Re: Engine burning coolant

Hello I use to work NW. Motor Welders a machine shop that did rebuilds on diesel cat motors and when placing the prechamber in, some times they forgot the shims to clock the glo plug and did they put a tat-a-tail in the rebuilt head also did they use a tapered plug for cracked bridge fix or a crack down the ports crack between the prechamber would not show up in oil

Re: Engine burning coolant

I agree.  Take it back to the Cat dealership, armed with all the facts you have and let them start it up cold in AM.  Was the overhaul done at a TEPS dealer or the actual Caterpillar dealership?   Not sure where you are located, but weather is starting to warm up and you want to make sure the problem can be duplicated.

Re: Engine burning coolant

I'd suggest bringing it back to CAT. Leave it there overnight so they can start it cold in the morning and see it smoke and burn coolant.

Engine burning coolant

Hi everyone. We had overhaul on 3406E CAT just a week ago at authorized CAT dealership. The engine smokes white smoke, and burns coolant at rate one gallon per 100 miles.

Here are the facts: there is no coolant in the engine oil; there is no coolant in the fuel, or fuel in the coolant; the coolant system has 8psi pressure; the engine starts rough, and smokes for 5-10min and then smoke clears, there are no coolant leaks. Any suggestions?
