Cool down that engine

Mine is a chevy 350... My temp sensor for my gauge is in the driver side head, so I have one temp sensor on my intake and the other one in the passenger side head for the fan, not a ford guy so not sure of the available ports on ford engines....

MO put a standard belt on it with out the ribs and it will solve your problem the aluninum and chrome pullys will slip with that style belt belive me I have been there..!!!... ..My 307 runs around 185 driveing around town with a electric fan but will climb to 200 -205 at speeds over 60 mph.. If I am sitting at a long light or in traffic it will climb to 210 but never goes over that..!!!. Unless you are boiling over the motor is not running hot when you get to 230 then you can start worring... ....All earlys have air flow issue's because more than half of the motor and radiator is in the van.!!!..I think the 2nd Chevy's have the best setup with the floor tunnel..!!!..JMO..

Changed that belt long ago...no more squeaks. My temps have never gone over 195 so I'm pretty happy with this setup.

Great thread, guys.  Great info.  Mo, your info is most helpful in terms of same engine size although you have the second gen. tunnel.  I only have a scoop.  If someone can post a photo of the second gen. tunnel, it would be helpful as would like to have that added to my setup.

This is a timely thread as I had temp. concerns and issues when I first got my van and it made driving my van a nervous adventure, especially in our brutal summer heat.

The best/newest thing I learned is the bigger amp concern (I am sure mine is stock and my headlights and dash lights were always dim) and the concept of getting a bigger capacity Ford as referenced.

This is the link regarding my temp. questions and it has a lot of good, related info.  I was getting ready to go back to it to re-educate myself when I saw this current thread.

I have not purchased the Hollister piece yet, but I definitely plan to do so.

Here is the link to the related thread for future reference purposes:

Thanks, Joe. That seems pretty simple.

Would the Second Gen unit bolt right up to a First Gen or were there different setups underneath due to the stock tunnel vs. no tunnel?

I also have had my doghouse added, presumably from a Second Gen. Where does the tunnel run to and from?

scroll through here, there is a bunch of 2nd gen into a first gen dog house pictures

There's a video we've had for a long time here, third post from the bottom of page.

I think if I had a first gen van and wanted to add a tunnel, I'd make one even larger than what the second gen has... Perfect opportunity since you have to cut out the floor anyways.

Thanks for the head's up. Mine is already converted for auto and the motor is currently out, so probably a good call.

I spoke with the owner of Hollister Road that builds the wiring relays for the fan motors.

He added some interesting info that was not discussed here. He said that the T-Bird and Cougars also had the same size fan as the Mark VIII BUT were two speed fans. He said there is a misconception that some Mark VIII's had two speed motors in some, but that he had never seen one that was original. He said any Mark VIII that had one was a replacement from the less expensive or more readily available Cougar or T-Bird.

He also mentioned that the one speed motor of the Mark would not work (obviously) but the motors were nearly identical size and that the two-speed Cougar/T-Bird fan motor would work with the Mark VIII fan.

This might open up some option and make finding the larger fans easier.

I encouraged him to post here (he joined two years ago when I spoke with him.) He should offer a discount for VV members.

Interesting news about the Mark VIII fan. If the cougar/Tbird fan is an 18" it would fit the 2nd gen V8 cross flow rad perfectly. I have the 17" fan on my Cross flow and it is about 1.5" smaller than the rad.

Just ordered my two temp relay with optional fan plug.

Check out this newer product.  I would have gone with it instead, but since I don't have a tunnel yet and it's strictly radiator temp sensed, I decided I am best having actual engine temp sensing.

It would seem in regular vehicles with more effective airflow to the radiator, this might be a better option.

He said it will work with any fan and that is will ramp up the speed depending on need. This is essentially what comes with the single speed Mark VIII fan, which allows it to ramp up or down depending on need.

His example said that by radiator sensing, it would cause the fan to NOT come on at hwy speeds as the radiator should do its job without needing the fan and putting strain on the system by having the fan come on.  I didn't think that was a good thing for our vans unless we have a tunnel setup or effective shroud, etc.

Guy is very patient and a pleasure.  I would recommend chatting with him if you have questions.

They also make a higher amp version:

Going to make my own 2 relay system for the Taurus fan but my question is Relays. Was looking on Ebay for relays and 95 percent are from China or Japan. Has anybody bought these relays and are they good?? do they last. Seems like the 30/40 amp relays are made here?? but the 80 amp relays are clear and are made over seas. Was wondering if anybody had a different source

Thanks
Jeff

www.delcity.net | 1.800.654.4757 I have purchased relays and power window switches here. No problems.

Hey Vic have you hooked up your Volvo Dual Fan Relay yet?? If so what Sender unit did you end up using for Temp rating. Did you use a relay and if so what Amps. Not sure if I should go with the dual relay or the Volvo fan relay now...information overload

Got the relays and cool down timer wired up for the Taurus fan today
