All I have done for 49 years is drain the radiator & then
refill with 50/50 or 60/40

If you do every 3 years your okey

People are obsessed with coolant & trans flushing,why?

You do not have the engine running until you have it refilled
then add as the thermostat opens & fill the degas bottle

SOURCE: how do you back flush the cooling on a 2001 osmobile sillouette mini van

Use the heater hose to back flush the cooling system, they make an adapter kit for what you are doing, it's very inexpensive, it goes in the supply line to the heater core, that is the larger of the 2 hoses.

SOURCE: How can I flush my whole coolant system

Preferable to flush as much out as possible to get rid of the old stuff and can be done at home by undoing the heater hose at the fire wall and using the garden hose to force water through until it comes out clean Dont turn hose on full blast as it will spray out over everything build up to it so it doesnt make a mess.Make sure the heater is in the on position so that water comes out the pipe you took the hose off.Either way though it will still be ok to just undo the bottom radiator hose as the majority of it will come out.

your radiator has a pecock on the bottom of it screw it out then you can run water through a hose behind it once it stops draining to get any residue out as far as the engine youll never truly get all of the old coolant out without tearing it down and putting it back together so flushing the radiator is just fine.

Recently replaced the bulb in my 2006 silverado headlight now im am getting signaled by on coming traffic even if my low beams are on


probably you were not succesfull on fitting bulb into its place correctly. once headlights designed with really low focal point tolerances even you have a bit of wrong orientation of bulb it wont illuminate ground correctly. light rays scatters around from reflector. please check bulb and place it once more.

Leak in the radiator hose lower one should i do anything else after changing the hose


1. Turn on the heater controls. Remove the bottom R/ hose entirely and then remove the top R/hose from the radiator end. (If the top hose has not been replaced previously (or recently) then replace it with a new one as well). Then flush the cooling system.

2. Reconnect the new hoses and refill with the correct spec coolant as stipulated by the manufacturer. Do not use anything other than the coolant type/mix specified by the manufacturer. Start the engine and continue to refill the radiator as the level drops. Check and re-check the coolant levels. Make sure you check the overflow reservoir and top up to the coirrect level.

3. You will need to bleed air from the cooling system because air will be trapped and the cooling system will not operate properly with air in it. If you do not know the correct procedure for doing this on your model you will need to have it done by a competent mechanic familair with your vehicle.
Failure the bleed air from the system will result in the engine overheating, due to air locks in the cooling system, and possible expensive engine damage.

Over heating 1998 cherokee


Yes - Your radiator not only needs to be flushed you could also have an inexpensive procedure done at any reputable radiator shop called "rodding out" and then heat flushed. If I remember correctly 98 Cherokees have a 4.0 in line 6 cylinder motor that has a aluminum radiator. If you remove your radiator yourself (drain detach hoses and unbolt assembly) and bring it to the radiator shop you could get this done really cheap. If you are not comfortable doing this, have them do it for a slightly higher fee. This should really help. NOTE: When adding radiator fluid from now on, use 50/50 premix or if you mix it yourself always use DISTILLED Water. This prevents corrosion buildup in your system. Good Luck!!!
