2000 grand Marquis radiator cap blew off


There is 14 .2 foot pounds of pressure in your cooling system .
The problem is some one didn't tighten the cap correctly you have to push down on it turn it then turn it until it locks so its two turns ..
The good news is the cooling system is likely fine its holding pressure .But if you have to add coolant you should do it through the recovery bottle that has no pressure follow the hose under the radiator cap that will lead to the recovery system storage bottle .
This will also indicate the antifreeze level on the side of the unit ..

No radiator cap how do i burp


No cap on radiator, but you do have a fill cap

Just like a radiator cap, you leave it off until the
thermostat opens & coolant flows back out the
top hose.

Replace the fill cap & put about one inch extra in
the degas or coolant recovery bottle

It should vent the air back there overnight when cool,
as it has for a the last 60 years

You provided no vehicle & this is just a chat room

Have no info about your vehicle

You have to follow the coolant hoses to a vent or no
vent or check on the internet

Refilling radiator


These cars have a closed system as the radiator gets low is sucks coolant from the recovery bottle and as the engine gets hot the expanded fluid goes to the recovery bottle when hot. the recovery bottle is to the left of the radiator You can add there at anytime it is needed. BUT DO NOT TAKE RADIATOR CAP OFF ON A HOT SYSTEM it is pressurized and you will get thermally burnt. check only cold and coolant should be with in a inch of the top. continually adding coolant means the system has a leak.

Transmission fluid in radiator & running out radiator overflow bottle


The transmission cooler is located inside the radiator on pilots, they are notorious for rotting out and leaking ATF into the radiator and vice versa. This wil quickly lead to your transmission seals failing and destroying your transmission. Happened to my wife's pilot and got Honda to split the bill

3 months ago i changed to a new radiator after going trough water bottle after water bottle.Things were fine.Now im over heating again with the problem being the pressure cap of the water bottle apparently...


There is no water bottle

All vehicles have a coolant recovery container

When the vehicle warms up ,some coolant goes
past the radiator cap into it

At night when cool, the radiator draws back what
it needs

Been that way for 50 years

That container isn't under pressure as you can see

You have to diagnose the engine overheating issue

You have a new radiator,I would assume new thermostat
& rad cap,so continue on

It is very old, so a head gasket wouldn't be a supprise

How to change a radiator on a 1996 ford taurus


  1. Step 1 Drive your Ford Taurus up a set of ramps onto a pair of jack stands, if it is a 1996 model or newer. Remove the lower splash shields. For 1986 through 1995 models, you can remove all necessary components from above.
  2. Step 2 Begin by disconnecting the negative battery terminal and draining the radiator into a transportable container. Open the plastic draincock on the lower rear of the radiator and crack the radiator cap.
  3. Step 3 Remove the overflow tube from the coolant recovery bottle and disconnect it from the radiator. On SHO model engines, remove the recovery bottle as well. Next unscrew the shroud and remove it from the retaining clips. Disconnect the wires to the fan motor, and remove the fan assembly and shroud in one piece.
  4. Step 4 Squeeze the hose clamp ends together on the radiator side, and remove the upper and lower hoses. For automatic transaxle models, use either the custom Ford disconnect tool T82L-9500-AH or two crescent wrenches to remove the transmission coolant lines.
  5. Step 5 Disconnect the radiator supports. 1986 through 1992 models will have two upper retaining screws for 3.0 liter and SHO engines. 3.8 liter engines will have two driver's side hex nuts and two passenger side screws. All other models have either the upper screws or the combination of right hand hex nuts and left hand screws.
  6. Step 6 Tilt the radiator backwards toward the engine and lift it out. Fit the new radiator into the support and replace the support screws and nuts. Reattach the hoses and wires in reverse order.
  7. Step 7 Flush the new radiator with either water or a commercial flush treatment. Connect your battery terminals and replace the coolant and let the engine idle for 5 to 10 minutes with the heater on and the radiator cap removed. Top off the coolant as necessary.
Thank you,
Lee

My 96 jetta gets hot & beeps a lot during stop & go traffic


your anti freeze is worn out and corrosion has built up and is clogging/blocking flow, solution is to drain radiator, fill with water and radiator flush (found in auto parts store) follow directions on flush bottle, change thermostat while system is empty and refill with new anti freeze mix. for more detailed help suggest a chilton's manual for your car available at auto store around$25 and guides ou through most repairs

I need to know what the part is called and how to fix it. The part is leaking hot coolant fluid, it is a ''y'' shape tubing that feels like hard plastic, black in color. It runs on the left side to the...


sounds like hoses going to heater core but they are rubber usually. But it could be the hoses for the degs bottle mounted on the passenger side inner fender.

Coolant Recovery System NOTE: When the water thermostat (8575) is closed, coolant flows through the degas tube and hose assembly from the lower intake manifold to the radiator coolant recovery reservoir (8A080) .

Trapped air in the cooling system must be removed. A pressurized radiant coolant recovery reservoir system is used which continuously separates the air from the cooling system.
  • When the water thermostat is open, coolant flows through both the small hose from the top of the radiator outlet tank and the degas tube and hose assembly from the engine to the radiator coolant recovery reservoir.
  • The radiator coolant recovery reservoir separates any trapped air from the coolant and replenishes the system through its radiator coolant recovery hose.
  • The radiator coolant recovery reservoir serves as the location for:
    • service fill.
    • coolant expansion during warm-up.
    • system pressurization from the pressure relief cap.
    • air separation during operation.
  • The radiator coolant recovery reservoir is designed to have approximately 0.5-1 liter (0.53-1.06 quarts) of air when cold to allow for coolant expansion
