Hello I beleive you have found the problem. First off you are right that is not the correct fan for your van, and also the spacing is most likely off and both of those will no doubt cause your overheating condition. Something else to look for that is often left off in a repair like this is the flaps and plastic covers that help route the air through the radiator, condensor and other coolers, without them airflow is restricted and can even be directed away or limited the best and easiest thing you should do is compare your van to a known good one, I am sure there is one on a car lot near you pop the hood and compare. Around here we have pull-a-part, a salvage yard where you go and remove your own parts going and removing them would save you money plus your guaranteed to get all the small pieces you need.
I apologize sir please yes i can help you do anything you want to the van. And to answer your question no they have used a clutch fan or electric fans for years and your year model van had one of those
And that four blade fan havent seen one of them in years your van come with a 5 or 6 blade. And i said what i did about going to the car lot becauase in a situation like this when you have something wrecked that you bought after the wreck therefore you are not sure the alignment or positioning of things having a known good one right beside yours is worth a thousand words.
Oh and sir i see the 50 dollar phone call i did not put that up there not sure but will be glad to talk to you on phone, video whatever i can do to help you fix this van
You are correct it would be a thermal clutch, you can take your vin number and go to the dealer or a good local parts house can look it up by application.
What shape is your fan shroud? And the Radiator do you think it is the correct radiator?
hello how are you . I am wishing to offer my assistance to try and help solve your problem
okay . I am reading about the situation with the " fixed " fan blade . have you changed back to the OEM thermal fan clutch and factory blade ?
so I understand that you are experiencing overheating issues ?
okay . I did not see the pic but that is okay . normally the fan blade needs to be " within " the shroud in order for the shroud to serve it's purpose . Short of installing a completely OEM fan and clutch set up back on if you choose not to go that route , I would suggest buying a fan blade spacer to move the fan into the shroud . additionally typically the clearance for the fan blade to shroud is 3/4 " to 1 " how does this fan blade fit ? if the shroud diameter is 20 inches and the fan blade is only 16 inches for example then that just will not work . Additionally , I read that you " flushed " the radiator . I would still have suspicions of a partially plugged radiator . But we can get to that . we can stay focused for now on the fan issue .
hi . okay . the fan is small and you need a bigger fan . you also need to move it closer to the shroud . Also from the view I have of the image if it has not been reversed during the transfer of the pic that fan must rotate counter clockwise when viewed from the front . Can you confirm the rotational direction ?
yes it is very possible to reverse the rotation of the fan by installing the belt incorrectly . It happens frequently
the fan must rotate in the correct direction . it needs to " pull " the air through the radiator . The fanmust rotate in the direction of the leading edge .
this an image for a CCW direction fan . the pictured you have looks like the fan on your engine needs to be rotating Counter clockwise
the fan clutch design was originally engineered as a method of reducing fuel consumption and increasing availablr horsepower .
no it is fine . I have installed those PTO systems before
did you confirm yet that the fan is spinning in the right direction ?
after further review of the pic and the belt I can see that the fan is rotating in the correct direction
May I suggest what I would do if it were my vehicle at this point ?
okay . IF this is my vehicle and I NEED it for work ! I will replace the radiator and the thermostat . It hase been running and working in this configuration I assume more quite some time , years . The fan / shroud is not likely the cause . replace the radiator , thermostat and fresh coolant .
you need to phone the dealer with the VIN and they can tell you that
