How do I flush the cooling system in a 2000 hyundai elantra?

There are several methods for flushing the cooling system on ALL engine cooling systems. Time honored is drain the radiator (drain ****). Fill with fresh water and run engine to operating temperature until cooling fans turn on. Drain cooling system again. Refill with 50-50 coolant. Another method is purchasing a "T" vlave (coolant flush/service kit) from Autozone, PepBoys, NAPA, O'Reilys, CarQuest, etc.). This "T" valve is installed in one of the heater hoses & attached to a garden hose. Remove the radiator cap & turn on the water supply to the garden hose. Let water run until flush water is 'clear'. Remove garden hose from T valve & refill radiator with pure coolant until the T valve drainage turns green/orange. Install T valve cap... DONE!

I have a 1997 Chevy S10 pickup that runs hot when the air conditioner is on. Does it need a new thermastat or just a radiator flush?

A radiator flush may help but be sure the cooling fan clutch is working properly. They tend to weaken and slip excessively after a lot of miles.

1998 Chevy S10 heating problem

Sounds like someone put too much radiator leak **** in it or used well water and stoped up the heater core. Take the hoses off the core and try back flushing it thru the heater core. I have found this to work sometimes....good luck.

Hi;I have a chevy s10 pickup 1996 no heat the radiator and heater core has been flushed twice.Also has a new thermostat and it wooked acouple days and now back to luke warm air any ideals?Thanks Randy

It is possible you have air bubbles in the cooling system. Loosen radiator cap or resivor cap and let idle for about 15 minutes. Tighten cap and drive and see if that helps. REMEMBER TO START THIS PROCEDURE WITH A COOL MOTOR AS THINGS WILL BE QUITE DANGEROUS DUE TO COOLING SYSTEM PRESSURE WHEN HOT.

1998 S10 heat wont work sometimes

When you say the heat doesn't work are you meaning the fan doesn't blow out hot air or just doesn't blow out any air? if it blows cold air sometimes when you have the heat on then it could be poor circulation through your radiator or a weak water pump. make sure your radiator is clean on the inside, not too corroded or nasty inside. You can buy a radiator flush thing from wal-mart or any auto parts store. See if it helps.

Flush a radiator

You don't want to do that anyway. There is a kit that goes in line to the heater core line. Live chat me and I'll explain it or you can go to your auto parts and they can explain it. Used to be a mobile mechanic and learned how to do a lot of stuff without breaking seals. If this is helpful, please post as such
