How do I bleed the cooling system on a 1992 Isuzu Rodeo?

engine cooling not A/C cooling of humans...
fill it slowly at rad.
with the hightest hose removed at one end.
not put it back. (hose)
repeat with rad cap off. filling,,, AF. (antifreeze is AF)
get the rad full of 50% AF
cap off, start engine and stop it when the coolant starts to overflow.
if the coolant drops add some now. running.
if it overfills. good, that normal (hot AF expands pure physics)
then cap the rad.
drive around block.
come back park .
let it cool, and check cap level at rad neck
add AF to fill
then drive around block again. and check cold again.
is it now stable, its ready to rock. (drive)
if it is not , there is a problem.

if now good, put the correct level in side overfill tank.
make sure all hoses there are good.

this is an art form , no engine stated, here, just Rodeo
there are 4 engine here, in uSA. for one car.

but my answer above covers most engines.
but there are some exceptions on some...
the thermostat must have the bleed (jiggle pin,etc) on the up hill side. on all engines. or it will be hard to bleed.

just dont drive a long ways until, the cold rad proves (cap off)
that it is really full.
then get the side tank working, with the hoses good so it
can suck back AF when cold, or it will drop each day. driven.

How do i replace the coolant in my 96 dodge caravan after i flush the system

Make sure all the drains are closed, start filling the rad and allow the coolant time to drain down, then fill again. Keep filling the rad unit it no longer drains down, just make sure to stop filling it when the level in the rad is just barely visible when looking down inside it. Now fill the overflow bottle to the lowest level mark. Start the car and turn you heater on to full heat. Let it warm up to proper temp, may/may not need to put more in rad. Keep an eye on the level in the rad it will expand and may overflow, if it looks like it will overflow use yout tester to remove some fluid. Once you see the coolant flowing throug the rad wait a few minutes, then put the rad cap on. Let it run a few more minutes to get the rest of the air out, then drive like normal. Check the fluid level in the overflow bottle (engine cold) over the next few days fill to proper level as needed.

Radiator cap

old post.
yes the RAD cap
car has 3 diff, engines. so. can;t be specific.
what year 2008+?
ok, allcars,
you fill it to get the block full and the Radiator to the top
the side tank , only major function is for the cool down.
during cool down it allows the RAD to **** back coolant, as she cools.
it also prevents green AF on the pavement as engine gets hot.
that second part is for pollution rules.

the car has a FSM, manual, in there are rules for your car and you opted engine.
The plumbing on all cars , all engines, very by same.
FWD, RWD, too.
as does some other options. (block eaters?)

if you read service books
it tells you, to burp the engine and rad.
I run the engine for 2 heat cycles, and then when cool
i check that the rad fluid is full to the top of the RAD.
Here is what id do , (assumes thermostat not pulled)
I fill the rad with 50% AF.
i run motor util it starts to expand, if the level drops as i run motor
I add more, then when the AF starts to leak out, I cap it off.
then fill the side tank (expanson tank) 1/2
i watch the tank for 2 days. to get out all air. in the system.
if my dash coolant gauge, shows odd readings, at any time.
say it is not constant rise to 200f , I know I have air in the system.
If true, i use burping techniques,, ASK !
All mech's know about this....
also putting a thermostat in wrong will trap air.
the stat as a bleed hole that MUST be up hill side.
or will trap air.

now I answered for you and 1billion other water cooled engine owners.

Car overheated, we filled all fluids, replaced wires and plugs and acabin there is no heat

Did you re-fill radiator when engine cool, rad cap off and heater turned on? If not, do it with heater turned on and allow engine to get up to operating temperature and rad fan comes on once or twice, indicating coolant returning to rad for cooling . Keep an eye on coolant level and top up as required, then after fan has come on and off a couple of times, put your rad cap on properly and top up coolant return bottle to proper level. This should bleed out the air and get heater working properly again.

1996 Legacy Overheating It has coolant and both fans are working. Overheats after about 10 min of driving. Checked oil was a little low put 1 liter in. Radiator has pressure, opened when hot and coolant...

Costs nothing to try this, just in case coolant level was low when or after bottle changed, and you got an airlock. Start car when cold, rad cap off and heater on. Now let in run until it comes up to normal operating temperatures and rad fan(s) kick on and off, 2 or 3 times, and add coolant to proper level in rad if it goes down during process. Then after that, put rad cap back on, fill coolant return bottle to proper level and try it. Quite often when re-filling an engine cooling system, people forget to turn on heater to get coolant circulating through the heater core.

Cooling system problem

well it might overheat because air got into system, replace the thermostant and then fill system, run van keepin an eye on the temp, it will start to run hot because coolant has not filled the motor just the radiator, when it starts running hot shut it down, wait 3 minutes and start, now this is done with cap off,after restart coolant should get sucked in get filling radiator as needed,may get messy but got to bleed cooling system. hope thius helps.

Vehicle needs to purge all the air form the radiator. Jeep Grand

Start vehicle when cold. remove rad cap, start engine & put heater on (not defrost) and let it run for a while & top up rad as coolant goes down, to about an inch or 2 from top of rad. If you have electric rad fans, watch temperature gauge and around normal operating temperature or slightly above, they should come on for a minute or 2 then shut off. If not electric fans, just watch in top of rad for increased flow through rad, indicating thermostat has opened & coolant is circulating. Rev engine slightly every once in a while for 5 or 10 seconds just to help increase flow etc to help assist bleeding air out faster. Watch for increased flow in rad, 2 or 3 times at least, or listen for fan to go on & off 2 or 3 times before putting rad cap back on. As your doing this, keep topping up rad if it needs it. Make sure rad cap on all the way, check coolant return bottle level & add to mark if required, and you should be good to go. One of the things people forget to do the most, is to turn heater on while doing this, and that is usually what causes a lot of airlocks in the system, so don't forget that step.

Coolant leaks

That's probably coming out of your coolant return bottle. With rad cap off & engine cool, look at your level in the rad, if necessary top it up to an inch or so from top. Start engine, turn heater(not defrost) on and let it run until up to normal operating temperature. Keep an eye on temperature gauge & rad level. When it's at normal, watch for good flow going through rad when thermostat opens. after flow slows down,(thermostat closes) top it up if needed. If you watch 2 or 3 times for flow, and gauge doesn't go over normal, then put cap back on, then fill bottle only to mark for warm or hot engine, with coolant. If gauge goes up over normal from there, replace thermostat, and I'd get a new rad cap too. If that has electric cooling fan, make sure it comes on shortly after you see thermostat open & coolant flowing through rad.
