Water/Coolant hoses are hard.

[NikolayVelkov]

Hey guys, I'm writing about a weird issue that I have. Let me explain.

4 years ago I got a 1991 Automatic Eddie Bauer with the V6 OHV. When I got the Explorer I noticed that when I drive it around the coolant hoses would harden and when I later park it and stop it for the day, they would soften up.

At some point the water pump broke and I took a lot of time to find a replacement for it. The car was out of action for almost 1 year before I found a replacement pump. After I assembled the whole thing together and drove it for a bit I started noticing that when I park and stop it for the day, the water/coolant hoses don't soften up like before, they remain a bit more stiff/hard, like there's pressure or air or something.

At times when I drive I feel like there's loss of power. I went over all the vacuum lines today to make sure they were all in good shape and that nothing is cracked and I thought about the hoses hence why I'm writing to ask you guys to see if anyone knows what the issue might be.

Before you ask, the radiator is new, the thermostat is new, the water pump is new, the hoses are new ( I tested the old hoses that it had a well, both the new ones and the old ones would harden up AFTER the new water pump )

Thank you!

Some thoughts:

(1). The heat from the engine and related expansion and pressure almost certainly causes the hoses to feel harder. When the engine cools, the pressure decreases, and the hoses might feel softer.

(2). If the new pump is performing better, you might have less heat and expansion.

(3). The new hoses are in better condition also, and this might not be as soft and pliable as the old hoses.

(4). Inconsistent power loss is probably an unrelated issue. Especially if you are not overheating.

(5). There are several posts in the Forum about getting air out of the engine cooling system. Use the “Search“ bar to find them.

(6). The OHV engine is tough, but be careful to avoid overheating.

Good luck and drive safe.

they are less pliable because there is more pressure behind them coolant flow should have no bearing on power loss, so as the ECT is reading accurately. agree with mr alligator on this one
