Okay I recently installed a new oem t-stat, new radiator, new hoses, oem rad.cap, re-man water pump, the car runs very good, but on long drives lets say hours at a time, water would go to the overflow tank making it rise near the top. Im guessing theres air bubbles in the cooling system, so how do i properly bleed the whole thing?



Tried to find answer on this forum, but i couldn't, help me out! thanks



By the way this is for a 90' vert n/a.



Thanks.!

Take the radiator cap off, when the car is cool of course, turn it on and let it run for likr 5 mins, turn the car off and put the cap back on.

thats normal, the coolant should be filled to the COLD mark, then when it gets hot it rises to the HOT mark on the overflow bottle.



if your car is running for hours and not overheating there is nothing wrong with it.



I always fill it to the top with the cap off, let it run, close the cap, then after it seems to get warmer crack the bleeder for a second.

how can you leave your car on for 5 mins without the radiator cap? when i do that with mines, it starts pushing out water little by little... im guessing i have a big problem then?

Sounds like either your thermostat isnt opening or you have exhaust getting into your colling system. Thats what just brought me down. :(



(the exhaust part not the thermostat)

Do you mean FLUSH? You don't actually BLEED the radiator.... The easiest way to FLUSH the coolant is simple.



On the Bottom of the radiator, facing the engine, there's a drain plug.



If you open the radiator cap (car off), and put a garden hose into it (w/ the water ON, of course), and undo the drain plug, it will flush out the RADIATOR.



As far as the coolant sysem goes, it's BASICALLY the same, except w/ teh car running. Start the car after you have the hose on, and hahave drained the radiator.



What this does is forces the water from the garden hose into the engine, circulating it through, and out the drain plug in the radiator.



If you drain/ flush the Radiator, first, you have less chance of circulating radiator crap into your engine.



Once you've let the engine run for a while, w/ the hose supplying "coolant" to the engine, turn off the car, THEN the hose. Keep the drain plug out until all the water drains.



After that, replug the drain, fill with coolant to where it needs to be, and you're set!

IF that procedure is safe to do, wouldn't it only work if you remove the t-stat first? and refill with distilled water, not hose water.

Whenever I do mine, like whenever I change my coolant, it just burps air bubles out of it. Doesnt over flow at all.

none of you have a bleeder on your radiator??



he stated that after he runs his car for HOURS, the overflow bottle is full, that is normal.



there is nothing wrong with his coolant system
