Coolin' Menu

Welcome to the Coolin' Section! This section covers the engine cooling system from the coolant, water pump, hoses, radiator, thermostat and heater core. It is divided into the following:

Custom Radiator - If you have an older vehicle and swapped in a different model of engine then you will most likely find that the stock radiator doesn't work for the new engine. It will be either under-rated or have the wrong size of or location for the radiator hoses. This webpage shows how to find a radiator that will fit and how to install a junkyard radiator.

DIY Fan Shroud - So your new radiator doesn't cut the mustard for cooling and the engine still overheats at idle on hot days. Don't dispair, you may only need to add a fan shroud. Here's how to make a custom DIY fan shroud using the same techniques that custom car audio installers use to make speaker boxes.

Radiator Caps - So what is there to know about radiator caps? This webpage discusses the different types and ratings.

Coolant Overflow Tank - Tired of having your rad coolant spill on your garage floor? Add a coolant overflow tank - a few minutes wandering through the local wreckers will find several bolt-in candidates that will look great!

Thermostats - Here's a webpage dedicated to discussing what the thermostat does and how it works.

Coolant Fans - Mechanical or electric fan, which way to go? Maybe add both? How to control an electric fan? Here's a webpage that discusses everything you want to know about radiator fans.

Repairing a Leaking Rad - Your rad is leaking and money is short. Here's a webpage that shows how to repair a radiator by soldering the leaking radiator fins.

Adding a Tranny Cooler - If you have an automatic transmission, you must have a transmission cooler of some type. Normally, the transmission fluid is cooled through the radiator but did you know that the number one reason for transmission failure is overheating. Add an external transmission cooler and provide that extra safety net.

Troubleshooting Overheating - How does the cooling system actually work? This page discusses what each part of the cooling system does. You will be surprised to learn that some components work not the way you expect them to.

Troubleshooting No Heat - This is a 4 year adventure in trying to get internal passenger heat out of our used 1998 Oldsmobile Silhouette van. It is a common problem for 1997 to 2002 GM products that have the 3.4L engine. It affects Chevrolet Venture and Pontiac Montana vans also. In the winter, the van would take forever to heat up and when it did there was pitiful heat coming out of the heater.
