Hearing Very Loud Running Of Fluids After I Turn The Car Off..Help?

[social]

Hey guys, after driving my car for about 30mins+ i turn it off and its a loud rumbling running fluid sound, trying to figure out what it could be cheers

yea it overflowed cos i toppd t up today,but is it dangerous or bad for the einge or anything?

[jatsvl]

maybe there is air in your cooling system,
maybe those in the vn section could help more.

did you bleed the system for air locks???
if you didnt you might want to asap, cracks heads not doing it


jatsvl i believe he just bought a vl, through the sale section

[social]

nah i just bought this vl lol, its just no put up yet

The car makes a like running fluids sound and shudders for about 20 secs then calms down, what do u mean by bleeding the system? i didnt empty it in the first place..

Also, i dnt have coolant in there, is it a must have?

[jatsvl]

you really should have coolant in the rb30,
bleeding the cooling system gets rid of the air pockets, you said you didn't drain the system anyway but if you put water in the radiator to top it up the head level is still as low as the radiator was, hence bleed the system so there is only fluid not air.
if you are not sure how to do it do a search it has been covered alot.

does the car shudder? or the coolant tank?

was the radiator low aswel??

with a vl you have to bleed the cooling system if you drain it all or if the radiator gets too low
being a alloy head the head is prone to cracking if you get it too hot,
if you let air in the system this will heat the air and crack the head.
repair cost is ruffly $1300, so not a cheap fix

make sure the radiator is full, over flow is full and bleed the system.
ill find a thread on bleeding it for yah in a sec

how to bleed

TO BLEED: (vl's need to be bled because the highest water jacket is above the highest part of the radiator)
18. undo the bleed bolt near the coolant temp sensor
17. remove the hose going from the filler neck to the expansion tank at the expansion tank end, hold it higher than the bolt hole and using a small funnel, fill until coolant runs out of the bleed bolt hole
18. reinstall the bolt
19. remove the bleed bolt on the plenum
20. fill till coolant comes out as above
21. reinstall the bleed bolt and hose and fill the expansion tank to an inch over maximum
22. start and run the engine until its at operating temperature. check for leaks
23. once cooled the level in the expansion tank should be on the maximum mark


doing this will make it run cooler obviously and prevent corrosion. if the system isn't bled properly the air trapped inside will create hotspots and blow the headgasket. its very important this is done right and re done on occaision just to be safe. i do mine every few weeks. another thing to note is aftermarket thermostats run hotter than genuine ones. our temp guage used to sit on 1-2 bars (genuine thermostat) now it sits just under half and warms up a lot quicker (dayco thermostat) we'll see how it goes i may put a genuine one back in cos i only found this out after actually doing it

some good pictures though this thread, if you still are lost where there at just ask, ive got over 2000 pictures of my car over its build and quite a few of the manifold appart and together
Bleeding VL Radiator - URGENT!!!

[harry3]

if the 2 bleeded bolts havent been undone for a long time they may be frozen by corrosion and can shear off with heavy pressure from spanner, some advise removing the hose high up on manifold instead

another way is to undo bolth bolts, and force water into radiator cap hole with garden hose

coat bleeder bolts with grease before replacing

[harry3]

if the car has factory air cond these noises are normal due to the air cond fluid equalising itself
