I have a class MH (Dolphin)on a 1999 Ford F53 chassis and would like to flush the radiator and change coolant. Looks almost impossible as I can notlocate a radiator cap. I know there has to be one but the configuration with the frame members and the radiator renders it undetectable. Has anyone here had any experience with this type of situation. Thanks for your input.

on my 05' the "cap" is on the overflow bottle.
It appears the overflow bottle is pressurised.
Installing a "T" flush fitting into a heater hose and removeing the cap on the bottle should allow the system to be flushed.

On my 2000 f53 there is not a cap directly on the radiator but the cap is on a clear plastic sort of recovery "bottle".

There is no radiator cap per se. What you do have somewhere in the front engine compartment is a plastic oval like container that has a black plastic radiator like cap on the top of it. This container should have a green liquid in it - anti-freeze/water mixture. On my F-53 it is on the right hand side as you look into the engine compartment. On the actual radiator you will have to remove the bottom hose to let the fluid run out. Replace the cheap Ford hose clamps with a stainless steel screw type hose clamps.

I just flushed my '99 F-53. Had my 30.6 quarts of 50/50 ready to replace. I drained from the petcock on bottom of radiator as instructed in an aftermarket manual....and found I was only draining the radiator. I didn't have enough instructions to go further so did a good flush and replaced...not 30.6..but about 14 quarts. Even though it mixed with the old in the block it looks much cleaner...and I doubt I will worry a whole lot about it. Any idea where the thermostat is located?

Service Info from Ford Motorhome Chassis
Workshop Manual


Cooling System Draining, Filling And Bleeding

Draining
WARNING: Never remove the pressure relief cap while the engine is operating or when the cooling system is hot. Failure to follow these instructions can result in damage to the cooling system or engine or result in personal injury. To avoid having scalding hot coolant or steam blow out of the degas bottle when removing the pressure relief cap, wait until the engine has cooled, then wrap a thick cloth around the pressure relief cap and turn it slowly. Step back while the pressure is released from the cooling system. When certain all the pressure has been released, (still with a cloth) turn and remove the pressure relief cap. Failure to follow these instructions can result in personal injury.

CAUTION: The coolant must be recovered in a suitable, clean container for reuse. If the coolant is contaminated, it must be recycled or disposed of correctly and the system filled with new coolant.

CAUTION: Some vehicles cooling systems are filled with Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (green color). Others are filled with Motorcraft Premium Gold Engine Coolant VC-7-A meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same type of coolant that was drained from the system. Do not mix coolant types.

NOTE: Less than 80% of coolant capacity can be recovered with the engine in the vehicle. Dirty, rusty, or contaminated coolant requires replacement.

Place a suitable container below the radiator draincock (8115). If equipped disconnect the coolant return hose at the fluid cooler.
Remove the fill cap from the degas bottle.
Open the radiator draincock. Remove the cylinder drain plug, if equipped, to drain the coolant from the cylinder block (6010).
Filling—Bleeding


CAUTION: Engine coolant provides freeze protection, boil protection, cooling efficiency and corrosion protection to the engine and cooling components. In order to obtain these protections, the engine coolant must be maintained at the correct concentration and fluid level in the degas bottle.

When adding engine coolant, use a 50/50 mixture of engine coolant and clean, drinkable water.

To maintain the integrity of the coolant and the cooling system:

Add Motorcraft Premium Engine Coolant VC-4-A (in Oregon VC-5, in Canada CXC-10) or equivalent meeting Ford specification ESE-M97B44-A (green color), or Motorcraft Premium Gold Engine Coolant VC-7-A or equivalent meeting Ford specification WSS-M97B51-A1 (yellow color). Always fill the cooling system with the same type of coolant that was drained from the system. Do not mix coolant types.
Do not add orange-colored Motorcraft Specialty Orange Engine Coolant VC-2, or equivalent meeting WSS-M97B44-D. Mixing coolants may degrade the coolant's corrosion protection.
Do not add alcohol, methanol, brine, or any engine coolants mixed with alcohol or methanol antifreeze. These can cause engine damage from overheating or freezing.
Do not mix with recycled coolant unless it meets the requirements of Ford specifications ESE-M97B44-A or WSS-M97B51-A1. Not all coolant recycling processes meet these Ford specifications; use of such a coolant may ham the engine and cooling system components.

To fill, reverse the draining procedure.
Add the correct engine coolant mixture to the degas bottle.
Move the temperature blend selector to the full warm position.
Run the engine until it reaches operating temperature at 2,000 rpm for five minutes.
Turn off the engine and allow the cooling system to cool.
Add the correct engine coolant mixture to the degas bottle until the coolant level is between the "COOLANT FILL LEVEL" marks.
CAUTION: If the air discharge remains cool and the engine coolant temperature gauge does not move, the engine coolant level is low in the engine and must be filled. Stop the engine, allow to cool and fill the cooling system as described.

Start the engine and allow to idle until normal operating temperature is reached. Hot air should discharge from the A/C vents. The engine coolant temperature gauge should maintain a stabilized reading in the middle of the NORMAL range and the upper radiator hose should feel hot to the touch.
Repeat Steps 1-7 until the degas bottle level is OK.

The Ford Service Manual gives the following instructions in regard to flushing...

Engine and Radiator Flushing
WARNING: To avoid personal injury, do not unscrew the coolant pressure relief cap while the engine is operating or hot. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly.

Once pressure is released, remove the pressure relief cap.
Drain the cooling system. For additional information, refer to Cooling System Draining, Filling And Bleeding in this section.
Remove the water thermostat (8575).
Install the water hose connection without the water thermostat.
NOTE: Refer to the cooling system flusher manufacturer's operating instructions for specific vehicle hook-up.

Use cooling system Flush-All, Flush Kit Hardware Package and Drain Kit to flush the engine and radiator.
Use Ford Premium Cooling System Flush F1AZ-19A503-A meeting Ford specification ESR-M14P7-A with standard (green) cooling system.
Install the water thermostat. For additional information, refer to Thermostat in this section.
Backflush the heater core if necessary. For additional information, refer to Heater Core Backflushing in this section.
Fill the cooling system. For additional information, refer to Cooling System Draining, Filling And Bleeding in this section.

Okay, ... I'll bite.

How do you re-fill the radiator with anti freeze if there is no cap? Filling through the recovery bottle must require a pretty neat trick.

Having just replaced all the hoses and belt on my V10, You refill thru the recovery bottle. It's tight, but doable. The recovery bottle cap is a pressure cap.

Should be a "posi" valve on the bottom of the radiator which you can open to drain fluid out. Hook a piece of tubing on it to direct the fluid to a bucket. Take the cap off of the overflow bottle before you open the posi valve. Go easy on the valve as it is plastic.
