Transmission Coolers FAQs

Question No. 1
What size transmission oil cooler do I need for my vehicle?
The correct application for any vehicle depends on a number of variables such as the type of vehicle, if there is a load the vehicle will be expected to pull of carry and the climate and terrain the vehicle will be operating in. Always consult your Davies, Craig catalogue for the correct application.

Question No. 2
Where should I mount my Davies, Craig transmission cooler?
For some vehicles customised mounting brackets are provided in the kits ie. Ford EF Falcon, EA to ED Falcon, Commodore VN to VS.All other applications will use the universal mounting kit. Maximum efficiency is achieved when the cooler is mounted to the condenser or radiator to receive the coolest air and the maximum amount of ram air as well as fan air. This is usually directly in front of the radiator or condenser. Consult your Davies, Craig selection guide.

Question No.3
What position should I mount my transmission cooler in reference to the hose connections?
The Davies, Craig cooler may be mounted with the hose connections in any direction as long as they do not cause the hose to bend too much. Our recommendation is a minimum bend radius of 75mm.

Question No. 4
How much cooling can be expected with a Davies, Craig transmission cooler?
The amount of cooling depends on the vehicle, cooler size, type of cooler, mounting location and ambient air temperature. Most transmission coolers, when properly selected and installed will achieve at least 10°C to 30°C drop in fluid temperature with a 20°C drop being average. Every 10°C drop in temperature can double oil and equipment life.

Question No.5
What position should I mount my transmission cooler in reference to the hose connections?
The Davies, Craig cooler may be mounted with the hose connections in any direction as long as they do not cause the hose to bend too much. Our recommendation is a minimum bend radius of 75mm.

Question No. 6
How much cooling can be expected with a Davies, Craig transmission cooler?
The amount of cooling depends on the vehicle, cooler size, type of cooler, mounting location and ambient air temperature. Most transmission coolers, when properly selected and installed will achieve at least 10°C to 30°C drop in fluid temperature with a 20°C drop being average. Every 10°C drop in temperature can double oil and equipment life.

Question No. 7
Do I need a Tranmission Oil Cooler when towing?
We always recommend adding a transmission oil cooler when using the vehicle for towing. You can either use our oil cooler in series with the factory fitted cooler or by-pass the factory cooler and use ours solely. We have come across many reports of users having problems with factory fitted oil cooler built into the radiators failing and causing water to leak into the transmission and vice versa causing transmission failures therefore a lot of customers are by-passing the factory cooler and relying solely on our coolers to do the job.

Queston No. 8
In the selection guide for the transmission coolers, cooler part number 680 is recommended for the EA Falcon. I havent been able to find this part on the website thou, has it been replaced
by another part?
We no longer make this specific oil cooler for the EA Falcon. We recommend you use either of the Universal fit type. Part# 676 for 4 cylinder engines, part# 677 for 6 cylinder engines or part# 678 for 8 cylinder engines or any car used for towing. 
 

Queston No. 9
Is it possible to use Davis Craig transmission oil cooler to cool engine oil ?
Obviously engine all has varying amount of viscosity depending on the oil rating. In general engine oil is a lot more viscous than transmission fluid and therefore a transmission oil cooler is not recommended for cooling engine oil. The main reason for this is that the pipes in a transmission cooler are narrower than in an engine oil cooler and the viscosity of the engine oil will cause a greater resistance in the cooler and build up more pressure making the transmission cooler inefficient.
