How to MarkVIII your OBS on a budget..!

[Monstar_est87]

Yes thank u... 3500 aux fan is going 2 b my push fan... Just haven't gotten around to it...

I did mine a little different. I bought the one piece adjustable fan controller for 40 bucks and had no problems with overheating or ac. I am running a 180 thermostat and it stays around 180 185.

Yea I did my set up the way I did bcuz I went through 2 O'riley and 1 AutoZone temp controllers... The relays kept burning up... Lead to a cracked rad and failed water pump... The fan draws as high as 60 amps... But if u got 1 that works 4 u great...

May I ask what is this?

Regarding the main subject I habe the following questions:
1- why don't we use a Nissan efan control system?
2- I think you have to isolate the efan so no hot air well skip the shrod and return to the efan.
3- I loved the one fan idea instead of the dual system but why you did not continue with the push efan it is easy for you now? 4- why we didn't study the Toyota sequia system? It comes with dual push and bull efan!!?
5- why you didn't use another after market efan controller?
6- can this volvo efan controller take the high amp? (Caused by the efan start?)

That is a mess lol, I guarantee that truck doesn't cool right.

For one that is not my fan controller you circled on the fan that is the factory chevy waffer fuse. The fuse blew when I put my second battery in(positive cable hit the bottom of the battery tray).That's why it looks that way. Pic was took before I chanced it.
Secondly the truck stays cool 180-185 degrees even with air on. Guarante what you know not what you guess.

Also the fans job is to push or pull outside cool air through the radiator ( depending on where the fan is mounted). If my fan is pulling enough cfm to cool the coolant before it reenter the engine than its doing a damn good job.

The picture I was asking about that part because I couldn't find in mine! Nothing like it is install and is it a must?

 

[Monstar_est87]

That thing in the picture is on our stock fan shroud... Its something to do with the battery... I can't remember the name off the top of my head at the moment...

 

[saif najd]

This is my fan setup:

I think it is taken from a subaru but it is fine I think

 

[Monstar_est87]

Looks good... How is it being controlled..?

 

[oakdog]

How much cfm do these fans pull? If you know.

[Monstar_est87]

I believe low is 3200 and high is 4600 cfms... Just off the top of my head...

 

[oakdog]

Not bad

Monstar_est87 you were right about the mark VIII pulling 60 amps. I haven't had any problems but I am coming up with an alt controller.

By 3 relays this the modes:
1- both working full speed to cool it down
2- if no need to cool the the radiator but the A/C clutch kicked ON then single fan will work
3- if both are working and the A/C clutch kicked ON then one of them will work for the A/C and the other will continue for the coolant.

I figured it out soon it was done by the previous owner actually

Yea they can draw quite a bit so make sure u get a relay or relays that can take it... And a self resetting fuse aka circuit breaker...

Good work saif najd... Electric tape and wire loom go a long way 2 protect ur wires and clean things up abit...

I remember you told me about this when I first got my Tahoe. Just barely found the thread. I wanna do this with a Jegs kit. I will get the fan for $14 from the junkyard. My only concern is the power draw. Will I need to upgrade my alternator? If I have to, this mod will have to wait for awhile.

 

[retorq]

I ran dual fans with the Jeg's kit for a while with the stock alternator. It's a good idea but you don't have too...
