Did the engine overheat? Is this why you put new radiator, pump and thermostat in? I hate to say it but you probably have a blown head gasket (cracked head/block). VERY, VERY common on this engine. Pull the oil dipstick and hope and pray it's not over full and foamy. Your new water pump could be junk out of the box as well. For your sake I'll keep my fingers crossed on a bad water pump.

Sorry so long to get back, found te problem. Some other shop had put a thermostat in a place where a therm doesn't go, what a huge pain! Took that one out and replaced the thermostat in the correct place and she's doing fine now, thanks again

A thermostat in the wrong place? That's a new one. Remind me never to take anything to that shop, LOL. Glad you got it straightened out.
