Pressure Test of Coolant System - FJ62

[KG Cruiser]

I have noticed that the coolant in the tank is a little low when I check it every week or so.
I don't see any leaks (puddles on the driveway).

I rented a pressure tester from Advance Auto Parts.

The instructions say to pump it up to the systems pressure rating.

I can't find anything to indicate what the pressure rating is on the 62.

Does anyone know what I should pump it up to?

Thanks

I think the cap is rated 13 psi if I recall correctly. Id start there.

Awesome - thanks, I'll start at 13 psi

Pressure tested OK

I used the pressure tester I borrowed from Advanced Auto and pumped it up to around 13-14psi and the pressure held.

I don't see any puddles of fluid underneath either.

I did see a very slight area of wetness at a hose that connects to a hard pipe that tees. It is located near the firewall on the passenger side.

So I tightened this down another turn or so and I'll continue monitoring that area and the coolant level.

Might have a head gasket leak so you would be burning the fluid. There are kits to test that as well. Almost any good independent shop will test if for you for cheap.

did you pressure test the cap, too?
