No Coolant

igosaur · 07-17-2007, 10:26 AM

Just a quick question.

Assuming the the engine is cold, how far do you think I could drive with no coolant?

My overheating problem finally came to a head today when, a couple of miles from home, a hose buried deep in the engine bay somewhere decided it couldn't cope any more and promptly dumped the coolant all over the road!!!

10-20 minutes maybe, my fan was stuck on my fan shroud and didnt spin and i drove it on the freeway for about 20 minutes with no problems then right when i got home the needle jumped to red zone

Thanks for that

I did actually pluck up the courage and drive it home, luckily with no problems.

I know. I can't stay in denial any more.

I've done everything else so it must be the HG!! Better start saving.

I found the reason why the car had dumped all the coolant on the road.

When I put fresh water into the radiator to see where it was coming out, I found a small stub of a metal pipe at the back of the engine that had been covered with a rubber cap tied on tight with a jubilee clip.

I've now put this cap back on nice and tightly, refilled and since had no problems.

Presumably, if this cap was in the process of coming off it would not have allowed the cooling system to pressurise properly and hence cause overheating.

The real puzzle though is what is that pipe doing there in the first place. It seems to serve no purpose except to give the coolant somewhere else to escape from.
I'm still in denial about the BHG.....

With a stuck fan and driving at highway speeds you wouldn't have a problem till you slow down and lose the high airflow but with no coolant you won't last more than a few minutes. Ive tried to milk that situation before thinking I could just make it to work, then in less than 5 minutes the rattling started.....

Mine too. It's heated up on me during the test drive after my build.

But it was because I blew a coolant line, because of a 15 year old stock hose clamp.

A water cooled engine will overheat in less than 5 minutes with no coolant. No way in hell its lasting 15 minutes.

kudos, operating temp is already too far with no coolant. Dont do it or ur looking serious trouble.
