Fan removal without draininng the engine?
I'm having trouble with the serpentine belt tensioner bolt, its rounded off so I will need to take out the fans to get better access.
The workshop manual says drain the coolant and remove hoses, however I thought I would check here first to see if anyone had done this without draining the coolant?

Agreed. 2 nuts, like Gus said watch the bolts sticking out. They are not secure once you remove the nuts (I lost one once).
You need to put hood in service position. disconnect the upper radiator hose. Remove nuts. Disconnect the two fan electric connections from the motor and the wire clips on fan body. Tilt fan forward. Lift upwards and out.

It appears that only the upper hose is in the way of removing the fans. If you have a small hand pump you could suck the coolant below the thermostat and not have to drain the entire system.

Good idea about pump. Don't forget you are only going to lose a small amount of coolant if the hose is just disconnected from the radiator side and pushed vertical while you are working.
Probably enough to concern you if you have a dog though. I'll never forget how poisonous it is yet they say it takes great (being serious not funny subject).

RD, sounds good. It will take about 5 minutes over all. Hey, an idea for you. After I lost one of those screws, I decided to squirt some Goop brand glue into the slot that holds the screw. Now it can't fall out and the Goop is like silicon - you can remove the screw if you want to someday.
remember that the top of the fan is flush, no gap, with top of radiator. Easy to miss align on reinstall.
Good luck with it.

Howdy Folks:
FWIW, I made this double ended tool to remove both belts without undoing the coolant hose connection. (I did have to figure rotation and height of the square before cutting the square hole and welding since there is so little clearance. I used 3/16 X 2 barstock)

I made up a similar tool to release the tensioner but there wasn't enough space to get it on the bolt without bending the fans even with a special shallow socket.
I managed to get a hack saw blade in to cut off the spinning nut once the top hose was off.
Fans out, the hood was just in the normal open position.
Then there was plenty room.
Cracked off no problem in the end with a 6 point OTS.

Well that's it done, the car has been off the road for most of the last 3 months, I have spent at least 80 hours working on repairs, maybe more.
The last job today was to refit the fans and rad top hose.
As one of the captive bolts spun in the plastic housing on removal and had to be cut off, I needed to modify the replacement to allow reassembly.
Here are the original bolts and replacement.
Welded the new bolt to some 2mm plate.
Cut it off and cleaned it up.
In place ready to accept the fan unit.
Once all buttoned up I started it up and took it for a very short run (MOT and tax has expired) and all was well! Mot booked for next week.
It started off with a quick look underneath to see if any maintenance was needed........
Replaced lower steering column to tighten up steering response.
Replaced both rear suspension sub-frame to body brackets due to rust.
Replaced driver door catch due to cosmetic wear.
Refurbed all four road wheels due to kerbing.
Refurbished both front brake callipers, new pistons and seals, routine maintenance.
Cut out and welded in new front seatbelt anchor plates on both sides due to rust.
RH suspension turret, cut out rust and made good.
RH wing support bracket, cut out rust and made good.
RH wheel arch to floor panel, cut out rust and made good.
Front cross brace, media blasted and painted, routine maintenance.
New front brake pads, LH and RH, routine maintenance.
New rear tyres, routine maintenance.
LH & RH inner sill lip up to floor panel stripped back to bare metal and repainted, routine maintenance.
Manufactured stainless steel washers for the front upper arm poly bush set, improvement.
Stripped out old front upper arm poly bush set and replaced with new improved design, improvement.
Refurbished driver seat bolster due to wear.
Fitted replacement catalytic converter.
Fitted new serpentine belt.
What a marathon!
