FLOW RESERVOIR SHOULD BE AT HOT MARK FOR HOT ENGINE AND WHEN ENGINE COLD COOLANT LEVEL SHOULD BE AT THE COLD MARK.IF POUR ANTIFREEZE IN THE RADIATOR COOLANT LEVEL SHOULD BE AT TOP OF RADIATOR BELOW PRESSURE CAP.

Hi Karen
The problem here could be that you may have a leak in your coolant reservoir. Especially if you can smell antifreeze (coolant) after driving it could be that some of the hoses may be plugged depending on age and when the radiator is trying to feed the fluid back into the reservoir it cant this can also impact the levels sensor.
Have the hoses checked as well as the coolant reservoir and check for fluids/moisture around the bottom of your radiator. It commonly is collecting around that area when you have a feedback issue.

Need to put antifreeze in the radiator of my dodge neon. Do I have to drain it first or is there a way to get antifreeze in it without draining it. And if I do have to drain it where is the plug?


The drain plug is at the bottom of the radiator on the passenger side. I see no reason to drain it all out unless you just want to change it. If you do our Neons take the orange radiator fluid Havoline "Dex-Cool" invented by Havoline. It has a very bad taste added to it to protect children and pets. I changed it at 74000 in my wife's 2003 Neon SXT using a 50/50 mix of Dex-Cool and distilled water to avoid any scaling residue.

Our Neons cannot use any other type as it will ruin the internals of your engine the coolant comes into contact with.
The anti freeze is to be changed at 100,000 miles. If your coolant reservoir tank (located in the engine compartment on the drivers side just under the windshield large white plastic bottle) is always filling up over time and spilling over you may need a new radiator cap.

The radiator cap lets some of the coolant out in to the reservoir tank as you drive and the coolant expands due to heat. When your radiator cools off a vacuum is created inside of your radiator at that time your radiator cap is to open it's valve and **** the coolant from the reservoir tank back into the radiator via the small hose that leads from just under your radiator cap to the reservoir tank.

Make sure the hose leading from just under your radiator cap to the reservoir tank has a tight seal at both ends as well as no leaks.

If your cap is not operating properly it will just keep letting coolant out and not letting the radiator **** it back in resulting low coolant level in the radiator.

you need to have a pressure check don on the radiator. this will pinpoint the leak if you dont see any leaks externally it could be a head gasket or a manifold gasket but the simplest thing to check is the thermostat. it may stuck in the close position and not letting you antifreeze circulate
