Overheating woes, Parts are new
Stumped on an issue I'm having with cooling.
160 thermostat
185 fan switch
Brand new fan motor
New radiator
New waterpump
New hoses
radiator cap is new
Engine is a jasper reman from an 88 camaro
Sitting in the driveway and moving around temp stays steady right around 180 even on a hot day. But sitting in traffic it still overheats. I put a pressure gauge on the cold system and when i fired the car it went up to 30 psi.
I checked the timing and found that it was at 12*, Alldata calls for 6* on a 5 speed so i will be bringing it back to spec. Hose is also collapsing under throttle. I jacked the front end up to remove more air and the level did go down but still stumped. Some insight would be greatly appreciated.
Coolant is green, and the engine oil is clean

Re: Overheating woes, Parts are new
I don't think your problem is anything minor like timing or cap pressure. It's easy to see if the hose collapses. Drive it around to warm it and the park it and open the hood. Rev the engine with the throttle arm a few times and watch the hose. I don't think my gates hose has a spring and I don't think it collapses (though I haven't looked), my car does not overheat.
Another thing is to verify your fan is coming on at the right temp.
I recommend to everyone to buy the Holley universal radiator cap with the built in thermometer. It's an excellent double check on the dash gauge and lets you see what the engine temp is right there in the engine bay.

Re: Overheating woes, Parts are new
Do you have the correct rotation water pump (serpentine is CCW) and is your electric fan turning the correct direction to pull air through the radiator?

Re: Overheating woes, Parts are new
A lot of people don't know about the spring in the lower hose. This is one of the problems with these overheating or getting hot.

Re: Overheating woes, Parts are new
My new Gates does not collapse and has no spring. You should also be able to put a few tie wraps around the outside (LIGHTLY snugged and not overly tight) to prevent collapse.

Punkmaster98.....
You've already found your problem. Your water pump pulls suction from the bottom of your engine block. That's why the lower hose wants to collapse. When it does, that effectively cuts off ALL coolant flow in your engine. It would be he same as removing your serpentine belt and driving with no water pump...that'd be disasterous.
Go to any Autozone, Oreilleys, NAPA and get a Lower Hose with spring. I've never seen a lower hose that didn't have a spring inside.

Re: Overheating woes, Parts are new
No. Guys, your missing the point. Look at the second post....the pressure gauge pegged at negative pressure. That means the lower hose is collapsed and the pump can't help but to pull an extreme negative vacume. Punk....put the correct lower hose on and your problem will be solved.

Re: Overheating woes, Parts are new
I didn't know about the spring in the lower hose either. Let us know what your results are after the repair.
