Changing it every 50,000 miles????
Must make a note in the calendar for 2120.
That sounds a bit more sensible than this changing it every year business!

Correct Colin, thanks. I know its best to have a cowl round any fan to optimise its performance as the air will always try to take the path of least resistance which is round the rad rather than through it...
-
Hmmm this will reduce the cooling effect of the fan but no idea by how much. Interesting to see if you find any difference...
-
I look with envy at the WSM where the proper Triumph tools pull bearings on the inner races not like using a legged puller on the outer ones which seems a bit animalistic☹️
-
Pete are the output shaft bearings generally any good after they've been removed or are new ones required with the seals?
-
Id recommend doing the input shaft seal as its easy and is much more likely to leak (3.27 times more revolutions?) but the output shafts are a lot harder and luckily I havent found they have a problem even after 50 years. And yes the nut will require a 1 1/8" (or 30mm?) socket and bar plus some way of holding the flange for which there are special tools (see ebay) or various other less professional methods😏
-
The fairpoint.net site has a good table which shows all models of GT6, Vitesse 2L, Dolomite 1850 and Tr7 (4 speed) had the same ratio forward gears. However apparently not all are the same design as there were changes to teeth angles and synchro cones.
-
Sounds good Graham, only I don't understand the diff bit. The two gearbox ratios are identical and the OD just drops the cruising revs. The OD diff will give faster acceleration than the non OD one with either box. The idea was that with an OD model you had better acceleration but kept the relaxed cruising as well...
-
worth saying though that the Chinese rads may not have all these benefits as they sell on how many rows theyve got while, as said, 2 rows of 25mm tubes is better than 4 rows of 10mm ones....
-
Oh alright I will then. Copper is a better thermal conductor but aluminium is a stronger metal so the tubes can be made with thinner walls and deeper. The best alloy rads will have tubes that are each 25mm deep which is better than two separate tubes with a space between them. Then there's the fins which are brazed to the tubes in an ally rad which is supposed to give a better thermal transfer than the fixing used in copper units. I believe copper is fighting back on design but so far is way off on price. There I've done it!

What diameter, Pete? I know the Herald coil version is 6 1/4 inches so presume the Vitesse one is beefier?
My MK1 is 8.5"

Noooo dont start the copper aluminium argument😱

I've got a Honda Civic jobbie installed on my Vitesse and all good for the last 3 years. There's been threads about the Spitfire version and the only problem noted has been the poor angle of the top connection. It doesn't line up well with the thermostat housing and one guy had it cut off and rewelded....

Hi,
the Escort one has no coolant header. The rad will always be full of air. Great for corrosion unless you run it waterless.
Cheers,
Iain.
The Chinese MK1/2 escort ally rads on eBay are very similar to the Honda one with a normal prv cap that vents to an open expansion bottle so suitable for use on an original Vitesse system.

Johny with the Escort rad will you have to trim the side brackets off to make it fit?
The photos I see have what looks like a 40-50mm aluminium right angle welded to the side of themAlso a Datsun 510 610 620 710 720 L20B Manual radiator looks like it might fit
I havent fitted it up yet but the measurements look really good. Much the same as the Honda rad I was going to use the side brackets it comes with to bolt angles to for the mounting feet (but yes below those the rest of the brackets might need trimming off) and also small angles higher up for the valance fixings.
Its probably going to be overkill because I have a standard engine and, although I drive in very hot conditions sometimes, believe the law of diminishing returns applies. That is as you cool the coolant more the difference in temperature between it and ambient air reduces so the energy transfer is reduced and you need even more cooling surface!

No Idea,
The car hasnt been on the road for 37 years but the radiator looks clean when I remove the cap. I straightened the fins a few weeks back and that was when I damaged the drain tap.IIRC I had the radiator worked on about 20 years ago😉
I was looking at Ford Escort Mk1 RS2000 radiators today and they look like they will almost fit and the hoses are in the correct places.
But as I have temporarily become one of the unemployed I think I should reduce spending till I get work againYes I've got a 4 row ally Escort rad new from eBay at 90 pounds waiting to be installed in my Vitesse. It should be very good fit and look great but I'm loath to disturb the Honda set up as it works so well!
-
Pity but don't you have any overheating problems? I would have thought the state of the cooling fins and interior cleanliness of your rad would have caused an issue by now....
-
Hmmm that sounds like a good way to justify it to the missus.....

And hopefully one last question.
I see you have an electric fan but did you try it with the mechanical fan as according to my specs the Honda rad is 100mm shorter than the Vitesse one.I dont see any problem with using the original mechanical fan. True the Honda rad is not as wide as the original but fits more tubes in less space and if mounted centrally should get good coverage from the crank fan although Im not sure how close the bottom hose connection will be...
Sorry havent got any pics of my installation which looks easier than John's although not as professional!
-
Yes it wants to be as high as possible to make it easier to fill the heater. Mine works as before, I put coolant in the rad and half expansion bottle, then while driving operate the heater knob a few times and it starts to work no problem.
-
Yes some normality has been restored! That'll be the bigger ring and they're worth having as the older type seem to wear out pretty quickly.....

I would like to feed back, but I have to sit at home with this gorgeous weather working, and having to wait until the weekend.
Basically I need to make the cover plate of the prop shaft, fit the gearbox cover and the interior. Service and then get an MOT at my local garae who I am attempting to keep going by getting varous modern family cars seriviced and MOTed. He has seen his MOT business drop and the folow on work.
I have booked off a holiday on Friday to get it done.
Easy enough work but the just need to get out there.
Hoping to get it MOT next week.
AND PETROL IS SO SO CHEAP!!!! no way to go
Graham
I can see the problem with work getting in the way but one thing you might be best off driving it before the cover and interior goes back. This will be noisy but could be useful for leaks etc

It has the same synchro rings as Vitesse / GT6 and gearset from Mk3 GT6, which seems to differ in the angle on 1 gear, possibly second, to a Vitesse
Im losing the plot here, as listed by Rimmers I thought the 3 rail boxes in 1850 (s/n WM) and Mk3 GT6 (s/n KE) all had the larger synchros and all other GT6 and Vitesse had the small ones. You can easily tell the synchros apart because the small ones had 4 channels cut through the cone grooves and the larger had 6....

AC Delco fuel pump Vitesse Mk1
in Fuel System

The repair kits for the usual Vitesse pump are widely available but I got a new pump as there wasn't very much difference in price. There seems to be two models available, mine has the inlet connection in the top cap and came from James Paddock. It's been fine and it was a lot easier than changing the valves that leaked in the old unit.
