4500 CFM electric fan for your Titan?

[GregK]

Again, unless you opt for stupidly whimpy fans an electric replacement will always pull more CFM than a clutch fan at idle.

[MilenkoGT]

All i know is for the Price of a used Lincoln Mark 8 fan and its 4500cfm rating on high speed, its def worth the money. And I wouldn't really worry about making a custom shroud, just trimming the stock Mark 8 shroud to fit on the titan radiator.

I mean there are a bunch of guys running the clutch fan setup without the shroud and using the CSF radiator. Granted that is clutch vs electric, but still.... the Electric seems to be a better option to go with if the right controller is purchased and the fan speed comes on slowly instead of a sudden 50-100amp shock to the system upon start up...

What would you guys reccommend a good temp setting for the electric fan to come on and shut off?

my stock fan either had a rock hit it or something is up with the clutch I had to get a new radiator but now I don't know if I want to put a stock blade set back on the clutch housing in case the fan clutch is what went. I was offroading under 35mph and doing quick accellerations to abrupt slow downs and reapeating this past weekend. I could all of a sudden smell coolant and it was getting dark and my temp gauge was ok so I kept going.

about 15 minutes later my temp spiked and I pulled over clearly looking under the hood there was a catostrophic leak (engine was covered and I did notice my voltage would go WAAAAAY down and my belt would squeal for a few seconds and my voltage would come back up. so I was hosing my alt I suppose with coolant/water.







debating an efan or getting a new clutch AND fan to replace that grenaded pos

E-Fan! For sure! There should be a DIY write up on here on guys doing the FLEX A LITE fan kit, but you may not need to spend all that money for that kit.

Just source out some 12in SPAL fans (pullers) and go from there... some of the guys who have the aftermarket CSF radiators have left out the stock fan shroud and used clutch fan with no ill effects.

So you could prob get by without using a shroud with E-Fans, as long as they are good quality and put out some good CFM. The thermostat kits you would use are the probes you insert in the radiator fins near the top of the inlet radiator hose and i've heard they work really well.

VON uses E-fans set to 170* IIRC and they work great.

Plus you'll gain a lil more power, which is always a plus.

oh this is my 2nd radiator in a year and I knew I needed at least a radiator because of the coolant everywhere but then I saw the fan and was like wtf?

[MilenkoGT]

You decide which fan route your going?

[El Mamito USMC]

interesting.. once my fan clutch goes out again ill try something like this..

[Hawaiianbasshead]

I just ordered stock stuff.

my clutch could have caused this I guess?

I really want to do an efan but need my truck running asap, so no down time to learn wtf I need and I work a commsion job so no time to dik around figuring out install or doing the actual install I need serious help if I were to do efan at this point I already ordered everything but a clutch thinking it was the clutch

Hey guys how are you doing I have noticed that you guys have also been toying around with the idea of electric cooling fans for the Titan, as I have been building the kits for the Tundra's and the Titans don't seem too difficult. I have access to a CNC plasma cutter and a source to powder coat, I believe it would be very easy to build them for the Titan using the DC controls 2SP relays Relay Controllers and Accessories and the MarkVIII fan as they are very cheap. I could build it similar to my Tundra kit using a 5052 aluminum adater plate and the fan and powder coating of course for some where in the neighbor hood of $3-400.00 not including shipping but I will need a Titan as I live near KC. Here is my Tundra build!

http://www.tundratalk.net/forums/tun...ibilities.html

So here is the updates I promised, I have spent about two keeks getting drawings made for programs to be produced so that the mounting plates could be cut out on a CNC plasma for more quality and precision. I currently have enough to do five kits not including the parts, I have also went to the DC controls PWM controller that variably controls the fans according to the engine temps. Something else that I am very happy about is the parts are now beeing powder coated with a textured black paint that is very similar to the under hood parts.

I currently have an updated kit installed on my Tundra that is working very well with no problems, the new kits do not require the upper hose to be cut due to the probe that just pushes into the radiator fins and only rquire two wires to be hooked up power and ground. The controller has wires that can be hooked up for fan operation with the A/C on and wires so the fan can be turned off for low water crossing. I am asking in the $5-600.00 range for the kits not including shipping. Here is some new pics with directions, Thankyou for beeing so supportive!




