Oil cooler & transmission cooler

Anyone know where I can get these coolers? If not, I will have to et some custom made.

Thanks
 
Quick answer is yes!
Renault model designation: CLIO RS 24V TROPHY.

These cars ran the Sadev box with a transmission cooler p/n 77 11 153 772 and a seperate oil filter p/n 77 11 153 351. This is not a air exchanger type cooler but a water cooled unit as is the engine oil cooler fitted to that car p/n 77 00 852 778.

Scott may have these items in stock and I know you guys out in HK have had stuff of him before.
He is working on more conventional air exchanger type coolers to fit in the road going V6 at the moment, so it might be worth giving him a call.
Where do you find the roads in HK to do the V6 justice? Mainland? :D
 
I'm the one from HK talking to Scott you are talking about. So does that mean the Trophy car oil coolers are not quite applicable for the road V6's?
I'll give Scott a call to see what he's got.

There are plenty of roads in HK to test out the V6, but just really tough roads.
 
Hi Klio, I just think that an air exchanger type cooler maybe better on a road car but you could probably plumb the water cooled type into your car.
What water temps / engine oil temps are you reading in the summer in HK?

Both around 100
 
100 centi?
You really want water temps of not more than 88-90C and if your oil temps go above 100C then you are cooking the oil and at least need to run synthetics.
Have you thought about fitting an electric water circ pump and reprogramming the cut-in temps on the rad and engine bay fans?

The temps are that high due to the weather and the constant traffic here. Im planning to take out the thermostat housing to keep the water running all the time. And the oil cooler will get the oil temp down.
 
Removing the thermostat is not a good idea, unless you replace it with a restrictor of the same sized orifice.
You need a restrictor as the water pump circulation is designed to work with it in the system.
Water 'wetting' additive is also a good idea.
 
where can i find a thermostat housing that starts working at a lower temp?

and what is water wetting additive?
 
Take out the thermostat from the housing and take it along to a local machine shop or garage and ask them to make a restrictor plate the same sized as the stat without the opening valve in the middle. A piece of brass plate is easiest to work with. If you have any contacts with either a CAT or GM diesel dealer then ask them, 'cos I'm sure they do it to their older units out there.
Water wetter is an additive that reduces the ph level in your coolant (please don't tell me you are running without an inhibitor in your coolant?) Red Line and STP are popular manufacturers.
I can give you a really good explanation but I'm not sure that you are upto this level of engineering or chemistry!
You can read more on the web.
Nalcool is one of the best but not available in small quantities.

Thanks for all the useful info, and yes I am not up to all this technical talk. BTW what is an inhibitor?
 
I think by inhibitor Hog may mean using 'ethylene' (anti-freeze) in your cooling system.

Ethylene glycol acts as a Summer coolant which increases the boiling point of water. Most glycol based anti-freeze liquid also contains a rust inhibitor to prevent flaking off and blockage of your radiator.
 
Maybe somone who knows the correct percentage of inhibitor for the system will post.

Sounds like you may need a little more than us here in chilly UK.
 
Inhibitor is part of the package of additives in regular anti-freeze [glycolbase]. I don't know what coolant mix Renault fill the cooling systems with for tropical climates but probably not glycol based.
Most high temperature inhibitors are high in nitrates and low in glycol content.
Nalcool recommend 50% dilution with de-ionized water.
 
My engine oil temps under heavy use are always about 115 degrees - water at 85.

Oil at 100 is average really, 120 and over is hot.

Most V6's run to hot but no-one knows as they have no oil temp sender!!!!!!!!!!!!!!!!
 
Oil temp set points - alarm led & shutdown are built in to the engine ECU.

The new Motec dash does this all beautifully and you can even have program digital graphics that can read, 'you just cooked the engine plonker'or such like!
