Plastic Fan Blades

The concave side of the blades would face rearward.

Where I used to work someone replaced the fan backwards on the front end loader. On the loader the fan blows the air forward, away from the engine, so the concave side faces away from the engine. If you put the fan on backwards, it will still move the air, but not nearly as much.

The easy way I remember which side is concave is it's the side that's sort of like a cave.

Flip it over.

If yours is wrong so is mine, so the air is moved from the radiator back upon the engine block?

That fan is installed backwards. Concave side towards the motor, convex towards the radiator.

Won't change mine,...............if I did the temperture would never get above 160 degrees.!!!!

G`day to australia

Crank the engine slowly, have a look onto the fan and figure out what
the fan does to the air...
You want the fan to suck the air through the radiator.
(if it works like that, you have proven that your radiator is in great shape)

What kind of belt do you use?
Never saw one like that

(Im still using "original" belt from the vendors, but dont
like as they are way to stiff....)

long distance greetings

Fanbelt is inside out. Teeth should go to the pully for that style of belt. Tim

[Tom Wesenberg]

The fan belt is OK, it's just the design of the belt.

The top hose looks so short, but looks like it's connected OK. Radiator shorud still needs the screw installed.

As mentioned, the fan need to be flipped over.

For maximum cooling I installed a B W pressurized radiator ( 4psi cap ) , over flow bottle ,fan shroud , engine pans ,6 blade fan. With this set up you can fill this radiator up to the bottom of the inlet nozzle ( more water in radiator than original ) Reduced my temperature 10 degrees from 195 F to 185 F when its 96 F here in Texas and I am running my AC.

Duffy, Do you turn the heater water completely off in the summer? ie: valve at both ends of the heater.

Earlier Volvos also had a pressurized, round, coolant expansion tank with a 5# cap. Just run it's hose to the end of the overflow tube, and instantly, you have a pressurized system. It'll mount EASY in the left side of the radiator shell. You DO need to have a LEAKPROOF cap on the radiator! Bill W.

I have the heater disconnected . Really do not need a heater here in Texas . The AC /Heater set up was in the car when I purchased the car from a fellow in the Dallas Club . It was disconnected then ,so I just left it like that. For the heater to work you will need a 180 degree thermostate and as cold as it gets in Alaska you may need to still block some of the air coming across the radiator .. My main need here in Texas is AC and not over heating in the summer when running AC therefore I presently run no thermostate .

Thanks Duffy,
I have a 160° thermostat, and the heater is putting out plenty of hot air within a couple of blocks of driving, and works just great. Of course, it's not all that cold here yet. (50's - 60's) Winter will tell more. I do have a Globe Winterfront I can install if it becomes necessary to block incoming air. A/C will come in real handy next summer when we go up to Fairbanks where it gets over 100° quite frequently.
