I am experiencing overheating just when pulling a small 2 wheel trailer with a lawn mower. I have read that I need a Hayden fan clutch and an 11 blade nylon fan. I have a couple of questions:

1) Is the "severe duty" Hayden fan clutch the model 2905?
2) Is it accurate that the 11 blade nylon fan moves more air than the stock steel fan?

Thanks!

The nylon fan moves less air, but also consumes less HP when the clutch is not engaged. The Hayden cuts in at a lower temp, so this combo controls high temps fine while minimizing MPG hit.

When my stock fan clutch died, I replaced it with OEM stock. I tow quite regularly (ATVs in summer/Snowmobiles in Winter) and tow up some steep and long mountain passes without ever overheating or temp gauge exceeding 1/2 way point on gauge.

If you are overheating under those conditions, then something else is going on.

What coolant are you using?

Have you recently had the coolant replaced?

Are you seeing any coolant on the right of the reservoir in the morning when the engine is cold? Are you losing coolant?

Does the heater work?

Is there any pressure in the reservoir?

Do you see any bubbling or change in coolant level when revving the motor?


Answers to these questions will promote understanding and diagnosis......

Everything works normal, no pressure in the coolant reservoir, but do lose a pint of coolant like every 2 months or so +/-.

Just installed the Hayden fan clutch, we will see if that fixes me up.

Thanks!

Well - even at 100F+ my temp gauge is left of centerline - fan clutch isn't an issue - fan never needs to comes on

can't see a '2 wheel trailer with a lawn mower' making that much difference.

have you flushed your radiator recently?

Check to see that your coolant hasn't turned heavy, close to jelly like.

In my previous CRD the coolant had turned thick, it looked clear, but was thick. Not sure why this happens but circulation is affected and so is the cooling process.

Some say that using tap water instead of distilled water can cause a coagulation type reaction over time when the mix comes in contact with the aluminum parts of the engine. The minerals and especially the iron in the tap water has something to do with it. This slows down the coolant flow and the proper cooling process of the engine.

Top this off with a water pump that should have been designed with a higher flow rate and the system no longer does the job it was intended to do. It chugs along.

So if your coolant is more than 2 years old and has been topped off with regular tap water instead of distilled water, then a coolant flush should be in your near future.

Also, the radiator will become clogged due to this chemical reaction. You will need to use a coolant flushing kit with distilled water.

What coolant are you using to top off?

BTW, overheating under load and coolant loss are characteristic of head warpage/hg issues.
This can be the result of overheating from improper coolant, air bubbles in the head and other causes.

I'm not familiar with the CRD models. What is the stock rad fan? a mechanical clutch fan or an electric fan? or both?

I believe in the gasser models w/o a trailer package it's a two speed electric rad fan.

Recently I've had a lot of overheating issues and not while towing. I fixed my problems by repairing my electric rad fan (it wasn't working at all) and flushed the rad core. All it took was a garden hose sprayed into the front of the rad.
It was some packed with mud.

If you temp goes over 1/2 on the gauge, your in trouble. Should always be just a RCH under 1/2. (for all you who know what a RCH is)

Sorry i don't think your Fan is not going to fix the overheating. My :2cents:

Is there a part # for the nylon fan that should go with this Hayden unit? Is it a Hayden part, or the 3.7L part, or...? I used the search feature, but couldn't find that.

It is the OEM 3.7 gas fan.

All I seem to find online are electric fans, even if I use "tow package" in the query. Guess I need to go on a boneyard tour anyway...still trying to find a silver bumper cover.

In regards to obtaining maximum fuel mileage ....
So the Hayden HD clutch cuts in earlier (hence, at a lower temperature), if then NOT having overheating issues,
is the stock clutch better to maintain higher fuel mileage ?

Also, how many have installed the Hayden HD clutch & only made their under temperature condition worse ??

The OEM clutch, apparently especially the 05, is somewhat weak and failure prone plus it apparently cuts in later in the temperature rise curve. The Hayden is much heavier duty and cuts in a bit earlier in the temperature rise curve which is good as it's easier to stop temp rise early than to catch it late and have to bring temps back down.

Plastic fan is PN 52079654AD or 52079654AE for 2002-07 gas KJ latter # is most recent. Might be a bit lighter which is good for mpg but might move a bit less air than the stock metal fan. I'm ok with the nylon fan but if I had to do it over I'd keep the metal one and spend the $s on something else.

I know several people who do not have a engine driven fan installed. Simply removed it and have been running without overheating.

I did not do this, but it works.

Or just put an e-fan and it's a done deal.
