1998 Toyota Forklift with 4Y engine running on propane. The oil on the dipstick is creamy in colour and texture. I changed the oil about six months ago and poured in 15W40 Rotella. The oil has about 80 hours running time on it. The level on the dipstick seems to have risen. I changed the coolant last year and used Detroit Diesel PowerCool Plus, which I believe is the same as Peak Final Charge, a non 2-eha OAT coolant. The coolant is red but I don't see any red colour in the oil.
There is a hose running from the rad to the overflow bottle and I took the end of the hose from the overflow bottle and inserted it into a bottle filled with water. No bubbles or coolant coming from the hose.
I could pressurise the cooling system and see if it holds pressure. Any other tests I could do before I yank the head off the engine?
