If it's the one in the engine bay you talking about, there is one that connects to the heater tap on joint to the heater hose.
A heater hose (rubber) or pipe (steel).
You can get a heater that magnetically sticks to the pan and warms the engine. You can get a heater that connects to the heater hose and circulates warm engine coolant. You can also get a block heater that replaces a freeze plug. You have to decide which works best for you.
Hook the garden hose to the ~1' long pig tail coming off of the aft side of the engine block. Its typically a yellow hose with a plastic screw on cap.
Install block heater in lower rad hose .
IF there is a block heater (Only some models had block heaters) you will see the electrical plug wound up somewhere under the hood. Follow that wire back to where the block heater goes into the block. If your Saturn doesn't have a block heater, and you want one, there are several options. You can purchase a block heater that replaces the engine freeze plug. That requires installation by a qualified mechanic since the old freeze plug must be removed to use that style block heater. You can purchase an engine heater that fits inline with the coolant system. That just requires cutting a hose and splicing in the engine heater. You can purchase an engine heater that sticks magnetically to the engine while in use. Be careful with that model since you should remove it if it's hanging down from the bottom; it could become a hazard when you're driving.
There are several types but generally the best are either the in-line heater hose style or the freeze plug style. If you use the in-line heater hose style, just cut the heater hose, put the block heater in place then make sure the heater control is left on at night. If you use the freeze plug style you'll need to remove an existing freeze plug and put the block heater in it's place. The magnetic style block heaters are not recommended. They seem like a good idea but they're more trouble than they're worth.
Find top hose on the radiator. Follow the hose to the engine block. Where the hose connects to the engine block, the thermo is right there.
Just un hook the hose's from heater core and put a piece of pipe in them or something and hook them together.
No. The top hose goes to the engine. The bottom hose feeds from the engine to the heater core back to the radiator.
You can install a circulating block heater in your 2001 VW Beetle on the bottom radiator hose. The installation is quite simple.
