What kind of coolant temp should I be seeing….currently I am in very south Georgia and with this heat wave, outside temp is 100 degree F. The coolant temp is 190-203 F with a/c on and at 65 mph on flat ground.
I m praying for my old hoses. Think Im buying new ones when / if I get home….lol

I'm not going to ask what the coolant temperature is with the AC off, I don't want to be responsible for spontaneous human combustion.

That coolant temperature range seems fine.

Lol…I dont know…been to hot to turn it off and find out. Wife would never go for it…lol

really my concern is with the hoses that may or may not be 11 years old…😳

pretty sure that riding with it 100 degree is better than walking though…..lol

Hoses should be ok, I changed mine at 10 years old and really didn’t see any signs of decay, no cracks.
I’d be more concerned about the Dexcool, it should be changed every 5 years.

You have a good cooling system. If the hoses still have there shape and no bulging they are OK.

What could old hoses have to do with coolant temp, as long as they are not leaking? I don't get the logic; water doesn't care how old the conduit is, it just flows.

I think he's worried about old hoses bursting, higher temp means higher pressure and old rubber pops before the radiator cap releases into the overflow.

(Unfortunately, I am very familiar with this having driven poorly maintained fleet vehicles for years.)

I appreciate all the imput from you guys, especially since I dont have a long history with HHR’s. The situation is…I bought the car not running with 109000 miles on it….replaced the vvt selinoids….then chains, guides and water pump, oh and cam phasers. New Dex-cool, thermostat,burbed it…but I didnt change any hoses and they maybe fine. We use this thing as a work car transporting motorhomes all over the US…(use to do Canada before covid) so the cost of new hoses isnt nearly as bad as hiring a tow truck and paying to have it fixed on the road.
Does it have coolant hoses other than the radiator hoses and heater hoses? Honestly, I need to look it over….just havent yet.

Thanks

What brand hoses yall recommend…(GM of coarse)

Gates, AC Delco , use new gear clamps the upper hose between the rad cap and cylinder head is a cut to fit piece. I should have cut a piece out of the lower hose that was like new!
