I've been sorting my dads van out, it had an oil leak on the rocker cover. I took all the radiator and that off, and put it all back together, and now the steering is hard, and it makes groaing noises. Right turns are impossible and left groans. Do you think it could be oil on the belt or something else? It is quite low on PAS fluid, but there is still some in the resovoir.
Ideas? Gotta go back out there now, garage is all open.
Cheers.
