Forum rules


When you put a new thread up in the Workshop please put your car's year and model in the thread title, along with just a brief indicator of the problem.

Car Year - Car Model: Brief description of issue. EXAMPLE- 1999 9-3. Problems starting when hot.

Please also add as much information as you can about the problem, to your post.

This will help us to help you, without having to ask basic details such as what car you have.


Threads with non-compliant titles will be moved to The Pit Lane (in which no replies can be posted, but the OP can edit the thread - upon which the thread will be released to the workshop forum)

Nb. Generic thread titles for truly generic issues that genuinely are not model or variant specific (such as "how do I change the spring in an forge wastegate actuator") are acceptable

**The first 5 posts for new users require individual moderator approval (which they will only get it if they are in line the rules of the forum). Please be patient and allow time for that to happen, and avoid duplicate postings.**

I'm trying to replace thermostat, and have opened petcock to drain rad. Nothing's coming out! The petcock is turning full quarter turn and I have a short hose on outlet, but not a drop.

If petcock is blocked, how can it be cleared? Any other ideas for getting coolant flowing?

Thanks.

I would do it back up and just disconnect the lower radiator hose. Bucket at the ready!

Thanks. That would be the sensible approach.

However since I saw access to the clamp on the lower hose was awkward, I decided to just take off the t-stat cover with a bowl underneath the car. About 2 litres came out that way, but at least the new t-stat is in now!

Funnily enough, I did exactly that on my 9000 years ago because I couldn't be bothered with a full drain and refill.

Glad you got it done!
