Here is where my oil cooler is situated

Oil cooler should be fine aslong as it's not gummed up can someone confirm that the fan is backwards. It is easy to flip it other way. There may be easier ways but I would drain the coolant take the radiator out of the way then the fan is held on by 4 bolts on the waterpump. Fan on the wrong way round will make an massive difference.

Ok so I guess just need confirmation about the fan. Have conflicting info on that now but I agree if it's on backwards that'll pretty much be my problem.

Are there better fans to get? Are more or less blades better at moving more air?

[cooperS]

the fan is on the wrong way!, but if you can use the 6 blade fan, also check the coolant ans use a good quality one

[crackfoo]

Dang it. Well I guess I'll get a 6 blade fan and replace it as well since this one is pretty nicked up. I'll let you know how I make out once I can do the change.

[dyshipfakta]

Nice one that's an easy fix then! Would put you stat back in too.

[crackfoo]

Easy in theory! I've never taken my rad out so It'll be a new job for me. Hopefully will go ok.

Any tips would be great and I'm assuming I HAVE to remove my rad...

Hi
For overheating.
First see if your ignition timing is right;if to retarded can cause overheating.
Next make sure your carb mixture is right.
make sure your radiator cap is in good condition .
Get the fan the right way around .
check all hoses and water pump arnt leaking.does water pass through thermostat housing into radiator?
If not stuck thermostat.
Does your coolent level go down?

Would be easier to yeah. It's super easy if you want to reuse coolant though make sure you collect it into something clean. Only potentially tricky part is the stat housing studs as they tend to snap. It's all just screw driver and afew sockets.

[crackfoo]

Yeah I've just replaced my stat housing studs with stainless ones. One of the old ones was rusted into head.

I've heard horror stories about the bottom hose so mostly worried about that.

[dyshipfakta]

Nah it's easy and if it's ropey motor factors usually have them on the shelf and mine I think was 11 pounds .

[crackfoo]

I'll give it a go. No one here has anything on the shelf for minis. I'm in Nova Scotia so if anything breaks or goes wrong I have to order and wait for the delivery and hope it was right! :)

Ok, I just flipped my fan around and it does seem to blow better and the temp stays down. Didn't get to go for a typical drive like into work, but it seems better overall. Amazing though that whoever put the fan on... couldn't read where is says "engine side"!

 

It was actually a lot simpler that I was expecting. I only had to disconnect my top hose and take off the electric fan.

 

Now though with it the correct way, it's not as close to the rad and seems there is quite a bit of air blowing out the top gap between the cowling and rad. The spacer is on but now there is a about 3/4" space between the fan and rad. It used to be 1/4" away when it was backwards.

 

Should I get another spacer and put it on or is that gap typical?

 

Since it was pretty easy to do, I'll be getting a new fan as I think the current one is pretty warped so probably still isn't as efficient as it could be...

 

Thoughts?

 

Thanks!
