Hi johny. I've only had the car a few weeks. And I've been using it as much as possible. Including a long run when I picked it up. However, she did dump all the coolant the other week. No warning from the temperature gauge. Cured by a new radiator cap - The spring had rusted away and I could easily squeeze it between thumb and forefinger. It was stamped 13lbs, so I replaced it with same.

Thanks Pete. I guess I should order a new pump... I'll be sure to put the hole at the bottom when I fit it.

Working on my GT6 today, I noticed a grease/oil spatter on the underside of the bonnet. Also some spots along the fuel line and top of the coolant expansion bottle. I think it is coming from the small hole in the side of the water pump. Is the pump on its way out?

Is that cup or cap fulls? Asking for a friend

Well, I didn't get to take the tunnel cover off this weekend. The weather was too nice and we decided to drive her instead. I did replace the relay and it was an opportunity to decipher the PO's wiring. The new relay was working - just the same as the old relay... But then I noticed the fuse was hot. Really hot! "Ah-ha" I thought (more like a, "You idiot. Why didn't you think of this earlier?" thought). I put an ohmmeter from the relay output pin to ground and, you guessed it, zero resistance. None. Nada. Zip. Definitely a short circuit. Or a cooked solenoid. On the bright side - at least I now know why the overdrive stopped working.

The switch is on the steering column. Yeah, according to the receipts the gearbox and OD were fitted as part of the restoration in '15. The relay has 5 pins. The middle one is unused. There's a 12V (fused ) feed, earth (bottom of the photo). And 2 other (both red - very helpful) wires that go through the bulkhead, then back down under and alongside the transmission. I went underneath again, and I can't feel anywhere that's rubbed or frayed through and possibly causing a short. But I won't know for sure until I get the tunnel cover off and have a proper look. I might just replace the relay for now. That's cheap and easy.

You're right. The fuse is in the feed to the relay. I was probably so excited to find the blown fuse which I was convinced would solve my problem that I didn't check whether it was coming in or out. On my car the relay is bolted to the back of the driver's side parcel tray. I'm not sure if I was testing it correctly, but both the output wires appeared to be "live" (current between terminal and ground).

I think you're right Clive. But it will have to wait until the weekend - my garage is much too small. I hope the weather is kind.

Finally got a chance to take another look today. Scrabbling around under the dash, I discovered a blown 30A blade fuse - not in a proper fuse block, just plugged into a couple of spade connectors. I didn't have a 30A fuse to hand, so I borrowed a 25A from my Land Rover. Before I plugged it in, I put a meter across the connection, put her in 4th and turned the ignition on. Flicked the OD switch and... Eureka! 12V (ish). This was looking promising. I plugged in the fuse and took her for a drive. Sadly, still no overdrive. When I got back, the fuse was still intact. I could also hear the relay clicking on and off. I'll test the voltage from the relay tomorrow - if I can get to it... But it's looking like the solenoid might be fried. Does that sound about right?

Thanks for all the suggestions. No time to do anything today, but I'll certainly follow up on theses. From NonMember's description it does sound more like an electrical problem.

We picked up our new (to us) GT6 Mk2 on Thursday. Purchased from a fellow club member. I haven't posted until now because we have been having too much fun driving it, but about 1/2 hr into the long drive home up the A1 the overdrive disappeared. She jumped out of OD in 4th. I reengaged and it was OK for a few minutes then the revs jumped again. I tried a few more times but with no success. I tried again after we stopped at Services for lunch. It worked for 5 minutes only, and that was the last time. I haven't been too concerned. OD was an optional extra after all, so we've continued to enjoy the car. But of course I would like get it working again as soon as possible. I had to crawl underneath today to rotate one of the exhaust U-bolts - to gain a critical inch of clearance. While I was there I took the opportunity to remove the gearbox filler plug and check the level. A few drops of (nice, clean) oil oozed out, so I guess the level is OK. Please help me to find my missing overdrive. I'm a complete newbie to classic Triumphs, so any suggestions or advice would be very welcome.

Thanks for the replies. I don't know about the dizzy, but to my untrained eye (and tiny photos), it looks like the Strombergs have been used. So I doubt the gearbox would have been changed - and I wouldn't know what to look for if it had. I do like to stir the box a bit, so this one might be more hassle than it's worth. I think I'll give it a miss and keep looking for "The One".

Apologies if this is the wrong section. I am interested in possibly buying a GT6 which has the engine from a 2500S. Before I got to check it out: What should I look out for? Is it a bad idea? Is there likely to be any problem with insurance? (I would almost certainly arrange it through the club). Sorry for all the questions. Thanks, Craig

Oooh. That's nice! I had seen the classified earlier. It looks a very different blue in that photo.

Thanks. We were considering dipping our toe in the world of classic ownership with a tidy Spitfire. But we are dog owners, and the GT6 has at least a small amount of space. I wanted a TR5 but they're outside our price range, and I'm not as keen on the TR6. What is the general opinion on Spitfire bodied GT6s? Or do they lose that tiny "rear seat" space?

Hello people. My name is Craig. I'm looking for a nice MkII GT6 as my first classic Triumph. I reckon I'll need all the help and advice I can get (which, of course will be gratefully received). Thanks, Craig
