Coolant Leak Only When Heater On

[ChristinaMVasquez]

Hello,

I’ve noticed a small coolant leak on the passenger side of my 22R carb’d engine. It drips a little all the time, but turns into a bigger leak when the heater is on.

It seems to be coming from somewhere under the intake manifold. Diagnosing is tricky because everything is hot, and most of the coolant evaporates before I can inspect it.

Has anyone experienced something similar or have ideas on where to check first?

i don't know .. according to my research the 22R engine is a Toyota engine.

are you in another part of the world .. not in the UK or Europe

if 22R is a typo .. more info required
