Silly question

OK, really silly question, but ref the direction of water flow in the 100/4.
Does the coolant go IN at the top of the radiator, and come OUT at the bottom ? This would mean that the water pump is therefore sucking the water up from the bottom of the radiator, pumping it through the engine, and then back into the top of the radiator..

Or is it the other way round ??

Just fitting up the electric pump, and I THOUGHT I was sure it goes in at the top an out at the bottom. Then someone suddenly queried it and said some cars go the other way round, and I hesitated......... And as we all know, he who hesitates is lost !!!

Help !!!

Giles

Giles,

See the atatched drawing from the service manual.
Through the thermostat into the top of the radiator and leaves the radiator at the bottom connection.

Just what are you going to find to do after the P2P? You continue to Wouk on the car and think about every detail.

Yes the coolant enters the engine at the water pump and leaves at the t’stat. It then enters at the top of the radiator and leaves at the bottom. I think that the “new thought” is to enter the radiator at the bottom and exit at the top. I think the reason for that is that it keeps the radiator full with no air pockets. This is the reason I chose to plumb the oil cooler on the race Sprite from bottom to top. I would say that you cannot reverse the flow on the 100 because of the internal design and if you choose to reverse the radiator it would require a lot of external plumbing.

Good luck and keep thinking up until the day you leave. When do you leave?

John

Thanks for confirming, Johan. As I suspected.
I was in Almere near Amsterdam last week ! My son lives there.

I ask myself the same question every day, John. “What will I do after P2P ?” Maybe do absolutely nothing for a couple of weeks ? But am thinking of getting a VW 1600 Fastback (Type 4 ?) and fiddling with it ! I had Beetles when young and always wanted one of those slick 1600’s ! Prices for them are not yet ridiculous like the Kombi and Beetle, and they would be ideal for these kinds of classic rallies because a) right age, b) they came with disc brakes and fuel injection so these can be improved and c) I know the engines well and easy to tune. And reliable. And also a bit different from everyone else ! (I like “different”
