radiator Hose outlets and inlets

Does it matter which way round the hose goes for the radiator off the engine?


20vt, in a mk1.. standard mk1 radiator (Inlet and outlets are on the offside)
Cheers

nah makes no odds you can flow coolant thru it either way

Beauty. Cheers dude.

So I'm running the engine for ten minutes.
The coolant gauge on the dash goes just past half way and there's no power to the radiator  fan connector?

The radiator it's getting hot but only on the side with the hoses.
The hose on the side of the engine, going into the top of the radiator Is hot, but the hose below, going into the thermostat is cold/cool still.
Does mean the thermostat is knackered? Or I've got a duff radiator?

what coolant temp sensor u got? bottom hose will be cold untill thermo kicks in and opens. is it a new thermo or one that was on engine as it was? for 10 quid get a new one in for piece of mind

Does the blower inside the car blow out hot air?

Could be a simple as an air lock in the coolant system?

Where'd you get a ten pound one from? I just paid £25 for one from vw

. And yeah, hot air was coming out the heaters/blower.

fan shouldnt kick in till around 3/4 on the gauge, what did you do about dash temp sender? use mk2 one, mk3 one or mk4+resistor

The dash temp sender (yellow/red wired) is just wired onto the sensor on the nearside of.the engine…

Just a quick one. The oil pressure  wires (one blue and the other yellow), which one goes on to the oil cooler? And where does the other go? Cheers

And the fan is kicking in now. Definitely the thermostat that was tits...

so the mk4 temp sensor? you need to fit a resistor inline with the temp sensor for that to work properly. I bin the mk4 sensor and add the 4 pin mk3 8v sensor instead, works with the mk4 ecu and mk1/2/3 dash properly. if your mk4 is late you need to splice the mk3 plug on, but note the pins are not the same layout:

for the oil pressure you bin the mk4 switch, take out the allen head blank from the spare hole then fit both mk1/2 pressure switches.

The coolant temperature switch I've got works fine with the mk1 dash. It might of been done before…
The part number on it is; PA66-GF30, ELTH, LUXEMBOURG.



And I'll get the oil pressure switches changed! Thanks dude

coolio, just thought best to make sure before you swap a load of other parts

Thanks dude
