Radiator Problem (diesel)

[ekiboy]

mga sir, may doubt kasi ako sa radiator ko, pag ini-istart ung L3 ko bumubulwak bulwak yung tubig hnd nawawala kahit nakarebulusyon yung makina, normal ba yun o may kailangan ako ipaayos? sana po matulungan niyo po ako. salamat po!

ser, your cylinder head might be cracked, corroded or bent, or your cylinder head gasket might also be corroded or has slipped out of place

maraming maraming salamat sir, kailangan ko po ba maagapan yung problema na yun? kung mpapabayaan ko ba yun ano po ba yung mga pwede pang masira? kasi po wala pa budget pang pagawa eh, galing kasi sa overheat yung sasakyan, kaya medyo nabutas bulsa ko eh.

sir follow up question lang, clear ko lang po, its either cylinder head or cylinder head gasket lang? tama ba pagkakaintindi ko? i mean walang problema yung cylinder head yung cylinder gasket lang or vice versa? tama po ba? pasensya na po.

prepare for the worst and hope for the best. have you been using antifreeze/coolant? have you had overheating and you added cool liquid in the radiator to quench it? this practice is a no no. you let the engine cool down gradually.

kasi galing sya ng overheat so pinaayos ko sya, after ko ipaayos parang nagooverheat pa din, nilagyan ko ng coolant, forgot the brand, i used it 1 month ago, after two weeks i need to overhaul the radiator, so the coolant drained by the radiator shop.

pag nag-overheat hindi ba dapat patayin ang makina?

further inspection of head and block will reveal which way to go. that is, you have to remove the head and check for warpage in the head and block. if head is warped, better buy surplus. grinding is not recommended on aluminums. if block, remove the block assy and have it disassembled and assembled by a competent machine shop.

is your van L3 gas or diesel? warping usually occurs at the side of the exhaust manifold where the hot gases pass through. check this out my friend: http://tsikot.com/forums/engine-fuel...na-hehe-78304/

Ideally hanggat umaandar ang sasakyan buksan mo engine compartment, yung rad cap dahan dahan tanggalin at maglagay ng fresh water without shutting off the engine para gradual ang pagbaba ng temperature.

Kapag bumubulwak usually nga either head gasket or cylinder head ang may problem or puwede din na both. In any case kelangan top overhaul niyan. Mura kung head gasket lang.

nice thread sir,salamat!. Yung L3 ko sir dating GAS, pinapalitan ko ng diesel D4BX yung makina, kasi gawa ng pagtaas ng gasolina, kaya naisipan ko palitan ng makina, mas malaki pa nagastos ko akala ko makakatipid ako hindi pala. pinatignan ko na sa dating gumawa sir, ang sabi sakin yung cylinder head nga daw baka may tama na, kakaoverhaul lang kasi baka daw hindi pa lumalapat yung cylinder head, hindi kaya back job yun mga sir?

there is a possibility the cylinder head bolts were not torqued to the right value or the cylinder head bolts were installed and torqued in the wrong sequence. as a practice in the past, the cylinder head and the cylinder block mating surfaces were sanded down in attempt to clean it. this removes the certain degree of roughness on the surface to prevent the cylinder head gasket from sliding too much during heat/cold cycles of the engine. if the clamping force of the bolts is not enough or the surface condition being too smooth and slippery, then the gasket keeps sliding and create a gap allowing pressurized gases and fluids to go past the gasket seal

to the TS, this might help a lot too...maybe the headbolts were not really torqued to the right specs and sequence. could be that your mechanic just did the "usual tightening". mine bubbled also about a year after the gasket job. retorqued it again to specs and right sequence, bubbling issue gone.
