Is it normal for a radiator not to heat up?
An intact radiator should be naturally hot, but sometimes it may fail to heat up for various reasons.
Can a defective radiator cap cause engine to overheat?
A defective radiator cap will cause engine overheating in a number of ways. Three of the ways a radiator cap can cause overheating are, 1) Not holding in pressure and allowing the coolant to vent out or escape the cooling system. 2) No providing the proper pressure and not raising the boiling point.
Why is the hot water coming out of my radiator?
Additionally, rusting, internal corrosion or limescale build up in the system can block the valves. If the valves become blocked, then your radiator will not get hot. Besides the radiator not getting hot, other signs of blocked valves include hot pipes (not radiator), noisy radiators, and pinhole leaks.
What to do if your Radiator is low on coolant?
A low coolant level is one of the easiest cooling system problems to find. You only have to visually check your reservoir coolant level or radiator, to see if your cooling system is low on coolant. You then just need to top it off to the proper level.

What to do when your coolant temp goes up?
Turn the heater on at high speed. Rev the engine and hold for a few seconds. You don’t need mega high RPMs. Just enough to get good flow through the system. Check flow at the radiator. Temperature swings are common in colder climates. Thermostats are notorious for swings.
What should I do if my radiator is overheating?
Also, check between the condenser and the radiator as this tight spot can hold a lot of debris. A self-service car wash hose can clean out a lot of debris, just don’t get too close to the fins of the radiator and damage them or flatten them down. Your electric fan needs to turn on at certain times to keep your vehicle cool.
