Hey all.

I'm thinking about getting a new radiator and I have been wondering what bigger ones fit. It's a ke70 with a 4k, it's only my daily but I want too make sure the old girl stays cool on these kinda hot days.

Any ideas?

whats wrong with your current one?

She got a little warm the other day is all but yeah just wanna be sure really is all. I had coolant she just got slot hotter than normal

Take it to a radiator shop and get it reversed flushed.

Can be done DIY but, unless you have the right tools, you wouldn't get it totally clean.

 

If you get really worried about it getting hot and overheating the interior heater works wonders as a secondary radiator.

 

 

As a side note, my dad use to lug a loaded trailer up and down hills in his old '55, it'd get a little past the half mark on a hot day.

yeah mate pretty much what towe01 said.

 

first step is to take the radiator out, turn it up side down flush it out with the hose (fill it up with water, then let it gush out)

 

do this upside down, right way up, on the side. do it a few times and make sure all the crap is out.

 

then shove the hose into your engine, give it a good flush.

 

take out your thermostat, drop it into a cup of boiling water make sure its opening fully.

 

then put it all back together with some coolant.

 

currently you would have spent $0 (cept the coolant)

 

make sure all the air is out of your cooling system (start it up from cold with the radiator cap off, make sure its parked on flat, or uphill..NOT downhill)

 

then see how it goes.

 

your looking at like 300 bucks for a ke70 radiator brand new, since they are completely metal. (you may be able to find an ebay bargain). and 300bucks is alot of money to spend on something you may not need. generally (from my experience) unless a radiator has a hole in it, or ALL the fins are bent/destroyed, its still good to use.

 

if it still gets hot, take it to get cleaned at a radiator shop, they do funky things to them and get even more crap out. prolly 60bucks or so.

think I will try the above ideas before I replace it if it's gonna be that much for a new one.

VN through VR/VS'ish commonwhore rad can be used pretty easy in a K powered rolla. Have a look in my "Tar" project thread for some pics. :wink:

I'm with dave, it's unlikely that you need to spend 300 bucks on a new radiator.

 

For 90 bucks, I had a radiator shop pull the tanks off, clean the core out completely, resolder the tanks on, pressure test and paint.

 

If it still gets hot then your issue lies elsewhere is my bet.

Another good trick, If she's getting hot, Pull the choke to make it run rich, that works wonders too.

and ill bet its a faulty temp sensor or gauge!

why not go to the wreckers and get and old vs/vn radiator for 20 bucks or so and wash it out urself? i done that on my ke20 and worked good.

I was thinking about the vn radiator but I'm a little busy this week due too a baby arriving today but I think I'll try a vn one

why not have a thermo fan hooked up to a switch? notice your temp going up a little bit, flick the thermo on and keep it cool.

If you're going to use a thermo fan, you might as well use a thermo switch and let it take care of itself, the wiring is no harder and it removes the need to manually turn the fan on and off yourself (because there will be a time that you forget and by the time you realise it you've cooked the engine).

mine was actually a datto 1200 not a ke20,, but it seemed to fit in easy. all i done to hold it in was cable tie it in. was only on a trash car tho.
