include two 1/4” Male NPT x 5/16” inverted flare fittings. A benefit of the transmission cooler in the radiator is the heat exchange<br />
between the radiator and the tranny cooler. The radiator brings the transmission fluid up to a safe and constant operating<br />
temperature.<br />
Our radiators are designed to fit standard GM engines. Newer blocks such as the LT1, LS1, and Vortec Gen. III blocks will require<br />
some additional features to be added to the radiator. A steam return option and smaller water inlets and outlets must be<br />
incorporated to our radiator when using it to a newer block. When ordering, please add LT1 to our part number when using a LT1<br />
block, and add LS1 to our part number when using a LS1 or Vortec Gen. III block.<br />
When using the stock <strong>Land</strong> <strong>Cruiser</strong> radiator in a Chevy application, a lower hose from a 1973 V8 Chevy pickup can be used. For<br />
the upper hose, DAYCO P/N 7672 works well. The thermostat housing must be a straight design. For a Ford engine swap, a trip<br />
to your local auto parts store will be necessary since we do not have any suggestions for these applications.<br />
FANS:<br />
On most conversions, you will be able to use a stock engine-driven fan. Most custom <strong>Land</strong> <strong>Cruiser</strong> aftermarket companies offer<br />
fan shrouds that work well with the engine-driven fan. We have seen a few engine-driven clutch fans that are too large in diameter<br />
to allow access for the radiator hoses. These can be switched out for either a flex fan or electric fan. Electric fans have become<br />
a popular addition to aid in cooling most engine swaps. Electric fans can be positioned in front or behind the radiator and offer efficient<br />
engine cooling.<br />
The Spal fans we offer are the high performance straight bladed pusher or puller fans. These 16” fans are 16.3” tall, 15.75” wide,<br />
and 3.39” deep at the fan’s motor. The fans are rated at 2360 CFM and, being that they are pre-shrouded, they are ideal for cooling<br />
larger engines. The only down side of these fans is the noise they generate that can be heard<br />
from the driver’s seat (worse on a pusher than a puller). Our fan kits come complete with the<br />
needed wiring harness which is compatible with both positive and negative ground vehicles.<br />
The 3/8” pipe thread sending unit is designed to turn the fan on at 185 degrees and off at 170<br />
degrees. The kit comes with a 40 amp relay, a fuse holder, and all other necessary hardware.<br />
In addition, our kit also includes mounting brackets for the fan to the radiator. The mounting<br />
brackets are designed for our aluminum radiators, however; we can supply you with brackets<br />
to fit our copper/brass radiators upon request. Part No. 716670 is our puller fan kit and Part<br />
No. 716671 is our pusher fan kit.<br />
TEMPERATURE BUSHING:<br />
When installing a Chevy engine, P/N 716023 will allow you to retain your stock sending unit. With this bushing you can reinstall<br />
the original <strong>Land</strong> <strong>Cruiser</strong> temperature probe back into the intake manifold or head of most Chevy blocks. This special bushing has<br />
a metric female thread for use with the original probe. The outside diameter of this bushing is 1/2” with a pipe thread. Ford engines,<br />
Chevy LT1, LT4, LS1, Vortec engines have a smaller diameter hole in the block for the sending unit. These blocks will require the<br />
bushing listed above plus an in-line temperature sensor adapters. These adapters fit on the radiator hose and allows you to retain<br />
your vehicle stock temperature sending unit and stock gauge. These units are offered in either 1-3/8” or 1-1/2” hose diameter.<br />
P/N 716673A - 1-3/8” with 1/2” sensor hole.<br />
P/N 716674 - 1-1/2” with 1/2” sensor hole.<br />
WATER PUMPS & THERMOSTATS:<br />
We offer a high performance line of water pumps that will aid in V8 cooling. Chevy engine installations have the option of either a<br />
long or short water pump. The long style water pump is most commonly used on Chevy blocks. The stock bracketry on most V6<br />
& V8s is designed to be used with a long style water pump. A short water pump will give additional radiator clearance; however,<br />
accessory brackets are sometimes hard to come by. We offer a high performance brand of water pumps and thermostats for Chevy<br />
V6 & V8 conversions.<br />
Chevy & Ford blocks can usually retain a stock serpentine belt system. They will normally provide sufficient clearance for your radiator.<br />
Be careful if you replace the water pump on a Serpentine system since they usually rotate in the opposite direction.<br />
FLOWKOOLER Pumps:<br />
P/N 25-1668 - GM short water pump (1955-91 Chevy). This water pump is 5-11/16” long.<br />
(GM short water pump has limited accessory mounting bracket options)<br />
P/N 25-1759 - GM long water pump (1955-91 Chevy). This water pump is 6-15/16” long.<br />
FLOWKOOLER Thermostats:<br />
P/N 25-1600 - 160 degree high flow thermostat<br />
P/N 25-1800 - 180 degree high flow thermostat<br />
(All brass and copper construction with a “balanced sleeve”)<br />
