Radiator flush

[JH32]

I have to flush the radiator on my car as I think it's looking a bit gunky.

Would it be better to get it properly done by a professional so they can give it a high pressure clean, or should I just drain it and stick the hose in the top and do it myself?

Cheers,

James.

is there some kind of solution that can be placed through the coolant system to clean it out?

hey jimi dont spoze u have a high powered water cleaner? that could be useful

[JH32]

Like a high pressure hose?

Nah I don't have one. Maybe I could just turn the tap on full bore on the garden hose

JiMiH, after you drain the water out of you radiator/cooling system, disconnect one of the cooling hoses and run some water through it in a backwards motion, (opposite to the way the coolant usually travels through the hoses) until the water becomes clear

[JH32]

So it's ok to use the normal garden hose?

Cheers!

certainly can. Better off using garden hose its it is the right amount of pressure and not too much.

remove radiator cap

drain fluid in radiator

drain fluid in overflow bottle

remove heater hoses. flush through with water until it becomes clear. replace with new coolant

start car with radiator cap off and heater on. run un to operating temp (this removes air bubbles) seal everything back up and your away!

you mean the thermostat...

theres limited 'testing' you can do so youre better off leaving it alone. its a bit of a hassle to get it off/on as well

i'm late, but i've been away. there is a product called "mukowt", or similar. i bought it from repco. you have to drop all your coolant,put this crud in with new water, drive the car for a week with it in and then drop this out, flush through with fresh water and re-fill with new coolant and water. this is the best way, as you can end up with trouble (big trouble, i've been there) from mixing different types of coolant together.... i think "mukowt" is made by "tectaloy". the problem with just jammin the hose in the system is it doesn't get all the old coolant out and when you put your new stuff in ... it gets to mix with it. if it's the same basic type of coolant ... no wuckers ... if it's not, like ones organic coolant and the others synthetic/mineral (whatever) ... look out. the reaction i got f****ed, my brand new radiator in 4 weeks.

ITS A BIG JOB, U DONT DO IT RITE AND UR WATER WILL GO RUSTY, FIRST OF ALL U NEED TO USE NISSAN COOLANT, CALL A RADIATOR SPECIALIST AND SEE HOW MUCH THEY WILL CHARGE U

IT LOOKS EASY, BUT U HAVE TO MAKE SURE U DONT PUT 2 MUCH COOLANT IN OR VICE VERSA 2 MUCH WATER.ETC
