Hello!

[pyemaster]

I think a few people here have the TM2 and a few the engine saver low coolant alarm, has anyone got the combination product?

Seems a tad steep at £170? Or is that about right?

It's probably gonna be low on oil.
The easiest thing to do is to get some shock oil from your local radio control car shop or eBay.
I got mine off eBay for less than a tenner.
I used 10000cst although I think it is 3 or even 6000 cst originally.
60cc btw.

Follow the guide on here to take it apart.
I used an impact driver to ensure I didn't damage the screw heads.
Split the casing
I used a thin blade worked all the way around the seal then a light tap with the wooden end of a hammer and the casing halves split open.

Drain out the remaining oil and flush out to remove the remainder

Check the seal is still ok?
I happened to have a o ring the right size

Pour the new oil in make sure you use all the oil and carefully reassemble.
Follow the guide on here it has pictures to help you.
It is pretty easy once you have the fan out.

Ah okay, right.

Well I've just had my original radiator recored and pressure tested, etc, so that will be operating very efficiently all being well.

Symptoms are:

Relatively stiff to turn when cold.

Ran it for a few miles (in cool morning temperatures) to get it to operating temperature, switched off and let it cool for a min like you suggested, checked it again and it was able to spin a little more freely. Not freewheeling, but requiring less effort to get it to turn. If I gave it a proper shove it might have span for maybe one or two blades before stopping. So not much, but definitely easier than cold.

After an hour-long motorway trip yesterday (it was a warm evening but not hot), and with the truck as warm / hot as you would expect from a long run, I checked after I parked up and it was able to spin very easily.

The truck operates fine with no overheating in day to day commuting, town, country, hills, motorway, hot day cold day, you name it. The ONLY two times since the work was done that the temp gauge has climbed was after a long very steep hill (gauge climbed to two-thirds by the top but settled down quickly afterwards) and on another long hill (not as steep, but this time I had O/D off as a precaution), and again it climbed up near two-thirds on the gauge and backed off back to normal quickly at the top.

I'll see if I can work out how to check the fan oil, though now I'm confused that maybe it's working fine, it's just it hasn't got hot enough yet for me to check if it locks up?

Just because the engine is hot doesn't mean the fan is in lock up.
The fan needs to sense hot air at its bi metal sensor to lock up.

The fan will be stiff to turn when you first try to turn it.
After the engine has run for a few mins the oil will be forced out of the clutch rings and into the reservoir
One way to check it is to idle he engine till normal temps are reached
Turn engine off leave for a few mins then try to turn by hand if working ok the fan will be stiffer to turn hence lock up
Putting new oil in is fairly easy search for a how to here

[pyemaster]

Tested the fan tonight, stiff to turn when cold and a doddle to spin when hot. Argh!

Now it hasn't been overheating at all since the work has been done, but the temp gauge had risen above halfway twice after long, steep climbs... Could this be a factor do you think? I was under the impression it didn't have much effect on cooling over 40mph?

Sorry for the newb question but is it easy to check the fan oil level / replace the oil?

Viscous fan

missed this very long and interesting thread from a while back.

pyemaster - I bought a similarly re-built surf (however is a third gen) - recent new head, rad, thermostat, pipes and bunch of other stuff on the receipt when I got it. Within a fairly short time had all sorts of boilover and temp / white smoke issues. Hoping it wasn't another head gone I stumbled on the viscous fan threads on this forum - and sure enough when i poked a rolled up newspaper into the fan it stopped (hot engine so the visc clutch *should* have been engaged).

I replaced the fluid with 10000cst from fleabay and fitted a external water temp gauge and haven't had a temp problem since (had my share of other mechanical ones tho boohoo/haha). I have to assume my engines still in alright shape?? Fan sounds like jet engine which probably isn't great for fuel economy but temps are rock solid.

So if you've spent all that hard earned cash look at that mod, mate. Having a properly operating fan is kinda important ;-)

[pyemaster]

Couldn't agree more! I'm actually using the truck as my wedding car on Saturday too, so I'm a little annoyed at the timing.

Little fcuks want stringing up

[pyemaster]

Always nice to wake up and find some little scrote has keyed your car over a few panels. I wasn't planning on it being a show truck or anything, but still, it's just the principle. Hope it's a one off.

Haha sorry, posted off my phone using the mobile site which seems to automatically resize imagery for a phone screen, no idea how big that is on a laptop.

Owen

It is quite large

Perfect if you are dual screening



I will keep a eye out for it, the number plate will jog my memory.

How it sits at the minute.



Owen

I'm sorry its a bit small.
Could you take a bigger picture?

Hello and welcome! a fellow Oxfordshire surfer!

Default........
I was talking yesterday to a bloke in Tool Station who has been running his van for 7 months now after using the stuff I put in, he used 2 bottles and said that I should have done the same as my engine is a 3 ltr, but we'll see what happens.

Does this bloke's van have a Surf engine/head in it??