Here is what is included in the kit, fan assembly prewired, extra wiring for optional A/C and manual control, and new bolts for clutch fan delete!

1.The first step is to disconnect ground from battery and driverside fender.

2. Remove engine cover as it well help to have it out of the way.

3. Remove fuse cover and disconnect power wire using a 10mm and then with a small flat head insert into tabs to slide power wire up along with plastic cover and then remove the cover as it will not be needed.

4. Remove lower engine cover with ratchet and extension, 3 10mm in front and 2 12mm in front and 3 12mm in back, ounce removed the cover will held on by two hooks in front so slide them to driverside and lower.

5. Locate the drain **** on the bottom of radiator and drain about half a gallon of coolant into a clean container as it will be reused later. Note: this will make it possible to remove upper radiator hose and the cap can be taken off to increase flow ounce a little of the pressure has been relieved via hose.

6. Remove upper hose to gain access to radiator area and to remove shroud.

7. Locate clutch fan bolts and remove the nuts by holding one bolt with wrench to keep the pulley from spinning while loosening another. Note: The nuts will come off but not the studs, the studs will have to be accessed ounce the shroud and clutch fan is removed, the studs have to be removed to install the new bolts, by tightening two nuts together on each stud efectively creating a way to remove studs with ratchet.

8. Disconnect overflow hose from radiator near cap, and unfasten hose clamp from transmission hoses from passenger side shroud using a long slender flat head screwdriver and move hoses out of way for reoval of shroud.

9. Remove the two screws holding the shroud at the top, and remove both the shroud and clutch fan together, taking care not to damage radiator fins and spilling the coolant out of shroud overflow tank.

10. At this time you may remove clutch fan studs and install new bolts per vehicle torque specs.

11. Now install the new electric cooling fan assembly and take care not to damage radiator fins. Note the lower radiator hose will make diffcult to slide into place but it will fit, now install bolts per vehicle torque specs.

12. Locate a clean rag and some alcahol and clean raditor hose and water necks contact points of coolant as there is a possibilty of leaking, and then install factory radiator hose with there spring clamps.

13. Locate factory shroud/overflowtank and drain the remainder coolant into the clean container for reuse and remove hose and reinstall onto new overflow tank.

14. Run the two wires for power and ground from the cooling fan kit to driver side fender, using a zip tie and a the supplied wire clamp to left cooling fan bolt, and then attaching black ground to the driverside fender grounding point and the power wire to fuse box power lug and tighten all hardware to vehicle torque specs.

15. Reinstall negative batter cable to factory torque specs and reinstall fuse over.

16. Gain access to the black sensor wire behind lower cooling fan rubber relief valve and insall end into a cooling fin, at this time you may reinstall lower engine cover and remove all tools from engine caompartment making sure to refill radiator and coolant tank with the used coolant.

17. Drive and test the operation of the fans as it is set for a 180* theremostat and can adjusted via side screw, read directions for fan controller carefully!



If there is any questions regarding the kit contact me at 660-441-3569, I will include the shipping container for the fan controller and directions. If there is any questions regarding the controller the manufacturers contact info is in there as well, save the electric fan controller box for warranty issues!

Damn that's nice work.

[gweasel77]

Very clean install!!!! Thanks for posting all the pics!!!!

[texasranger96]

I have always had Silverado's and it easy to make power with them, as my last 06 had a front mount 70mm turbo making 500hp on a 5.3. I decided to buy my first Tundra last yr and it is very sporty with the 5.7, but it is very hard to get performance parts for them so have been making my own, and I have noticed the Titans are further along in performance parts, anyways I am just trying to bring something to the table.

[MilenkoGT]

YOu have def brought the know how and quality to the Titan modding table lol. An electric fan conversion with all the right relays and an ease of installation such as what you have would be awesome to own!

And that fan shroud is what i'm talking about lol, thats good stuff.

So what all are you needing from a Titan owner to make this happen?
