Took the Griffith out on Sunday and the temperature was unbearable inside. The cabin fan is blowing hot air really making things uncomfortable. I read on this thread that a tap could be used in the event of the servo operated valve not curing the issue? There seems a few that say 'don't do it', mine is a 96 serp so I am looking for a definitive yes or no as i'd rather just blank it off and know it's going to be cool!

Cheers all.

The fan is blowing really warm air, i'm sure the valve is at fault. I just want to know for sure if I blank it will all be well?

The only way to tell will be to blank it and see. Or to get an infra red thermometer and measure the temperature of the pipes.

But, if that is your problem, why blank it? Why not replace it so the heater works as it should, hot and cold?

I can understand blanking it on a temporary basis to prove the fault, but not as permanent solution.
Even when set up correctly the word is it still doesn't work?

The Giff 500 owners I know say it does work.

Mine is a 400 so different.

I am sure that they worked when they came out the factory, and therefore there should be no reason that they cannot be made to work now. If they really didn't work, does that mean that all 500s drive round with it blanked off and no heater?
Having worked on this car for the last year, I am not sure the factory could actually assemble a ham sandwich biggrin

It's a dated design, many owners report the same issue.

After 6 hours driving through Spain a few years ago, the soles of my shoes fell apart as the glue had melted.... they do get warm.

I fitted a tap in the heater return about 10 years ago ( 1996 500 Serp) and have experienced no problems other than a much cooler cabin. You still get some heat soak but things are much more comfortable.

A good test last Sunday attending the Shelsley Walsh Hill climb. I covered 500+ miles in sweltering heat and the temperature guage was never above 85
degrees while on the move and usually much less. In traffic it did rise to 90 but with the fans cutting in meant it never exceeded 90.

The Griffith cooling system is much criticised but if its in good condition I believe it is perfectly adequate ( for a standard engine)
That's exactly what I needed, thanks. Will 3 bar and 110c cover it, given that it is going to be sat over the rocker cover?

The cooling system is working well in mine. I had the rad re-cored and an extra core fitted, it runs 80 degrees or less on the move and like your experiences is stable, never exceeding 90.

Good shout. I'll be looking at this tomorrow again. I have the valve tap now so we shall see what it does!
