I just bought a 1981 rabbit (l custom I believe) with the 1.6l diesel engine. It's not perfect, but it's definitely a good start! Before I begin to DD it there are several issues that I need to take care of.
To my knowledge the waterpump is good, but I'm going to be preemptive and replace the timing belt and tensioner, and I figure I might as well replace the thermostat and waterpump while I'm at it.
My problem is that I've read that 1981 is a changing point between the 30mm and 40mm waterpump, so it could potentially be either way. I was wanting to get the pump ordered this weekend, and the car is 35 minutes away at my work, so measuring the old pulley isn't my favorite option right now..
Is there a definitive change by the production date? And if I were to order the wrong one, would I still be able to use the other?
