I can give it a shot. All the hoses have been replaced. Maybe I’ll try to find a new control valve because mine is a little corroded

I’m assuming so? The lower hose exploded into the cab one time going the road so I think so? Lol how would I check if it’s flowing through? Also! I forgot to mention that my engine heats up more than usual when I try to kick the fan on. Maybe it’s backed up somewhere not allowing fluid to travel freely?

Hey guys, this is my second winter with my 77’ 620 Longbed and I think it’s time I spend some time trying to figure out why I don’t have any heat lol. All hoses are connected, I’ve taken the heater face plate off and cleaned out the few leaves that were in there. The air lever slides and opens the control valve (minor antifreeze leak from the control valve, not really sure why, debating on replacing) and I can’t come to a conclusion on why I don’t receive heat. The fan kicks on when I pull the lever outwards but I don’t get heat or any air for the defrost. Should I try to find a new core?

My heater core is blown. I haven’t been able to get heat since I bought it about 4 months ago

No I’m alwasys ontop of my fluids. My radiator was full. Brand new radiator and the thermostat is about a month or two old

It takes about 5 minutes to over heat. It normally runs about a 1/4 up the temp gauge

I recently installed a Weber on my 620 and it ran fantastic. Drove about an hour afterwards with no issues. I went to go start it up for work the next morning and as soon as I took off the heat spiked just below overheating. I shut it off hoping it’d cool down and it continues to do it. Also, after I shut it off it chugs a ridiculous amount before everything actualy calms down. If anyone has any idea on what’s wrong with it please let me know. I have to get this running before the work week starts

i Don’t know how to post pictures on this site. I’m using an iPhone if you know how

Hey guys, been thinking about selling my 620. Was curious if you guys would be able to give me a rough estimate of what it’s work. It is a 1977 with an l20b motor and a 5 speed manual transmission. Brand new aftermarket radiator, water pump, distributor and thermostat. Body is a little rough with a little rust. Completely primered though. A little hole in the cab floor but that’s about it. Thank you for the help

It wasn’t muffled before. It was straight piped and that snapped off about an inch or two below the flange

Hey everybody! I was gonna post some photos of my truck because I’m new to the community but I guess I’ll start it off with an event that just took place. My 77 620 is lowered and I’m used to having lowered vehicles so I’m used to being that guy who snails over speed bumps and dodges every pot hole. Well, this time I didn’t see it coming. I hit the hole, heard a crack and watched my exhaust role away. So I was curious if that is going to cause any trouble. I’ve been wanting my truck to back fire and let me tell you, she backfires and sounds like a motherfucker now but it’s loud as shit. If you guys have suggestions please let me know!
