It's normal for some fluid to be forced into the reservoir during operation due to fluid expansion and pressure. Usually the fluid in the reservoir will increase or decrease depending on what temperature the engine is at. Unless your truck is overheating I woudn't worry too much; just make sure the fluid level doesn't get too low or too high in the reservoir. If it is running hotter than normal and excessive amounts of fluid are being forced in to the reservoir you might have a blown head gasket. As far as the hoses collapsing; I have a 2001 Ford ranger 4.0 V6 and I noticed that the top radiator hose appeared to be collapsing in one of its bends. I installed a radiator clamp on the hose at that spot just to keep it round and from pinching itself off. It probably happens from the heat; just keep an eye on it. It may be that your hoses need replacing; I know mine did the same thing after just having been installed brand new though. God bless you and I hope everything works out for the best!!! : )

there is air in cooling system, you have to find out air bleeding screw on any of coolant hose. make lose that screw and start car let it get heat up and keep track on coolant level same time coolant tank cap should be open,coolant will flow out from that screw you keep top up coolant in tank, let this process go for 15 min and then tight the screw and close tank cap, problem is solved.

yes it is safe -your brakes will work normally only difference u will see is if u hit[stomp] on the brake hard will cause wheels to lock up[skid] check the sensors wiring ,connections and connection to clips the sensor is incorporated into the wheel hub but the wiring and clips connections are exposed which can get damaged or hit by road debris -if u remove the wheel will see wire running into back of rotor --to replace will have to replace the whole hub[wheel bearing] average price about $80 for part if diy

I have a 1986 Chevy Silverado with a 350 engine, why does my top radiator hose keep collapsing?

The hose collapses because there is air in the cooling system. If the system is properly full, the hose cannot collapse because water does not compress. If there is a leak in the system, you need to repair it, refill and bleed the cooling system, and ensure that the reservoir has a proper level of coolant in it. If there are no leaks in the system, then the reservoir (recovery) bottle could be low on coolant, allowing air into the system during the expansion and contraction that occurs as the coolant heats and cools. Another thing that can cause this issue is a defective/worn out radiator cap. I would recommend replacement of the cap, refill and bleed the cooling system, then top off the reservoir and then monitor for any further issues.

What cause lower hose to collapse after cool down

I would start by replacing the radiator cap. A bad cap can stop the flow of coolant from the coolant reservoir back into the engine when the engine cools down. This will cause a vacuum and collapse the hoses.

The other possibility is the lower hose is starting to get weak. This compounded with a radiator cap that is not functioning correctly will cause the the hose to collapse when the engine cools off.

2002 5.7l. What would cause the upper radiator hose to collapse?

When an engine is shut down, the coolant temperature begins to drop. If the vacuum valve in the radiator cap fails, the resulting vacuum in the cooling system can cause a radiator hose to collapse

My lower radiator hose collapses when I rev my engine the there is no thermostat in it. It is Isuzu rodeo3.2 engine

It is a BAD idea to run a car without a thermostat. A thermostat brings the car up to operating temp in a certain range. If the engine never gets warm, the rings never seat against the cylinder walls and the car will run very badly. If any radiator hose collapses while running the car, the vent on the radiator cap is plugged up. Replace the Radiator cap and the thermostat and if needed have the radiator cleaned out and use a proper mix of anti-freeze Isuzu recommends.

Blow out the radiator core from the engine side with compressed air to remove bugs and other debris. Make sure the cooling fan comes on when the engine gets to operating temp. If the car car has AC, turn it on which should start the fan immediately. If no fan action, try to turn the fan blade(s) which should turn easily with no noises. Check the fan fuse and fan relay. If the fan(s) come on fine, check the coolant level in the radiator core--it should be right at the top. Check the seal on the cap and replace it if it is decayed or damaged. Make sure the reservoir bottle is filled to the line and the connecting hose is in good shape. It is possible that the thermostat is sticking and not opening fully. Also, check the intake and outlet hoses to and from the radiator for firm condition without decay, collapse, or other damage. A hose can sometimes peel away a portion of the hose interior which can cause blocking. Hope some of this helps!

Sounds like the radiator is clogged, have the cooling system flushed, the water pump pumps water into the engine and it comes out the top hose to return to the radiator to circulate through it to cool, if the radiator is clogged the water pressure will build on the top hose, also look at the bottom radiator hose, if it collapses when you rev the engine the radiator is clogged, although sometimes the bottom hoses are reinforced with wire to prevent them from collapsing so just because they do not collapse it does not mean the radiator is not clogged.

Several things ... best guess, in order:
1. (very likely) Radiator fan is not blowing (turn on car and a/conditioner.
When compressor kicks in, the radiator fan must blow). If it ims not blowing,
the radiator fan motor may be burned out ($40).
2. Check / replace "cooling fan" fuse ($1) and / or "cooling fan" relay switch
3. Could be (not likely) thermostat sticking shut. Replace thermostat ($20)
4. Could be radiator hose collapse (not very likely) ($18)
5. Radiator clog or hose leak (possible)
6. Head gasket broken (not likely unless you don't fix current problem) ($150)
The more detail of the symptoms, the better we can assist you.
Hope this helps!
