4.0L OHV Soul crushed and seeking advice on starting problems


This is how I removed my fan clutch. It's easier than messing around with wedging stuff in the WP bolts or the worn out rental wrench from AutoZone

Thanks Rob
I actually just got it out about 20 minutes ago with the help of my friend.
We had to cut down the tip of one of my pry bars so we could cram it under the bolts on the pulley and angled it so turning the fan clutch counter-clockwise would lodge it under the power steering pulley.

That plus a mallet did get it off!
Tomorrow I hope to wrap it up and fire it up again sometime in the afternoon... let it get up to temp, then cool down and do an oil change + check the coolant levels.
Should also give me the chance to verify the electric fan kicks on when it's supposed to.

It should start a lot easier after this so hoping the less than mint condition flywheel won't get in the way of at least wrapping up the current work to it

Nice! Once that fan and clutch are out of the way, it's so much nicer to work around.
 
So I got it fired up today! Didn't get the cooling system all set up so I only ran it for a min or two.
Still has a stumble at idle and also a new tapping sound from atop the engine. I assume I lost a washer or something under the valve covers and will be checking in there.

I didn't tighten the clamps down on the intake hose so I am kind of hoping that's causing the wonky idle as I was really hoping it would idle right after this work.
Other than the already noted sounds, I do believe that the engine sounds more quite than before. Under the assumption that sounds is something stupid & simple, this will have been a success.

Also, the all aluminum radiator looks nice from the front! Really noticing the surface rust that I need to clean up lol.

For those who are wondering about the radiator fit.. it's so-so. The mounts weren't quite right which caused it to sit further forward on the right side.
I did my best to correct for this by bending the mounts a bit with a pair of pliers and using the very same strut mounts these trucks use around the top radiator pins to take up the space and hopefully keep it from rattling around.

None of the hoses fit right which I kinda expected.. I had already ordered MT hoses and this is an AT radiator. The top one was workable and fit okay-ish after some cutting, the bottom one would get crushed.
Actually the bottom in general is quite bad the radiator basically sticks it right at part of the suspension / subframe. I wish I got a picture but I ended up using a flexible hose and warping it with some plastic shielding off my two other lower radiator hoses.
 
Nice to see some progress!
 
Well that explains a lot lol. Guess it wasn't quite seated right when I tightened everything down. I will torque this down in the AM and then I am expecting it to be much quieter and to run smoother

Check carefully for damage. My luck it'd be slightly bent.

That would be pretty typical for my luck too lol.
I actually slept poorly and chose to have a lazy morning before going to work so I haven't touched the truck yet..
I will double check it's not bent though I do find it unlikely. I didn't rev the engine out and it didn't seem to be bouncing around very hard as I couldn't find any distinct markings on the valve cover.

The radiator came with a temperature switch that imo doesn't make sense. It's rated for 185/175 and I bought a factory spec 198 degree thermostat..
I decided to order 2 different 1/8th npt switches as I had already bought a housing to add the sensor inline with the upper radiator hose per my friend's recommendation.

One of the switches is rated for 210/195 and the other 200/185.
Since one of my wishes from the e-fan conversion is efficiency, I will try the 210 switch first as that should give the radiator a chance to cool the engine without the fan...
If that doesn't work how I like (or the switch is a dud) then I have the other one to try which I think should still fit well with the factory thermostat spec but would probably end up running the fan a lot more often like even when cruising on the highway.

I probably won't have an update for a few days but I am excited wrap it up and see how it runs. I listened to an old clip from around when I had bought the truck and I think that the engine is quieter (ignoring the loose pushrod).
So I am looking forward to having the cooling system in and being able to actually take it on a drive :)
 
I wonder what temperature factory efans usually turn on and or switch to high?

I didn't find too much in terms of very explicit numbers when I did some quick googling yesterday but it seemed like in general factories do similar to what I was thinking.. likely for the same exact reason.
Though I think if you were doing a high performance or off-road type of application there would be some logic in the 200/185 option (assuming this is the range you want it to stay at).. if the switch is accurate it should switch the fans on as soon as the tstat lets water through and then turn off a little after it closes. Probably run most times other than at warm up which is the one time you for sure don't need it..

none of that shit matters if its for dead numbers unless you are lucky.


where you actually put the sensor is a key thing as to what the rating will work best at for actual temp control and lowest cycle times.

best to have an adjustable controller from a fixed point. that means you need to know the actual temperature of the point you choose to use....which requires a gauge of some sort
 
of course with these things....there is such a thing as close enough.
