I have it in an Ideal spot to do so
It is a 1985 Jaguar XJ6, and it has sat for about a year.. needs Oil change too
Could the %26quot;Old Oil%26quot; possibly cause Overheating?
And can i just take the Upper hose off, and Flush it that way, letting it run %26quot;Cold%26quot; for 10 minutes (Not Engine running, engine off.. but Water run through it while its off, flushing through Block and everything?)
Thanks!
Would it be advisable to flush the radiator on my car for 5 or 10 minutes and re-fill with new Antifreeze?
Your Answer:
Old oil has nothing to do with overheating.
As for the general radiator flush procedure, WITH A COOL ENGINE, you'd typically take off the lower radiator hose, or some radiators have a petcock which is like a small nut or screw that will drain the radiator.
Once it's drained, you want to flush it - and the best idea is to use DISTILLED WATER. The reasoning here is because distilled water is free of the impurities found in normal tap water so it greatly slows the formation of rust and deposits, and will help your antifreeze stay cleaner longer.
Basically, fill the radiator with distilled water, then start the car and turn the heater on max. This will circulate the coolant through the engine and the heater core. Let the engine run until the thermostat opens, which you should be able to determine by placing (carefully! it may be hot) your hand on the upper rad. hose and kinda squishing it until you feel coolant start to flow. Once the t-stat opens, shut the car off. (again, CAREFULLY) drain the radiator once again. Now repeat the process of flushing as many times as it takes until you have clean, clear water coming out.
Then premix your 50% antifreeze and 50% water (or if you're using a store-bought that already comes pre-mixed 50/50) and fill it up. Top off as necessary.
Again, that is a general, basic procedure, but hopefully that gets you in the right direction.

no the water has to circulate and then u open the bottom hose or drain valve which is on the bottom of the radiator. let the water run thru the system thoroughly.
replace the oil ASAP, it's the lifeblood of the engine.
chances are the thermostat may be stuck. buy a new one or drop it in boiling water to see if it opens.
There is no %26quot;ideal%26quot; spot to drain a radiator. It is illegal to drain antifreeze straight unto the ground because it is a poison.
yes i would advise you to flush it but not through the top hose. take the bottom hose off and back flush it. i believe i would be changing the oil and filter too.
You can't flush the system cold that way because the thermostat will be closed. You could remove the thermostat while flushing it.
I like wayne's answer.
The only change is if you've flushed with water, there is water in the system. So you shouldn't fill with 50/50. You should lookup the coolant capacity in the manual, and put in that much coolant, and the remainder with water, to achieve 50/50.
