help please - coolant issues

rangiev8 said:

i think my air system needs "burping" as it keeps pushing the coolant out of the expansion tank and emptys itself

below is what i found on the web but before i do it i was wondering if there is anything diffrent i have to do on a 1995 p38 range rover 4.6 hse as this is more a general guide

many thanks guys for your input



step 1
Add a mixture of one-half water and one-half antifreeze to the radiator. Fill it right up to the top.
Step 2
Fill the overflow/coolant reservoir with the same 50/50 mixture.
Step 3
Leave the radiator cap off, turn the engine on and let it run until the radiator "burps": You will see the coolant level drop and may see or hear a large air bubble come to the top as the system burps.
Step 4
Keep an eye on the temperature gauge throughout this process.
Step 5
Refill the radiator to the top and coolant reservoir as needed.
Step 6
Put the radiator cap back on.
Step 7
Note that if the engine runs hot after this procedure there may have been another pocket of air that "burped." Let the engine cool down and then add more coolant to both the radiator and the coolant reservoir

When you burp a baby you pat it's back. Same with a cooling system, partial fill, start engine, slow fill and squeeze the hoses as you fill it. Just like patting the baby. BUUURRRP.

Not far off, but you need to make sure the small return pipe (runs around the front of the battery) is clear and not blocked. If it is blocked, you'll never get the air out and the coolant will blow out of the tank.

RAVE and GTR shows that you are supposed to disconnect the pipe at the radiator and remove the cap on the reservoir, and blow into the pipe to clear it before starting the process.
