Coolant Return piping from Heater, Oil Cooler and Tank
EDIT: Since this post and installing the engine, I have modified the coolant pipe. Notice the long 90 degree section. Via a hose, it connects to the bottom of the Coolant Expansion Tank. Well, that section of metal pipe and hose was directly over the top end of the right side motor mount bracket and bolt. It was very difficult to access and remove the mount bolt. So, I moved the pipe near the end and angled it back and down toward he bottom of the Expansion tank (sorry, no pics). The mod was made in June, 2017.
Markd89, thanks for the comments and input. I'm leaning toward your suggestion of a continuous running fan.
Here are some photos of the Return Coolant Piping from the Heater, Oil Cooler and the Coolant tank.
This issue was discussed on page 18 at post #266. But, I will repost some of those photos again here.
The issue that I'm addressing here is the "directional angle" of the heater Return line at the engine. With the engine sitting in the Jetta that pipe pointed toward the firewall (in the Van that would be to the left side). I need it to point toward the front of the vehicle and slightly to the right (looking from rear of vehicle)
All Comments are at the top of the PHOTOs.
This photo shows the OE location of the pipe there at the back end of the engine block just below the end of the head...its black and pointing to the right and UP. You can see it there below the Turbo oil feed line.
In this shot, you can see where the top left coolant hose coming out of the Oil Cooler goes up and into the pipe .....that's return flow. The flow is to the left toward the water pump (into the T-stat housing).
Here, you can see in this close-up the short stub T return line from the Oil cooler. Notice that the other line coming from the heater has been cut-off (looks to be flush with the end of the block). That smaller black line is the oil feed for the Turbo.
This is another angle. You are looking directly into the return pipe from the Oil Cooler. See to the right where I cut off the return from the heater. Coolant flow would be IN and to the left toward the TB end of the Engine to the water pump housing on the block!
In this photo, you can see the complete coolant return pipe that involves the Heater return (top left), the Oil Cooler Return "T" pipe (center at between 6 and 7 inches) and the Round Coolant Tank return (to the right). The bottom part goes into the back of the Water Pump housing on the block.......the round rubber seal is slightly visible!
In this photo, you can see how it has been modified. The far end points to the right toward where the return heater hose is located in the Vanagon. The foreground of the photo is pointing toward the rear of the vehicle (timing belt end of the engine).
EDIT: In the pic below, see the T off to the right? Well, it is the return from the bottom of the expansion tank. In June of 2017, I cut it off and moved it to the right side of the bend at the top of the pic. It now points basically in the same direction. This gives me much needed access to the top bolt of the right side motor mount bracket which is located near the metal dip stick tube. edited on 12/28/2017
Here is another angle of the finished modification.
Here is a close-up of the modified end of the Coolant Return pipe. It will be buffed at the weld joints and painted!
Here the coolant return pipe is "sitting" in place.
Here is a similar angle as above. You can see the Starter and Clutch Slave in this photo.
These are the sort of things that slows a project to a grinding halt. But, in the end everything will fit better and, of course, look nice!
