Replacing leaking thermostat!

lightpainter · 7th June 2020, 23:21

During the lock down because of the virus, I decided to do my own repair to replace my leaking thermostat, I watched a Youtube tutorial to see how its done the chap that had posted it removed the inlet manifold to do the job I thought that this must not be the only way as rover would not have designed the engine so you had to do all that extra work and proceeded to do the job from the side of the V by removing the carburetor intake!
Well I managed it but would not recommend it to anyone as it was a real pain in the ass to do; the problem was your working with one hand all the time and you cannot actually see what your doing because of the manifold being in the way so your doing everything by feel and you find that your lining up the ports on the engine block at the wrong angle, I damaged a couple of O rings because of this, but the car is up and running again!

carburetor intake - hopefully you mean throttle body

? I dont have a V6 so not sure what you are describing really, but it sounds like you are describing what I remember seeing once as the 'keyhole method'?

Yes the keyhole method is preferred, it is tricky but it’s far easier than removing the inlet manifolds.

Done it, bit fiddly, but as you said.

I am attempting the same job at the moment and I think Ive watched the same YT video. I took off the manifolds which was a pretty straight forward job and I can state that there is loads of access now. Im ordering the full thermostat kit from DMGRs at £75 and was wondering is it worth changing the plugs and coils at the same time.

I did my 190 through keyhole method and also did an how to photo by photo which PB stole another thread that needs sorting out.

keyhole method for me too. be careful not to be too heavy handed with the threads into the plastic manifold when re assembling. had to do my plastic thermostat many times before using this method. its cheaper as well as i always renew inlet manifold gaskets at the same time. so another plus for this method. however i have not had the pleasure since fitting my kaiser all metal stat ....

No Nick. "If it ain't broke, don't fix it".
