I knew I shouldn't have bragged on how much I like my Chevy.

Sometimes pulling the grill and radiator make things easier.

I used to have to work on Dodge Travco motor homes...no picnic either. Or A100 vans....
I thought about going that route, but I would have had to pull the A/C (which works), trans cooler, oil cooler, hoses, etc. And I'm a bit worried about breaking stuff, as it's 35 years old. There was enough room with the fan and shroud out. Got the new pump in, just have to bolt up all the brackets, hoses, etc. Been slow going, haven't had much free time lately. Just hope I don't wind up with too many leftover bolts, lol.
I always thought the Travco's were cool. Never seen one up close but pics I've seen they look neat. If I ever get one that needs work, I know who to call. :)
